Hi Stefan -

Excellent image - I think the ring minima is a real observation - it appears in many images of the comet, with varying degrees of contrast depending on the processing.

great work!

Holmes 7/11

Nice work, Stefan - it is certainly getting lopsided. Holmes now seems to be settled into the sights of large CCD cameras.

best wishes,
Alan

Nice lunar images. I have a feathertouch dual speed focuser on all my scopes - I find it works very well for imaging with a light weight camera and is an especially helpful for a very fast focal ratio scope. I think many imagers prefer a motorized focuser. There are a lot of FSQ users out there - I would check the user groups to see what folks have chosen for this scope.

best,
Alan
