With many smart telescopes already on the market and more on the way, it’s becoming a challenge to decide which smart telescope best suits your individual needs. In this Best Buy guide, I compare various brands of Unistellar, Vaonis, ZWO Seestar, and Dwarflab’s Dwarf smart telescopes. Based on factors such as price, telescope type, camera, ease of use, real-world photo quality, storage capacity, weight, and size, this guide aims to help you make an informed decision. I conclude the comparison by discussing which smart telescopes are the best in their price class, ranging from $500, $1500, $2500, and a high-end $4000. I’ll be updating this Best Buy guide periodically as more smart telescopes become available.

The Rise of Smart Telescopes: Simplifying Stargazing and Astrophotography for All

Smart telescopes are becoming increasingly popular. The fundamental concept behind smart telescopes is to merely switch on the device, connect it to an APP on your smart device (phone/tablet), select a celestial object of interest, and then sit back and relax while the smart telescope handles all the challenging aspects for you. This includes locating the object of your interest in the night sky, tracking the object to keep it centered in your telescope’s field of view, and providing you with an excellent view of that object on your smart device (phone/tablet/iPad). Companies like Unistellar, Vaonis, and Dwarflab were among the first to develop smart telescopes with the primary goal of simplifying stargazing and astrophotography for ordinary people who don’t wish to invest days, months, or years mastering all the intricacies of our captivating hobby known as astrophotography. Due to its popularity, more established brands in the amateur astrophotography niche like ZWO, and more recently Celestron, have developed or are developing their smart telescopes.

Smart Telescopes Best Buy Guide: Choosing Your Celestial Companion

The primary objective of the Smart Telescope Best Buy Guide is to assist individuals in choosing the most suitable smart telescope. In this guide, I define a telescope as “smart” when the telescope is capable of autonomously locating, tracking, and capturing images of celestial objects in the night sky. This excludes traditional telescopes designed for naked-eye stargazing with an eyepiece. All featured telescopes are Wi-Fi-enabled and controllable through apps compatible with popular platforms like iOS and Android.

At present, this smart telescope guide includes the following brands: Celestron, Dwarflab, Unistellar, Vaonis, and ZWO Seestar telescopes. Some are older models but might still be relevant, as you could find used telescopes available from their original owners. The blog will be regularly updated to incorporate new smart telescopes as they become available.

I’ve taken various factors into account to help you find the ideal smart telescope:
  1. Price

Price

The ZWO Seestar S30, available for $349, is one of the cheapest smart telescopes on the market today, followed by Dwarflab’s Dwarf 3 and the ZWO Seestar S50, each retailing for approximately $499. These telescopes provide an economical entry point into deep-sky astrophotography. You can check out my detailed review of the Seestar S30 here, the Seestar S50 here, and my review of the Dwarf 3 is available here. If you’re interested in Dwarflab’s older model, the Dwarf 2, my comprehensive review can be found here.

Vaonis currently offers the Vespera II, starting at $1,590, and their newer Vaonis Vespera Pro, starting at $2,799. You can find my review of the Vespera II here. If you’re interested in the older, classic version of the Vespera, you can find my review here.

Unistellar has the Odyssey at $2,299, the Unistellar Equinox 2 at $2,499, the Odyssey Pro at $3,999, and the Unistellar EVscope 2, which tops the range at $4,899. Finally, the Celestron Origin Intelligent Home Observatory is priced t $3,999. Do these price variations correlate with differences in quality? Let’s explore further to find out.

Telescope types

Telephoto and wide-field design

Although marketed as telescopes, Dwarflab’s DWARF models feature telephoto and wide-field lenses instead of a traditional telescope design for capturing night sky images. This versatile combination makes DWARF telescopes ideal for both daytime nature and wildlife photography as well as nighttime astrophotography, serving as a multipurpose device.

