    According to your guidelines in your artical I have  processed 47x 90 sec Lights , 9×90 sec Darks and 25 Bias.

    During the process I really noticed that Flats are essential.

    The eventual result is a lot better than stacking with DSS.

    Mabula thanks a lot for your help!

    Excellent @hansvanoverzee ! Glad to help 😉

    Indeed, flats will help the result a lot. So focus on creating good flats.

    Another focus point would be to improve tracking of the object. You’ll notice the noisy stripes in your data. This could be a result of not using a guide camera. So only using the mount to track the object. For each exposure, the object is slightly shifted in one direction (declination drift most strongly) causing the stripes. Guiding and /or dithering between several exposures will reduce this significantly.

    Let me know if you need more help 😉
