These are interesting Devices. Stelina was their first product. The Vespera is a smaller package with basically the same software driving it.
Their intended use is casual imaging and stargazing. I can see the appeal it has for some. The ease of use.. pretty much one button. Very light, easy to transport.
When it comes to deepsky astrophotography.. the kind that I do.. this is limited:
In order to keep the price down the optics and sensors are basic.
Because it uses an alt/az style mount, the object your imaging will rotate in the field. It gets around this by cropping the final image, but that makes an already small fov even smaller.
I believe there are limitations on how long each exposure can be. You wont be spending 20+ hours exposure on a single target with this. They did introduce an advanced mode that would export raw files, which is better if you want to process them.
So with that said.. I'm not the target demographic. I can see this working for some people.. and if it helps increase interest in the night sky.. that would be good. :)