Refractor telescopes

The ZWO Seestar (S30/S50) and Vaonis Vespera (classic/II/Pro), as well as the older Vaonis Stellina belong to the category of refractor telescopes, utilizing lenses to gather and focus light. The Vaonis Stellina stands out as a two-lens ED doublet refractor telescope, incorporating Extra-low Dispersion (ED) glass elements in its lens system. The use of ED glass effectively reduces chromatic aberration, resulting in sharper and more color-accurate images compared to standard refractors.

Notably, the ZWO Seestar S30 and S50 adopts a triplet Refractor Telescope design, featuring a three-lens system, with one extra-low dispersion (ED) element. The additional lenses in a triplet, compared to a doublet, contribute to further correction of chromatic aberration, enhancing image quality and color correction. ZWO does not specify the exact type of ED glass used in their telescopes (e.g. FPL-51, FPL-53, or FCD-100), but does ensure an apochromatic, sharp and color accurate view of the night sky with their Seestar telescopes.

The Vaonis Vespera (classic/II/Pro) adopts a Quadruplet Refractor Telescope design, incorporating a four-lens system with an S-FPL52 ED lens element. The additional lens elements in a quadruplet design, exceeding those in a triplet or doublet, significantly enhance color correction, resulting in exceptionally high-quality images in the field of astrophotography.

Reflector telescopes

Unistellar’s designs (e.g. Odyssey, Equinox 2, EVscope 2) all fall into the category of reflector telescopes, relying on mirrors to collect and focus light. Typically, a reflector telescope includes a curved primary mirror and a secondary mirror. Reflector telescopes are popular choices in astrophotography as they provide a large aperture at lower costs as compared to refractor telescope designs. But Unistellar’s telescopes are priced in the mid-range to high price categories in the smart telescope market.

This may be due to their innovative design where the optical tubes are prime-focus single-mirror telescopes, devoid of a secondary mirror or a coma corrector. In this design, the image directly reflects from the primary mirror to the camera sensor. This design may reflect some of the more expensive reflector designs on the traditional telescope market like Celestron’s RASA Telescopes.

Manual collimation is required for Unistellar’s Equinox and EVscope designs, but not for their Odyssey telescopes. Unistellar provides specific videos on how to achieve collimation. Despite these challenges, reflectors, with their larger apertures, excel in deep-sky astrophotography, capturing ample light for detailed celestial images.

Rowe-Ackermann Schmidt Astrograph

The Celestron Origin telescope features the advanced Rowe-Ackermann Schmidt Astrograph (RASA), an f/2.2 optical system with an ultra-wide field of view and sharp edge-to-edge clarity. Unlike traditional designs, RASA places the imaging sensor at the front, enabling faster and more efficient light capture. The compact 6” RASA in the Origin offers observatory-grade performance in a portable design. RASA’s speed and aperture surpass Newtonian reflectors, refractors, or other entry-level telescopes, delivering exceptional image detail in shorter exposures. While Celestron ensures the telescope is well-collimated out of the box, it is a mirror-based system, so periodic collimation may be required to align the camera with the mirror. Proper collimation is crucial to maintaining the telescope’s exceptional performance and capturing stunning astrophotography results.

Aperture, focal length, and f/ratio

In astrophotography, aperture and focal length are key. Aperture, the telescope’s lens or mirror diameter, determines its light-gathering ability—essential for capturing faint objects. Among smart telescopes, the largest apertures are in the Unistellar Equinox 2 and EVscope 2 (114mm), followed by the Unistellar Odyssey (Pro) with 85mm. The Vaonis Stellina, now only available used, remains the largest refractor at 80mm. The Vaonis Vespera and Seestar S50 have 50mm apertures, while the Dwarf 3 (35mm), Seestar S30 (30mm), and Dwarf 2 (28mm) offer the smallest apertures.

Focal length, the distance from the lens or mirror to the image plane, affects magnification and field of view. Longer focal lengths provide higher magnification, ideal for detailed shots. The Unistellar Equinox 2 and EVscope 2 lead with 450mm, followed by the Vaonis Stellina (400mm) and Unistellar Odyssey (320mm). The Seestar S50, Vaonis Vespera II/Pro have 250mm, while the classic Vespera has 200mm. The Dwarf 3 and Seestar S30 offer 150mm, with the Dwarf 2 telephoto lens shortest at 100mm.

