M7 Open Cluster Closeup

Reshot this one. I was aiming for round stars this time, rather than the bananas I got with the last shot.

Collimation and autoguiding were much better. This time the stars look a lot less like bananas when viewed close up, however I think focus could have been sharper.

Scope: SN-8 LXD-75; MPCC; Autoguided; no fishing line.
Exposure: 42x30secs ISO 1600.
Camera: Canon 350D unmod.
