Nice Anthony,
I like the details that are evident in the Ha data.

Robert,
Cool image. Who would have thunk you could do it in 45 minutes. Of course if I was faced with 25 degrees, I would have done it in 30 minutes.

Sharpless 187

Posted By Jim Thommes
Thanks folks for the comments.

I think a general theme of the comments was on the richness of the starfield (and bright stars). There was some star bloat as well due to the stretch.... I think the stretch along with some strong saturation tended to bring out the characteristics of the field of view. I was happy that the data supported the agressiveness of the processing - given the short exposure.

Flare from Compressor/Field Flattener

Posted By Jim Thommes
Alex,
I have a C8 and I use a Celestron 0.63X reducer/corrector. I have not experienced these flares. As Charlie says, I find the distance to image surface critical for star shapes, but that's about it.

Monkey Head

John,
A very fine image. The OSC's RGB image catches that reflection part on the right side of your image. It's hard to get this with an Ha for luminance.

NGC 7293 - helix up close

Posted By Jim Thommes
Nice close up of the Helix Charlie. I like the little galaxy in the upper right. This doesn't show up nearly as nicely in the wider field images.

Robet,
That's a really nice image. And only 40 minutes with scaled darks. Nice job.
