Thank you very much @molometer
The good thing is, that the stacking software does the most thing automatic. So, in the end, the different panels must only be stitched with Photoshop and the image must be edited.
EZPlanetary was used to capture the video with the guiding cam and AviStack 2.0 was used for stacking.

I'm curious about your pictures and look forward to seeing them. :-)

Thank you very much for your kind words and thank you very much for your resteem :-)
