Is Vaonis Vespera 2 still worth it

The Vaonis Vespera II was released in early 2024, which means it’s no longer the latest smart telescope on the market. In the fast-moving world of compact astrophotography gear, that’s enough time for competitors to catch up or even surpass it in some areas. Despite being over a year old, it’s still one of the most expensive smart telescopes available today, and that price is hard to ignore when cheaper options like the Seestar S50, Seestar S30, and Dwarf 3 are offering solid performance at a fraction of the cost. With a price tag that puts it well above most of the competition, the question isn’t just whether it works well, but whether it does enough to justify that cost in terms of features, image quality, and overall experience. It uses a 50 mm aperture with a 250 mm focal length, which is right in line with much cheaper models, and the optical hardware by itself doesn’t really explain the premium. What sets it apart is the Sony IMX585 sensor, which does produce clean, sharp images and supports high-resolution output through Vaonis’s CovalENS mosaic feature. This pushes the final image resolution up to 24 megapixels, which is more than what most smart telescopes can offer, but the native 3840 x 2160 output isn’t radically different from what the Seestar S50 already delivers. The field of view is also slightly wider with mosaic mode, making it easier to capture large deep-sky objects in a single frame. It includes a built-in field flattener too, something that helps with edge sharpness and reduces distortion.

Is the Vaonis Vespera 2 worth its premium price in a crowded smart telescope market?

Still, these imaging improvements don’t change the fact that it can’t shoot long exposures. Unlike the Dwarf 3 or Seestar S50, the Vespera II doesn’t support equatorial tracking, so it can’t take longer subs without trailing, which limits deep sky performance. You get nice images quickly, but you can’t push it very far beyond what it captures in short bursts. That’s a big limitation for anyone trying to squeeze out more detail or improve dynamic range through extended integration. In terms of automation, the software is user-friendly and handles most of the imaging process for you, including sharpening, contrast tuning, and stacking. For a beginner who doesn’t want to edit raw files or spend time learning post-processing, this helps, but it’s something the Seestar S50 also handles well at a much lower price.

So when you stack it up against the current competition, the Vespera II offers good image quality and a premium experience, but it’s hard to ignore how close other smart telescopes are getting in terms of results for much less money. It doesn’t deliver a major leap in optical performance or software features to truly justify being two or three times more expensive than some of its rivals. The build quality is solid and the interface is polished, but for many users, the value just isn’t there unless you specifically want the Vaonis ecosystem and are willing to pay extra for that refinement. Otherwise, more affordable models can deliver 80 to 90 percent of the experience for a lot less.

ScottC Astrophotography: Half moon

A test run of the telescope began with a basic target: the Moon. The autofocus took some time, but it was able to find the Moon on its own, which some smart telescopes struggle with. Once locked in, the live view displayed lunar detail clearly, though it wasn’t possible to record high-frame-rate video for stacking. Without that function, it’s harder to get the sharpest possible lunar image, even though the live view did show crater detail.

Target selection for deep-sky objects is handled through a menu of tiles, each labeled with recommended exposure times. Selecting M104, the Sombrero Galaxy, the system was able to track and capture the target easily. After about two hours of integration, the image showed significant noise reduction and improved clarity. The camera cleaned up the signal well with extended exposure.

Mosaic mode

Another test focused on the Milky Way core using the mosaic function. This mode stitches together multiple panels to form a wider view. Compared to similar functions on other smart telescopes, the CovalENS feature worked quickly and produced consistent star shapes across the entire mosaic. The detail and overall structure of the final image were solid, with noticeable sharpening and correction during the mosaic process.

The wide field of view from the IMX585 sensor is a key strength of this telescope. It allows users to frame larger targets like the Andromeda Galaxy or the Orion Nebula. These weren’t available to test due to the season, but the sensor and optics combination should handle those objects without issue. Even with smaller galaxies, there was enough resolution to zoom in without the image falling apart.

Another tool built into the system is the AI assistant, which provides context and background information about each object. It explains what you’re looking at, how far away it is, and some history. For users trying to learn the sky, this adds an extra level of information and can make it easier to remember and recognize objects later.

There are tradeoffs to be aware of. The price is high compared to alternatives. At $1,690, it costs more than other smart telescopes that offer many of the same features, sometimes with extras like included filters or equatorial tracking. If the goal is to use this telescope as a way to learn astrophotography, the budget might be better spent elsewhere. A simple mount like the Sky-Watcher Star Adventurer GTi, a basic 70 mm refractor, and a dedicated camera like the ZWO ASI585 or 533MC Pro could provide a more powerful and flexible system for about the same cost. That setup would require a learning curve but would give better control and teach more about imaging.

Filters are not included unless purchased as part of a bundle. Even then, the filters are priced high. This adds to the total cost and makes the Vespera II feel like a platform where each upgrade adds significantly to the base price. That includes filters, accessories, and any future software features.

The other major limitation is the lack of equatorial mode. This prevents the telescope from being used for longer integrations, which is a core part of improving image quality in deep-sky astrophotography. Without that, users are limited to stacking short exposures, which won’t always bring out faint detail, especially on targets like nebulae or distant galaxies.

Overall, the Vespera II functions well as a smart telescope for electronically assisted astronomy. It excels at automation, has a fast and efficient mosaic mode, and delivers usable images right away with minimal user input. For those who want to observe and share without going deep into gear or editing, it fits that role well. But for users who want to learn the full process of astrophotography, from camera control to exposure planning to post-processing, a traditional rig may be a better long-term investment.

The Vespera II isn’t trying to be a high-end imaging platform. It’s built to give users quick access to the night sky with minimal friction. That makes it good for casual sessions or quick imaging runs when you don’t want to set up a full rig. It also has potential as a teaching tool for younger users or for outreach events, where simplicity is important.

Still, the price and lack of flexibility make it less appealing to those who want room to grow. Once a user learns the basics and wants more control, they may outgrow the Vespera II quickly. If budget isn’t an issue and convenience is the top priority, it’s a strong option. But for anyone who wants to build a long-term astrophotography workflow, it may make more sense to start with separate components and learn how they work together.

In the end, the telescope does what it sets out to do. It makes capturing space easier. But what you gain in automation, you give up in control. That’s the tradeoff. Deciding whether it’s the right choice comes down to what you want out of the hobby, simple observing or hands-on imaging.
