Dear colleagues astrophotographers.
Until now, I was using simple rig - tripod with iOptron Skyguider pro, Canon camera and Canon Lens.
Few days ago I bought astrocamera ZWO ASI 533MC pro and connect it to Raspberry Pi 4 with Stellarmate. Yesterday, I tried to capture M31. I realized, I don't know how to focus.
So, my rig is, tripod with iOptron Skyguider pro, ZWO ASI533 and Canon Lens (I like to use various focal lengths). I am using stellarmate app in Android phone and don't have any additional hw such a guidescole/camera, focuser...
What I need is possibility of liveview and manual focus with this setup (something similar as via DSLR camera liveview focusing) . I didn't find answer in various forums and tutorials. Is there someone, who can give help me please?
Also, is there any way how to setup aperture? Or should i set the aperture via DSLR and then, with tesired value remount lebs to ZWO ASI?
Thanks in advance.
