There is less of that salt and pepper colour noise that plagued your previous images with Brad's setup, and while it isn't bad there appears to be a slight red gradient..?

Overall a great vista

Interesting to compare your image with an image I did with the inferior optics of a 12" SCT at 1500mm FL (poor guiding though, so had to work on the eggiest stars ). The RC is an order of magnitude (or two?) better for sure!

Cheers Mike. Have to say you're rendition is actually quite good considering the optics and all. As I mentioned in the original post of this image, I was actually surprised by the lack of noise and gradients in the raw data. Some noise still exists in the output presented as I've yet to get around to cleaning it up. I'm going to reprocess the image once I've acquired more luminance data. I really think there is more to this galaxy given ample exposure time. The nucleus is rather bright so its an interesting object to process. Thanks again for your comments.

But seriously, that is a nice image. Very clear and highly detailed.
Thanks Ken. Quality optics and shooting the luminance when the object is high is the key to sharpness. Once you've got reasonable data, its easier to produce a great image through processing. Thanks mate.
