EAA through 50mm finder scope

I wanted to try the camera through the finder scope with two goals:

see if it could be used as a enhanced finder scope (if I ever get a second camera),
to do some imaging with large objects (e.g. M31, M45, other large open clusters).

First I got the Orion deluxe 50mm f/3.2. Unfortunately I was unable to achieve focus with or without focal reducer. Then I got the Svbony 50mm f/4. With that one, I was able to achieve focus but only without the focal reducer. That means a fairly small field of view (2.2 deg x 1.2 deg) and much longer integration time to match the telescope.

I could not use the guide scope where I usually setup the finder scope because it runs into the focuser. So I set it up in the other dovetail shoe and used my regular finder scope also.

I started with the Moon and Jupiter through ASICap. I was not able to see any details on Jupiter then moved to DSOs starting with M31 which came out okay, but other galaxies were harder.

For star hopping, it is a decent setup despite the small FOV. It picks up more stars than the finder scope (magnitude 9 easily at 0.5s exposure and 10+ at 1s).