The f/ratio, calculated as focal length divided by aperture, is crucial in astrophotography. Lower f/ratios enable quicker exposures for capturing faint deep-sky objects, while higher f/ratios are better for bright targets like the Moon and planets. Among smart telescopes, the Unistellar Odyssey (Pro) has the lowest f/ratio at 3.9, followed by the Unistellar EVscope 2, Equinox 2, and Vaonis Vespera at f/4. The Dwarf 2 has an f/ratio of 4.2, and the Dwarf 3 slightly higher at 4.3. The Seestar S50, S30, and the Vaonis Vespera II, Pro, and Stellina all share an f/ratio of 5.

Camera sensors: Resolution, Image Scale, and Field of View

Sony STARVIS (IMX) sensors

All the smart telescopes featured in this overview come equipped with Sony STARVIS IMX sensors. Sony’s STARVIS CMOS image sensors use back-illuminated pixel technology and exhibit remarkable sensitivity, rendering them perfectly suited for applications such as astrophotography, security, and other scenarios with low-light conditions.

Resolution (MP)

The Vaonis Vespera Pro leads with a 12.5-megapixel sensor (3536 x 3536), followed by the Vaonis Vespera II, Unistellar Odyssey (Pro), Dwarf 2, and Dwarf 3 at 8 megapixels (3840 x 2160). The Unistellar EVscope2 offers 7.7 megapixels (2088 x 1536), the Celestron Origin and the Vaonis Stellina both offer 6.4 megapixels (3096 x 2080), and the Unistellar Equinox 2 6.2 megapixels (2048 x 1536). The Vaonis Vespera (classic) and ZWO Seestar S50/S30 have the smallest resolution at 2 megapixels (1920 x 1080), with ZWO using a portrait-oriented sensor for smartphone alignment.

Image scale

Image scale measures how much sky each camera pixel covers, expressed in arcseconds, with 1 arcsecond equaling 1/3600th of a degree. For context, the Moon spans about 1800 arcseconds (0.5 degrees). In astrophotography, an ideal image scale is 1–2 arcseconds per pixel, balancing sharpness and avoiding overly bloated or blocky stars. The optimal scale also depends on the target’s apparent size and personal preference, whether for wide fields or detailed close-ups.

The Unistellar EVscope 2 and Equinox 2 offer the finest image scale at 0.66 arcseconds per pixel, followed by the Unistellar Odyssey at 0.93. The Vaonis Stellina achieves 1.24, the Celestron Origin 1.48, the Vespera Pro 1.60, and both the Vespera II and Seestar S50 2.39. The Dwarf 3 provides 2.75, while the classic Vespera and Dwarf 2 are at 2.99. The Seestar S30 has the highest image scale at 3.99 arcseconds per pixel.

Field of View

The Field of View (FoV) measures the portion of the sky visible in a single image. Wider FoVs are ideal for large nebulae or star clusters, while narrower ones are better for smaller objects like distant galaxies. For instance, the Andromeda Galaxy spans about 3°x1°, while the Whirlpool Galaxy covers just 11’x7′ (0.18°x0.12°).

Among smart telescopes, the Dwarf 2 has the widest FoV at 3.2°x1.8°, followed by the Dwarf 3 (2.93°x1.65°) and Vaonis Vespera II (2.5°x1.4°). The Vaonis Vespera Pro captures 1.6°x1.6°, the Seestar S30 covers 1.2°x2.13°, the classic Vespera 1.6°x0.9°, the Celestron Origin 1.27°x0.85°, and the Stellina 1°x0.7°. The Seestar S50 captures 0.7°x1.3° in portrait mode, while the Unistellar Odyssey provides 0.56°x0.75°. The EVscope 2 and Equinox 2 have the narrowest FoV at 0.34°x0.45°, just large enough to fit the full Moon.

