Absolutely non-functional. Switching to any mode after the initial install just causes the camera to shut off. No amount of messing with settings makes any difference. Edit: You took hundreds of dollars from us for a product you knew didn't operate as advertised. We returned the faulty telescope and moved on with our lives. There is no reason to trust your company again after your first attempt to defraud us.

Hi Jackson, first of all sorry for the delayed reply. The camera-shutoff loop is one of the bugs addressed in v1.9.1 on Galaxy S22 Ultra. Please update Gravity from the Play Store and try again — no settings to tweak this time, it should just work. — Brian from Vaonis

I've had better luck than a lot of the 1 star reviews. Hestia itself I had to go to the camera store to get an adapter ring so it would mount on my tripod. I was able to get some good pictures of the eclipse in San Jose, CA, where we only had about 35%. The time lapse video option did not do well, very bouncy. I just got my first night photos and this is where I see a lot of room for improvement. I'll probably attach a finder scope to make up for features that ought to be in the app.

Kept freezing taking pictures waiting for stabilization. If it s going to be that sensitive you needed a sturdier tripod. A light breeze will cause it to shake. I could see sun spots if I blocked some of the light by cupping my hand around the lense. It would be nice if there were a way to adjust brightness in the app. If there is a way I didn't see it. Hopefully it improves.
