Description

Mein erstes Bild 2019 ist die Pinwheel Galaxy.
Ich schenkte ihr in 3 Nächten jeweils die zweite Nachthälfte.
Momentan probiere ich die ASI weiter aus und belichtete in den 3 Nächten mit Gain 0.
Doch leider habe ich bei Gain 0 Streifen im Bild. Ich weiß leider nicht warum diese entstehen.
Vielleicht muss ich wieder aggressiver Dithern um die Sreifen weg zu bekommen.
Wisst Ihr woher die Streifen kommen und wie man sie bekämpfen kann?
Die Nächsten klaren Nächte werde ich die ASI bei Gain 75 ausprobieren.

English:

My first picture of 2019 is the Pinwheel Galaxy.
I gave her the second half of the night in 3 nights.
At the moment I continue to try the ASI and exposed the 3 nights with Gain 0.
But unfortunately at Gain 0, I have stripes in the picture. Unfortunately, I do not know why these are created.
Maybe I need to get more aggressive Dithering to get the strips away again.

Maybe you know where the stripes come from and how to fight them?

The next clear nights I'll try the ASI at Gain 75.
