Thanks Dennis! We had some spectacular seeing on a couple of the nights (sub-two second!) which definitely helped on the core detail.

The 32 hours isn't quite as impressive as it sounds... after the first night, I just have to uncover the scope, wait for cool down, start imaging, do the flip, and go to bed. Feels like cheating

It's hard to find a better picture unless with a large scope.
I probably would have taken some short exposures at 1x1 binning just for the bright stars
& copied & pasted them into the pic to reduce their sizes.

Thanks Allan! The excellent seeing didn't hurt either A few of the stars are clipped in the raw subs, but I did also take shorter subs for later HDR combining. I think I need to learn a few more processing skills first to manage them better.

Cheers Rick! Thanks for all your help & advice too... I think we could call some percentage of this your image too

Something has gone awry with stretching process and the stars - they look clipped.

When you end up doing the repro keep an eye on that early on to see what happened.

Greg.
Thanks Greg. The 3D plot of the stars look good (mostly non-clipped except for the brightest ones), but I wasn't able to deconvolve them to reduce bloat and compress their dynamic range (but it worked quite well on the small stars in the galaxy core). I'll have to learn a few more processing tricks over the summer. Any suggestions welcome!