Importantly, Seestar’s framing mode and Vaonis’s CovalENS can expand their telescopes’ FoV by two to four times by capturing and stitching multiple images into a single mosaic. However, this process takes more time, as different sections of the night sky must be photographed separately and then combined into the final image.

Smart Telescope Control via Wireless APPS

Each brand offers a dedicated app for wirelessly controlling their telescopes, available on both iOS and Android. After downloading and installing the app, you’ll be prompted to grant GPS access for precise sky tracking based on your location. Bluetooth and WiFi must also be enabled for a wireless connection. I’ve noticed periodic software updates, similar to other apps on your phone. Once the app is installed, simply open it, power on your smart telescope, ensure the mount is level, connect to the telescope’s WiFi, and you’re set to start. Keep in mind that some apps are more user-friendly and feature-rich than others, and updates often introduce new functionalities. Here’s my personal experience with different apps.

Seestar APP (S50/S30)

The Seestar app, designed for ZWO Seestar smart telescopes, is a well-crafted tool suitable for both novice and experienced astronomers. It provides key information like moon phase, weather forecast, and recommended celestial objects based on your location. The app features a virtual sky atlas, a searchable database of celestial bodies, and detailed information on selected targets. Users can easily select an object, and with a tap on “go gazing,” the Seestar S50 automatically slews to the target, centers it in the view, and starts calibration with 10-second photo stacking for improved views. Special modes for lunar, solar (with filter), and planetary observations are included, with automatic camera settings and up to 4x digital zoom for planetary views. The app also allows users to capture up to 2x the original field of view and rotate deep-sky objects to their liking. It also offers a community tab for interaction and a scenery mode for daytime use, making it versatile for activities like birding or wildlife photography. Its automation enhances the stargazing experience with both video and photography capabilities.

Singularity APP (Vaonis Vespera/Stellina)

Vaonis offers the Singularity app for their smart telescopes. The main screen provides a weather forecast, upcoming astronomical events, and articles on using Vaonis telescopes and image processing, with direct links for purchasing accessories. In the exploration tab, users find recommended targets, as well as categorized listings of celestial objects, constellations, and Messier objects. The constellation feature details observation times, directions, altitudes, and more about selected targets. After a brief initialization, Vaonis telescopes automatically slew to the target, perform autofocus, and deliver live feeds on connected devices. Solar mode, requiring a solar filter, includes a feature showing the Sun’s size from different planets. The app also supports collaborative observation, letting multiple users join and control the telescope remotely. The “plan my night” option allows users to schedule sessions, and the covaLENS panorama mode capture larger parts of the night sky for large objects. The app is beginner-friendly and intuitive.

Dwarflab APP (Dwarf 2 and 3)

The Dwarflab app is designed for both nature and wildlife photography, as well as astrophotography. It offers live views from wide-angle and telephoto lenses, with a smooth switch between them for capturing subjects. The joystick-like button controls telescope movement, and the speed dial adjusts slewing speed. Although automatic tracking is somewhat inconsistent, it can follow moving subjects. The app supports photo, video, and timelapse modes for daytime use. With the Dwarf 3, Dwarflab introduced a virtual sky atlas for easier object search, tracking and an experimental EQ mode (polar alignment procedure), allowing users to capture longer exposure photos and collect more faint light from deep-sky objects. EQ mode also reduces problems concerning field rotation, which is common in smart telescopes and alt-az tracking. The app also includes automatic settings for Sun and Moon capture, adjusting shutter speed and gain for detailed observation. While setup is more involved compared to other apps, it offers manual control over camera settings, and astrophotography mode offers features like live stacking and AI noise reduction.

Unistellar APP (EVscope 2, EQuinox 2, Odyssey)

The Unistellar app provides an intuitive home screen with recommended targets and helpful guidance for first-time users. It features categorized lists of celestial objects—such as solar system targets, nebulae, galaxies, star clusters, and stars—along with a searchable catalog of over 5,000 objects. Selecting an object reveals its description, location, and optimal viewing times. The app supports up to 10 connected devices, highlighting the brightest and best-positioned objects for easy observation. Once a target is selected, the telescope automatically slews to it and begins live stacking images. Additionally, the app connects users to a global citizen astronomy community, enabling participation in science missions and sharing stunning astrophotography results. It makes exploring the universe accessible and engaging for all levels of stargazers.

