Waiting for clear skies, I am posting some old images I took with my Sony A7R mirrorless camera and the AltAZ mount.

This is a heavy crop (like a 25% of the whole frame) and you can still see the star trails even for those 60s exposures. While the stacking software takes care of the field rotation by aligning the images, it can do nothing about the rotation occurring during the exposure = star trails.
Seeing those images made me realize that the AltAZ mount was a poor uninformed choice and I need to get an equatorial one.

You can notice also all those stars - way too many - maybe my camera is to blame for this? I thought an astro camera might help with this and that's how I decided to get one (ZWO ASI294MC).

Any advice on improving future shots of the same nebula please?

Thanks
