Also like to add the RGB image. 36 x 10 min exposures. Taken with AA80 triplet and QHY8 Pro. Captured in MaximDL and processed in APP / Pixinsight.

Thanks Richard. I'm always a little apprehensive of posting on the forum. :)

Don't be, although I am too.  But the criticism I get is well worth it.....  

This is a nice image, and one of a few targets that I actually prefer in mono.  You were lucky to get two clear nights last week - we had just one.  But I like this image.  However, I should say that for over eight hours of exposure, your Ha image seems to me to be a bit noisy at full resolution.  Is this due to the JPEG conversion or something else?

Yes the jpeg conversion has added some weird artefacts. I'll convert to tiff and see if that's any better

I used to use jpeg and it gave some funny results - now I use png - much better.  Tiffs are too big in my opinion.
