Deep Sky Observations 2022

Conditions | Observation Overview | List of Observed Sky Objects | References

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.

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.

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).

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...
Second round: M 57 not found, M 10 was OK (SQM 20), M 12, again with 32mm, was somewhat besser to recognite, but the sky background was bright
Final targets : M 13 qith 32 and 16 mmthe best of all GC; M 92 with 16 mm nit in the FOV (or at the edge...), but found it with 32 mm and "caught" it, smaller, but brighter as M 13 (SQM 20); M 11 "in two parts", found it only in my second attempt

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
