M101 A Pinwheel in the Universe

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.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
