I had already taken these 2 subjects (M101 and M51) with the Nikon D200 and I wanted to repeat them with the ZWO ASI294, I am quite satisfied but I think that for these galaxies the quality of the sky of Colle Petroso is not the best, I will probably try again from Monte Labbro and maybe lengthening the pose a little ... :-/

Hello Renzo.
It's a great result, you pulled out the parts It has perfectly.
I do not know if you have reduced the C9.25 and / or you have done a pushed binning, in any case it is a very difficult task anyway because at the focal ones with the 294 you are in extreme oversampling, and even if you breathe 2 meters from the frame, you have driving problems ...
So double compliments.

Thanks Giancarlo, the 9.25 was reduced to f / 7 (1645mm), for the guide I used a focal length of 600mm and with QHY, since it has the pxl from 3.75 I return right right, then also the AZ-EQ6 behaves very well, it gave me some problems only in the presence of strong gusts of wind but the other night it was rather quiet and with the AHT tripod you travel great ... :-)
ps: the photo is cropped by 10% ac(linear).

:-) :-) Thanks 1000 for the appreciation, but in truth those proportions were not intentional but caused by the somewhat short focal length for that subject.... ;-)
