M1 But With An Equipment Question

Posted By Joe McBride

If it was coma or field curvature I would think that the stars would be pointing away from the center (sweet spot) of the field. Your stars are circling it...at least on the bottom of the frame. Here is a shot I took of M1 a while back and the stars at the edge point toward the center.

Tiny M108 and friends

That is a fair amount of detail for the scale. The star at the top middle left looks like it has a couple of galaxies around it. I wonder if it is hiding a small cluster??

Nice Peter. Color is a little flat for me but excellent detail and processing.

Mount for Astrophotography?

Posted By Joe McBride

I have a CG-ll (pre G-11) now going on 14 years and I am happy with it. It will work in sub zero F temps just fine and still carry a decent payload.
