In 2022, I did only a few simple purely visual "deep-sky observations," which might be of interest to other beginners and are therefore described here. They took place in Mühlhausen/Kraichgau.
In 2022, I observed mostly the following sky area (some observed objects are indicated): :

The observations were done in the first half of the year 2022.
The observations took place in Mühlhausen/Kraichgau (Germany):
In Mühlhausen/Kraichgau, the sky was not particularly dark (up to SQM 20).
|Observed Objects||Details, Remarks||Further Observations and Remarks||Devices Used||Eyepieces Used|
GN: M 42
|M 42 with C5, not very good (and before that the Golden Handle)
|C5 on AZ Pronto mount||unknown|
| OC: M 11
GC: M 3, M 5, M 10, M 12
C: C/2017 K2 (PANNSTARS)
|Order: M 10, M 5, M 3, M 11, M 12 (indirec seeing); M10 and M12 also found together- but not the comet C/2017 K2 (PANNSTARS) in the same field of view...
PS 72/432 with 40 mm, 26 mm, and 16mm on AZ-GTi ; iPhone with SynScan app;
1-Star alignment using Arcturus; at first, I simply let track Arcturus. Observations from about 11 p.m. on (SQM 19-20).
The globular star clusters were all faint; M 12 was mostly only visible via movements or indirect vision; M 11 could not be resolved into stars.

1-star alignment using Arcturus; at first, I simply let track Arcturus. Observations from about 11 p.m. on (SQM 19-20).
First round : M 10 seen, M 12 only guessed, M 107 not found, M 5 better (SQM 19.5); M 3 similat to M 5 (not as good accessed (it was still in the FOV), but I was able to center it) (SQM 19.7), comet not found...
|C5 on AZ-GTi mount (Celestron PT)||32, 24, 16 mm, f/6.3 reducer/corrector|
Bold: First observation during this observation period; all observations done in Mühlhausen/Kraichgau (MH); G = galaxy, OC = open star cluster, GC = globular star cluster, GN = galactic nebula, PN = planetary nebula, P = star pattern, DS = double star , C = Comet
