This was taken last year, but just recently reprocessed. Needs a bit of work still, but......my only shot of this one. 20min. ISO 800.

You got a lot for only 20 minutes Dave. You'll have to work towards hours for this stubborn one. It's a beauty though isn't it. How long were your subexposures?

As you get more and more data collected be careful in your processing that your black point doesn't get clipped. You don't want to loose any of those precious photons. Try to keep your RGB at 25, 25, 25 when you take a background color reading. I watch the CMYK reading to keep the K(black) at or very near 80 for a background that is deep but not pure black. In order for space to be pure black there would have to be zero light, too many stars out there for that. :D

That's a pretty good effort Dave - good polar alignment from what I can see of the image with my own eyes, and pretty good tracking it too it seems.

Yeeha!

Thx for that.... I believe those were no more than 2 min. subs since that was taken before I started autoguiding. I haven't gone back to that one since, but after looking at it again, I'll have to try it again soon. :cool:
