Thanks Allan. Not sure about professional but I tried to find a balance between fine detail and contrast level. The image could take quite a few iterations of sharpening before I got to this point.

Thanks Rick. I was surprised at the smoothness of the data after such a short integration time but then again it is very bright as far as galaxies go. With any luck I will get a night or two very soon.

Greg.
Thanks Greg. The luminance layer I did a fairly step stretch in CCDstack, and that resulted in a very high luminosity. Some selective medium curves and that gave it some pop.

Thanks David, I new about the line of gas and dust pointing away from the galaxy, but in researching the object I came across the arc of blue stars which can be imaged. So I am keen to see if I can get it brighter than just a smear at present.

Thanks Glen for the high praise but I am definitely not the RC master. I do acknowledge that I have learnt a lot about RC scopes and how to get them working well since buying one. Collimation is the key with these scopes and owning a tak scope for collimation is mandatory.

Thanks Mark, the central bar is not bad for the size of this scope. I think it compares fairly well with images from larger scopes.
