I should have positioned M106 a bit higher in the frame; then UGC7282 would likely have fit into the shot as well.

I think it won't fit on this sensor (11x11 mm) with a 700mm focal length. In any case, I've noted it for the future. And I also corrected the frame name to make it accurate. Thanks!

It will fit perfectly, and with a rotation, UGC7290 will also fit in.

Greetings! good photos! Tell me, how do you find this telescope? I'm looking into it, but something is bothering me, I don't know what)

The 103 API tube is fine. It requires focusing every 1-2 hours at night, so a focuser motor is a must.

I wouldn't take it, because F/7 is very slow and one object requires many nights.

It's clear that it's F7, but there is a reducer that slightly improves the situation, and all similar tubes more or less have similar characteristics. I don't want a mirror for now; I started with a Newtonian, the hassle of collimation every time, and laziness, dear mother, is what it is.. Thanks for the answer.
