Between October and mid-December 2017, I did simple "deep-sky autumn observations", mostly with binoculars, which might be of interest to other beginners and are therefore described here.
My observations ranged between the coming Orion in the East to Hercules in the West. I mostly "hunted" for objects that can be observed with binoculars.
The following map shows approximately the sky area that I primarily browsed during my observations:

Observations started early and the sooner, the later it became in the year. At the beginning of November, I also observed after midnight with my binoculars.
All observations were conducted in Mühlhausen/Kraichgau (Germany):
In general, the sky above Mühlhausen/Kraichgau is "light-polluted" and does not invite you to search for deep sky objects. This is certainly one of the reasons why I found some of the deep sky objects that I wanted to observe only sometimes or not at all.
|Observed Objects||Details, Remarks||Further Observations and Remarks||Devices Used||Eyepieces Used|
|October||GC: NGC 884/869 (Perseus Double Cluster)
P: Cr 399 (Coat Hanger)
|Several observations, both objects seen well||Only binocular observations (comparison of the new night glass with the old compact binoculars)||LT and TS binoculars|
|Nov 4||GE: M42/43 (Orion Nebula)
OS: Mel 25 (Hyades)
|M 42/43 seen in binoculars; quite faint due to almost Full Moon (midnight
until about 1 o' clock), 2 bright spots (stars and presumably the Trapezium)
glow in the nebula
Mel 25 seen well (after midnight)
|Only binocular observations (comparison of the new night glass with the old compact binoculars)||LT and TS binoculars|
|Nov 13||G: M 31 (Andromeda Galaxy)
GC: M 13 (Hercules Globular Cluster)
OC: NGC 884/869, Mel 20 (Perseus Cluster), M 45 (Pleiades), Mel 25, M 34, M 39, M 11 (Wild Duck Cluster)
P: Cr 399, St 2 (Muscle Man)
|NGC 884/869 with "ring" (at its end is supposed to be St 2)
St 2 (muscle man) located at the "ring" of the double cluster: shape not recognized as such, but seen stars...
Cr 399 found via Albireo
M 39 at Deneb, at the upper left end of a transverse Ypsilon shape (TS)
M 11 Wild Duck Cluster, probably not seen at the bottom of the swan
|100P: Mel 20, NGC 884/869, M 34, M 39||LT and TS binoculars, Heritage 100P||Not documented|
|Dec 12|| GE: M42/43
OS: M 45, Mel 25, M 35
|M 42/43, M 35, M45, Mel 25 seen well, M 35 not so good...||LT and TS binoculars|
