A few hours with the crab

Posted By Jim Thommes
Jason,
Great image!

Weird artifact. Its really hard to explain that one. And its in the Darks as well... And if it's in the darks, why doesn't it subtract out...

Is there a possibility there is a light leak in your camera? I think the ST2000 has an internal shutter for darks, right?

There ought to be a site somewhere to post weird imaging artifacts - particularly after they have been explained. I bet there are some real doosies out there.

Cocoon - IC 5146

Jim,
This is a really cool image. Great job.

The image looks well saturated online to me (but of course I don't have the original to compare). Be sure you are viewing them at the same pixel resolution on your screen - I think I may have seen differences at different screen resolutions on other images in the past.

Cocoon - old data, new processing

Posted By Jim Thommes
Tom,
I think I remember this image from before. I really like the framing with the dark nebula going from Cocoon to the opposite corner.

I like it.

What are the different techniques?

Rosette

Posted By Jim Thommes
Louie,
Great pic! I like the star colors and the natural look of the Rosette. Nice to see this object in full visable spectrum exposures.

Nice to hear about the site. Did you get a chance for a tour inside the AAT observatory?
