This is First Light with my new (used) QHY22 camera taken with the TS 107/700 triplet. I had some major frustrations at first with this camera, but I think I'm really going to like it now after working through some issues. Problem was with my hub, or the connection with the main USB cable going into the hub. I think it was just a coincidence the problems started when I started trying out the new camera. It would disconnect every time I slewed the mount. I always tied this cable up, with a strain relief, to the handles on my STF-8300. The QHY has no such handles, but once I found another option I haven't had the problem since.
There is still one thing that frustrates me, and if this has happened to anyone else I would love to hear about it and if you've figured out the problem or not. Sometimes when using frame and focus in SGP it takes 10-15 minutes to download the image. It timed out on me once. It doesn't happen every time, but it sure is aggravating when it does.
I'm trying to finish up one more "test" image tonight. Next step is to try the Riccardi reducer with the combo. Will give me roughly the same fov as I had with the 107mm using the 8300 camera, but will be at f/5 instead of f/6.5. Should be pretty nice if I can get it to work. I think it shouldn't be a problem with the smaller Sony sensor. It wasn't all that bad with my 8300, so I'm hoping things will look nice with the 694.
