Really nice !

Thanks ! It is a great camera but its tiny pixels (2.4µm) are very demanding for the optics and tracking. Btw the field of view is much larger than in the opening post, here is the full picture

Thanks ! I don't have a light pollution filter as I am mostly interested in galaxies and I am not convinced that it would help for those.

Hi, A classic of the galaxy season, imaged from Paris' suburbs (Bortle 7/8) with my 8" f/4 newtonian and ASI183mm. I shot 220*60 sec luminance and used older chrominance data. Thanks for looking, Dan

Thanks Chris !  Luckily the camera was oriented with the right angle, Dan

Hi, here is an image from last night shot in my garden in the suburbs of Paris (Bortle 7/8). The most interesting object is a pair of interacting spiral galaxies in Canes Venatici, NGC 5394/95 or ...

This is Aiguille du Dru, not the Grandes Jorasses. Both mountains are spectacular though!
