Thanks!! Look forward to seeing how you do it in Pix!

Before and after, Pete.

Background, flattened.

H!

That looks good! Are you going to share the secrets?

Thanks so much.

I'll write in the morning. I woke up as I wasn't feeling well and thought I'd have a play.

That was literally 1 minute of work, after 2 minutes of experimentation on a preview.

I don't have a DropBox, but, I'll upload the final TIFF for you on my webspace for you to further play with.

Peter, the resolution is great. So too is the star colour. I really like the overall look of the image.

There is indeed some noise in the background but you could simply collect more data rather than trying to process out the noise. Noise control really ought to be the last resort. A couple more hours would give you the noise control you would need.

There is also an odd looking mix of blue and black blobs in the back ground. However, both of those really are minor and I would only collect more data is you wanted to eliminate the visible noise altogether.

In my opinion a nice looking rendition of this globular.

I agree with Paul, re: more data for less noise.

Also, the coloured blobs are large scale noise, which seemed to be taken care of by MMT.

Hi Paul, (and H.)

I cannot disagree with you about the benefit of longer imaging time. However, in this case I was borrowing the TAK TOA-67 from a generous friend and I now have ordered my own. So, I'm out of luck for getting more data for the time being. Processing will be the end game now.
