Reprocessed Images and Something New

The recent lousy weather (for astronomy) has kept me indoors for some time now, and when that happens, I sometimes dig into the archives to see what I can reprocess.

Messier 27, the Dumbbell Nebula, was the first thing I imaged with the Epsilon-200. For some reason, I recorded all of the subs in JPEG format instead of CR2 (RAW). Regardless, I was very happy with the original image at the time. I've learned a few tricks for reducing noise, though, so I thought I'd take another stab at it:

For comparison, see my previous post of Messier 27.

I've never been very happy with my image of Messier 17, the Swan Nebula. Like my M27, I only collected JPEG images. The images were very noisy, which made it difficult to bring out the fainter details of the nebula without swamping the rest of the image in colored streaks. A program like Neat Image can be your friend in those circumstances.  Here is a redo of M17:

And, finally, here is a "new" image of Messier 8, the Lagoon Nebula, that I imaged some time ago. I think this is the first time that I've posted it in a public forum:
