Group of galaxies: M105, NGC 3384, NGC 3389, M96
The third object, i was really impatient, was a group of galaxies with M105. I did 30 exposures with 60s each at ISO 800. Here the stacked image. (Stacked in December 2021 with Affinity using DARKS and BIASES and also some FLATS from 2 weeks later). I simply had no result with enough pixels.
Lessons Learned
This evening i used my unmodded CANON EOS M100. The mount control was still used with APT. To control the M100 i used the iOS App “CC & C” which works perfect.
What i really hated for several month was the fact that i did not really found the objects in the sky with my goto mount. I always had to use the arrow keys of the mount control to find the object. It took me several month to fix that later.
Focusing with a Bahtinov-Mask worked really well.
