Ended up with just over 13 hours of data on this shot - 262 x 180 second exposures.
Image has been cropped and was taken using a Celestron RASA 11" coupled with an ASI 071MC Pro camera.

Looks good Graeme, has a nice glow to it ...is there a little vignetting there?

That's excellent Grahame. There's a glow around it. I haven't seen that in other shots. What is it?

[mswhin63 (Malcolm)]

Nice shooting Grahame, I hope to make it one of my next targets if possible.

Cheers Mike! I suspect there were high clouds at some point through the imaging session - while i filter within pixinsight using FWHM and Eccentricity values I haven't figured out how to quickly check and remove images affected by cloud (less opening every image and looking manually!!)

Quite a respectable Helix there Graham.

Have you tried the Blink process in PI? It is handy for quickly checking a large number of subs.

Clear skies,
