M5 from 24 May 08       #2552951 - 07/31/08 05:01 PM Attachment (30 downloads) Edit   Reply   Quote Quick Reply   Processing some images in my backlog of images to process... This is M5.. I was running out of time before this slipped behind a tree. I had a clear night on the 24th of May (I remember it as a particularly transparent one, 4/5) so I figured I'd image some globs with the 8" SCT. In a hurry, I took a few subs at ISO3200 (gulp!). Really noisy result, most of my processing time was spent removing the noise M5, Taken 24 May 2008 Stack of 6 x 30 sec subs, ISO3200 Canon 40D through Meade 8"/200mm SCT w/0.63x reducer, f/6.3, 1260mm focal length Autoguided with Philips Toucam Pro 840k webcam and Guidedog software Focus and camera control with EOS Utility Calibrated and stretched in Iris Final Processing in Photoshop CS2 with Noel's astronomy tools, GradientXTerminator, Noise Ninja and FredMiranda.com's Intellisharpen II Full frame image: -------------------- LX200 8" classic, f/10, Meade eq. wedge, .63x FF/FR Canon 40D and 5D, unmodified Canon EF 300/2.8L IS, 400/5.6L, 135/2L, 50/1.8, 85/1.8, 35/2, 24-70/2.8L, and Peleng 8mm fisheye Orion Apex 102mm (4") Mak-Cass Pimped out with accessories and bling My DSLR Astrophotography Webpage and photo bucket with full equipment list Post Extras:       Andrew Welsh Carpal Tunnel Reged: 03/28/06 Posts: 2483 Loc: Rochester, NY Re: Backlog..

The lesson for today's class is to not image at ISO3200! I'll give it a go with the horiz/vert banding removal routine.

M5 from 24 May 08 [Re: Andrew Welsh]       #2553654 - 07/31/08 11:41 PM Edit   Reply   Quote Quick Reply   I always run the Horizontal/Vertical Banding Reductions first. Then the Color Blotch reduction. Finally, Space Noise Reduction. Usually I do a Curve or two before any noise reduction. But as you said, with a bright cluster I'd shoot at a much lower ISO. -------------------- "Is that boy on the moon again?" - Gumby's Dad.

Eric, I do the horizontal banding first as well.. then I run space and/or deep space.
