From the end of February 2019, I conducted simple deep sky "winter observations", which might be of interest to other beginners and are therefore described here.
List of observed deep sky objects (the links lead to pages describing the DSOs):
I mostly selected my observation objects on the basis of my previous observations.
I initially restricted myself to the sky region around Cancer, Gemini (Twins), Orion, Auriga, and Taurus (Bull) because these constellations were more or less in the same direction for me (southwest to south).
The following map shows approximately the sky region that I primarily browsed during my observations:
Click the map for a larger version - it opens in a new window. The deep sky objects that I tried to observe are indicated by red dots.
The observations of deep sky objects started after it was sufficiently dark.
All observations were conducted in Mühlhausen/Kraichgau (Germany):
The observations started nearly a week after full moon so that the moon did not disturb my observations any more.
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.
