NGC6752 and friends from Astrofest

[that_guy (Tony)]

Many cloudy nights at astrofest with only 2 nights worth imaging from when I arrived on the Tuesday. I'm trying to focus on trying to get more data for a single target as opposed to many targets with few data. Also wanted to try something new with a popular target but with a different framing. Focusing more on the galaxies in pavo surrounding the globular cluster rather than the cluster itself.

Theres some pretty nifty galaxies within the area, two of which seem to be an interacting galaxy that looks like a little love heart. Theres another diffuse (dwarf?) galaxy PGC2815824 that looks super faint and irregular in shape.
I ran the whole thing through PI image solver and image annotation script to get some catalogue names on the brighter galaxies.

Also the first time doing a full LRGB run with the ASI1600MM pro!

Acquisition details:
77x 5 min L
20x 5 min R
26x 5 min G
22x 5 min B
All shot at 0 gain (another experiment to see if theres much difference in shooting more shorter exposures or fewer longer exposures at lower gain, results are... inconclusive.)

Astrobin link for full res here and here's the annoated full res

Thanks for looking!

i think lowest practical gain is 65...

I would have googled it had I had internet at Duckadang aha. Thanks for letting me know Diego. Something to change next time I'm out.

Always like this framing of this grouping Tony, nice job. Cool to see a glob with some detailed galaxies in the same field

A very sensible approach acquiring more data on a single area. The grouping of galaxies toward 7 o'clock is excellent.

Two tiny things that could be tweaked: there is misregistration of the R, G, and B across the image, with B always a few pixels too far toward the top of the image, and generally, the red and especially the blue are a bit too strong so the globular looks too blue and the stars have a slight magenta-blue look.

Those are just processing tweaks. Other than that, a superb result.

yeah something happened during the star alignment process that made weird stars. i think i need shrink some stars in one of the channels to better line it up. I'm still getting used to processing in LRGB. OSC was so much simper

nice framing - might look st that for the future. you got a great result
