Yeah, I'm quite new to it also. I don't always do RGB so I've taken a while to get around to trying binning them

I do get some random blotches over my images: dark, red, green, blue, luminance. Using reduction frames from the same night as the imaging run certainly helps. With all my "pretty picture" images (ones I don't care about the scientific aspects/accuracy of) I zoom in to about 300 pct in photoshop, and go over them with the clone tool, removing such artifacts.
With this paritcular object I had to do that quite a bit, because it was a rushed process of the images. Better processing of the images would have meant I'd end up with less specs, but I didn't have time.
I haven't had time to go and re-do them yet either. (and only have time to write this because I'm avoiding things at work
, but can't do my processing at work!)