Celestron Origin APP (Celestron Origin Intelligent Home Observatory)

The Celestron Origin’s companion app transforms how you explore the night sky, making astronomy simple and engaging. Setup is effortless with StarSense technology: place the telescope outside, turn it on, and connect to the app. Within minutes, Origin aligns itself by mapping star patterns and is ready for use. The app offers an intuitive planetarium interface powered by SkySafari™, letting you explore the sky in “compass mode.” Tap any highlighted object or use the “Tonight’s Best” list for curated celestial targets based on your location and time. Once selected, Origin automatically centers the target, tracks it, and starts capturing 10-second exposures at the press of a button. Real-time AI algorithms process images to enhance detail while preserving your data. Share the experience with friends through live device streaming or cast to your TV. Origin ensures everyone, from beginners to experts, can enjoy breathtaking cosmic views with ease.

Photo & Video formats

All smart telescopes in this overview support multiple photo formats like JPEG, FITS, and TIFF files. JPEG (Joint Photographic Experts Group) utilizes lossy compression, discarding some data to achieve smaller file sizes. Because of their limited size, JPEG files can be readily shared with friends and family, or on social media.

In contrast, FITS (Flexible Image Transport System) files employ lossless compression, crucial for preserving scientific data in astronomy, and are stored in a 16-bit format, which provides more color depth. These higher-quality FITS files are often used for post-processing, where you can (re-)stack multiple images of a celestial object and recreate your final image to your liking. While smart telescopes do the stacking and processing of pictures automatically for you, there’s also the option to download the FITS files on your computer and use third party Astro-processing software to enhance your pictures. Post-processing Astro-pictures has its learning curves, but it gives you more autonomy to create astrophotography pictures to your liking.

TIFF (Tagged Image File Format) files are used by smart telescopes to save a final, stacked picture of a celestial object in 16-bit lossless compression, preserving the image quality and true color of the picture. They are also better suited for post-processing images, as compared to JPEG files This creates two options; you can either recreate the entire stacking process by restacking the individual fits files, or you can take the automatically stacked TIFF file for further processing.

In addition to this, the Dwarf 2/3, and Seestar S50/S30 also support video. The Dwarf 2 and 3 include an option to take MP4 videos, while the Seestar S50 stores videos in MP4 and AVI RAW format. MP4 files have a smaller file size due to the advanced compression algorithms and are great for immediate sharing. The Seestar S50 also stores solar and lunar videos in uncompressed 16-bit AVI RAW, which is excellent for manual post-processing using third party software tools like Autostakkert! and Registax.Videos are also exciting as it provides you with the opportunity to record lunar and solar eclipses. Note that you can also stack and process FITS images using autostakkert.

Image Quality

Real-world images best showcase performance. Here are some pictures I took with some of the Smart Telescopes in my light-polluted Bortle 7 urban sky. All images were stacked and processed by me, with exposure times ranging from 45 to 90 minutes.

Storage capacity and Battery life

All smart telescopes have internal storage capacity to save your photos, which can be transferred to your computer, smartphone, or tablet after an imaging session. More storage capacity is useful as it relates to less time needed to transfer files to other devices and delete images to free up space for the next imaging session. In that respect, the Vaonis Vespera Pro stands out with a storage capacity of 225GB, followed by the Dwarf 3 Smart Telescope at 128GB; the Seestar S50/S30, Unistellar Equinox 2, Odyssey and EVscope 2, as well as the Dwarf 2 Smart telescopes, all have a 64GB storage capacity. The Celestron Origin has about 45GB storage capacity, the Vaonis Vespera II only has 25 GB of storage, and the Vaonis Stellina and classic version of the Vespera only have 10GB.

All smart telescopes have internal batteries that can be recharged after an imaging session. Longer battery life is useful so you don’t have to worry about forcefully stopping an imaging session because your smart telescope runs out of battery. In that respect, the Vespera Pro and Unistellar Equinox 2 boast 11 hours of battery life, followed by the Unistellar EVscope 2 rated at 10 hours. The classic Vaonis Vespera lasts for 8 hours, the Seestar S50/S30, Dwarf 3, and the Celestron Origin all boast about 6 hours, the Unistellar Odyssey and Vaonis Stellina have about 5 hours of battery life. Finally, the Vaonis Vespera II and the Dwarf 2 only run for 4 hours before needing a recharge. The Dwarf 2 is the only telescope with a removable battery. Most smart telescopes can be recharged using a USB-C cable, also while in use, except the Classic (first) edition of the Vaonis Vespera and Stellina, which needs a proprietary cable that comes with the telescope for recharging.

Weight and Size

The portability and size of these smart telescopes may also be important, especially if you’re planning to take them on to remote places for stargazing. The Celestron Origin is the heaviest smart telescope weighing 18,9 kg, followed by the Vaonis Stellina at 11kg, the Unistellar EVscope 2 at 9kg, and the Unistellar Equinox 2 at 7kg. Significantly more portable are the Vaonis Vespera models at 5kg. The Unistellar Odyssey weights 3 kg. The Seestar S50 is only 3kg, and by far the most portable devices are the Seestar S30 at 1.65 kg, and Dwarlab’s Dwarf 3 and Dwarf 2 smart Telescopes, weighing only 1.3 and 1.2 kg, respectively.

As for size, the Celestron Origin (61 x 66 x 121 cm) is the biggest telescope. The Unistellar Evscope 2 (77 x 33 x 26 cm) and Equinox 2 (65 x 23 x 12 cm) are also pretty bulky, although they do fit in a backpack, followed by the Vaonis Stellina (49 x 39 x 13 cm). All models of the Vaonis Vespera are significantly smaller (48 x 20 x 9 cm), as well as the Unistellar Odyssey (43 x 20 x 13 cm), and easily fit in a backpack. Finally, the Seestar S50 (14 x 13 x 26 cm), S30 (21 x 14 x 8 cm), Dwarf 3 (20 x 6 x 13 cm) and the Dwarf 2 Smart Telescope (20 x 5 x 13 cm) are the most portable smart telescopes in this overview.

Astrophotography filters

Good quality astrophotography filters play a crucial role in mitigating the impact of light pollution in urban settings while enhancing the nebulous details in your astronomical images. Additionally, employing a solar filter is imperative for safeguarding your smart telescope by reducing solar energy, and enabling the observation of sunspots. Remember, never gaze directly at the sun, as it poses a risk of blindness.

The Seestar S50 is equipped with an internal light pollution filter to counter urban light pollution and enhance signal to noise ratio. The Seestar S30 is equipped with a Dark Field Filter (reduces noise), a UV/IR Cut Filter (blocks infrared light interference) and a Light Pollution Filter (Optimized for OIII and Ha wavelengths, great for nebulae). Both Seestar telescopes also include a solar filter without any extra charge. The Dwarf 3 has a magnetic solar glasses with ND filters that come with the telescope to place in front of the two lenses. The Dwarf 3 also comes with additional VIS filter for daytime use, an internal Astro filter to combat light pollution, and a Duo band filter (Ha, Oiii) for deep sky astrophotography.

For an enhanced experience, the (older) Dwarf 2 model has a deluxe version at an additional cost of around $120, featuring a 1.25″ solar filter and a 1.25″ ultra-high contrast filter. It is advisable to skip the UHC filter from Dwarflab and opt for the superior 1.25″ dual-band filter (e.g. from ZWO or Optolong), which can be easily mounted on the Dwarf 2.

The Vaonis Vespera provides customization options with separately purchasable dual-band, light pollution, and solar filters, ranging from $199 for a solar filter to $399 for a dual-band filter. Not cheap, but the filters do their job well. The older Vaonis Stellina came with an internal light pollution filter and a solar filter, available for $199.

the Celestron Origin has a built-in filter drawer that accepts standard 1.25” and 2” format filters. This allows you to install optional filters, which can be especially useful in imaging nebulae in light-polluted environments like the typical suburban backyard. Celestron offers an optional ‘Nebula’ filter (Hydrogen-alpha, Hydrogen-beta, doubly ionized oxygen) for $199.  

Unistellar only offers a smart solar filter for the Evscope 2 and Equinox 2 ($249) and Odyssey ($199). Unistellar asserts that its software is crafted to combat light pollution. While they may employ techniques like dynamic background extraction, background neutralization, and color balancing in their capturing software, like I do when I’m processing my astro-pictures, the specifics remain undisclosed…

  1. Hello greetings, I wanted to ask if the Seestar will have a pro version? with more aperture and longer focal length, greetings from Chile

    1. Let’s wait and see. ZWO usually announces new product updates at AP conferences like NEAF, next one is in April 2024.

  2. I was wondering if any of these can work while plugged into a battery pack. That would extend the battery life but I don’t know if that would interfere with any of the functionality.

    1. Hi Scott, I tested the Seestar S50 and the Vespera classic/II, and they both work fine when an extra battery pack is plugged in.
      They re-charge while imaging, no problem.

  3. Background: I own the Meade LX90 12″ ACF, Televue 102 Refractor, Orion 150mm Maksutov and Lunt LS152THa solar conventional telescopes. In 2020 I purchased a Vaonis Stellina to use in public outreach during Covid. Last year I ordered the Seestar S50 and then a month later the Vaonis Vespera Pro upon its release. I sold the Seestar when it arrived, unopened. I’m awaiting delivery of my Vespera Pro.

    Nice review with an excellent comparison of features. However, you left out one critical parameter: sensitivity. I was happy with Stellina when I received it in June of 2020, however, it compares poorly with today’s offerings. Stellina is good to Mag 13, eVScopes can image to Mag 18 and Vespera Pro is claimed to be Mag 16. I have a friend that has imaged the Hershel 400 with his eVScope II. That would not be remotely possible with Stellina because of the wider field and 5 mag lower sensitivity. I have a friend with an original Vespera and his images of M51, Whirlpool Galaxy, are superior to Stellina’s despite its 1/3 pixel resolution and 50mm vs 80mm aperture optics. Vespera supposedly also has a sensitivity of mag 13 but it seems to do better than that. I suspect that its Sony IMX462 camera sensor has better sensitivity than Stellina’s Sony IMX178 chip which is now a 11+ year old design. And the precision apochromatic quadraplex lens optics may also help Vespera. It appears that Vaonis has stopped selling Stellina although I have not yet seen a formal announcement, it’s always “out of stock”… it’s just technically obsolete. I’m looking forward to seeing how the new Vespera Pro performs.

    [ I’m surprised that Celestron’s new Origin Telescope uses an IMX178LQJ, Although it is a more advanced unit with better features, it still has the same 6.3 mega pixel resolution of the earlier IMX178 family sensors used in Stellina. Without Stellina’s mechanical field decorator, Origin will necessarily produce more misaligned pixels in the software rotation matrix transform, necessarily yielding a softer image.]

    So, adding sensitivity to your review would be extremely useful.

  4. It would be useful to know which scopes here can connect to an existing wifi network. If the scope can only use it’s own wifi network then range can be a problem if you want to go indoors, as well as it means your phone will no longer have internet access while connected to the scope (unless you can use the phones cellular connection). The Unistellar eVscope eQuinox 2 seems to have a particularly limited wifi range.

    1. Seestar, Dwarflab an Celestron APPs have a station/STA/network mode that connects your smart telescope to your home WiFi network. Vaonis and Unistellar only have a direct WiFi connection and do not (yet) support a network mode. Beware that APPs are updated frequently (especially Seestar and Dwarflab seem to be very active) so this and other functionalities may change in the future.
