Superb details and dynamic range. One for the poolroom.

Very nice image for 2 hrs worth, prefer the colour balance in Image #5, though #2 is a nice palette too.

Thanks Marc,
I was more pleased with what Startools could do with NB OSC data to create some neat Bi colour channel blends, than the actual quality of the image itself. If I remember rightly guiding was poor that night so stars weren’t exactly tight and I did have some coma in the corners before I sorted that out weeks later with a spacer , definitely not my best Carina but stoked about the creativity of the end results
No pool room unfortunately, a few get hung up around the house down south
Cheers
