hello gordon
i see you have a lot of high end equipment which should give stunning results, there are a couple of things noticable in this image
i comment in the hope that they are taken as helpfull rather than criticism.
The stars have dark haloes around them, this is usually indicative of a sharpening process which has gone too far. If you are trying to sharpen the nebula then layer the unsharpened over the top and paint in using a layer mask the unsharpened stars, or layer the sharpened over the top and paint in the neb (my prefferred) treat the image as the sum of parts rather than applying a technique to the whole image. you might try some other techniques such as deconvolution again with the overdoing in mind. ( i dont think you used decon on this as usually it burns the star centres out noticably)
The background is a little noisy, this is usually a result of pushing the image to and beyond its limit, some noise is acceptable and this isnt horrid, however if you are trying to present the best image, then either process it less or collect more data, another technique for cutting down the background noise is to get a less processed image and layer it over the processed one, this time you need to apply a curve to darken the background of the highly processed one and as long as the less processd one has a brighter sky, blend as lighten.... this is fairly tricky to get just right and will take some practice. otherwise more data, the difference between 2hrs and 8hrs is huge
im not particularly familiar with the Scope you are using, but i asume F5 is not its native length, if so and its a bright target then given the gear you have you should get in closer for more detail.
again these comments are not intended to be critical, but to point out how you can improve what you have already achieved.
kind regards
clive
