I ended up buying one for EAA. There have been too many nights previously where I have set up, cooled down, run cables, focussed, polar aligned, framed and then the clouds have rolled in for the evening. When I'm suspicious of a poor night, I plonk the Seestar down about an hour before it gets dark, go about my business, and turn it on after dark. If the clouds roll in, I've lost about 2 minutes.
I guess you have to use it within its capabilities and not expect the results that you might otherwise get from a decent setup. You can't avoid field rotation, it's a small uncooled camera and small objective. That being said though, it's a pretty capable unit for what its worth. Setup is a breeze, you can post process should you prefer to, and it's good to sit inside with those who would never venture out to the obsie and share the night's viewing. It's definitely easy to throw into the car if I'm going anywhere. My other rigs don't travel.
I guess it's horses for courses, but I'm really happy with it. It's just a matter of having the right expectation of what it can do. There are plenty of targets that it's capable of reaching with good results. I doubt that I'll be hanging a photo from the Seestar on my wall, but that's not why I bought it.
I've post processed a few objects in Siril (my post processing skills are poor) and the shots definitely come up better than without. Being colourblind doesn't help lol but I know others here face the same issue. The shots look ok to me, and then my wife will say, "Is that meant to be orange?" lol I've included a couple of lightly post processed shots just to show what it can bring out of B6 skies with about 2 minutes effort in Siril. Framing could be better but I'll get there. Sorry to everyone here who is a skilled astrophotographer - you may want to look away at this point lol.
The Rosette was shot a first quarter (that's my excuse). The Horsehead wasn't, so I'm still coming up with an excuse there - especially for the massive blowout on Alnitak and dodgy framing
Anyway, I guess it gives an idea of what you could reasonably expect from the unit if your post processing skills are below average and you don't have dark skies. Rosette was a 30 minute stack, Horsehead was only 12 minutes and had quite a bit more noise to deal with as a result. Rosette was stacked in Siril, and Horsehead was stacked in the Seastar and the final stack tidied up in Siril. Having noted that, the in-camera real time stacks were decent too, and certainly fine for a night of EAA.
