M56 - a forgotten glob?

Posted By Jim Thommes
Charlie,
Nice M56. I think it's size discourages many images. I see you used adaptive optics for guiding - I think that helps (plus your optical system is as you say - a good match).

M57 again

Posted By Jim Thommes
Nice Charlie. I see the halo. H-Alpha should help, but yeah, I see the problems it can cause with the AO-8.

NGC206 star cluster from M31

I like it Mike. It stands as a cool image on its own - it would be nice as a mosaic section.

IC 1396 and vdB 142

Posted By Jim Thommes
Thanks for the comments folks.

About the 9 minute subs... Well, maybe this is a bit silly but with my Artemis I could do 4x4 bin test images. With the ST8300 I can only do 3x3 (and actually 9x9 but not 4x4). So I take a 3x3 test shot for 1 minute and say - "well this signal level looks acceptable." Then I figure if I want that level at a 1x1 bin for my image data, I need 9x the exposure time. Hence 9 minutes. Don't laugh.

LBN 442 and a piece of Sh2-126 in the 10 Lacertae

Posted By Jim Thommes
Tyler,
Cool image. And what a coincidence that I just shot this very same field! I think you got better data than I did - I'll use your image a guidance for when I process. I used the little Artemis camera and the little WO 66 mm refractor so that's my basis for thinking you got better data (with your AP130).

Sometimes I get mixed up with these things... I would have called this LBN 437. I would have thought that LBN 442 is up by HD214524.

Looks lik this image came out real nice, Maciej. The color looks great and the subtle backgrund structure came out great. Nice one.

The Running Man Nebula

Greg,
Very classy image Greg. I like the larger image - I didn't think it would help much with this field, but it is an impressive view over the smaller images.

Cool object, not so good conditions

Nice NGC 6823 Floyd.

Greg,
Such a nice spiral and your image of it is superb!
