47 Tuc

Winter has meant it's been a while since my last image that's been remotely worth posting. In fact, it's been so long, I even had an automated email from Astrobin enquiring as to where I'd gone!!

About 4 hours L and 4 hours total RGB on 47 Tuc from a dark sky site in South Australia - not great seeing so tried to do my best with the data. ZWO ASI 1600MM-C and RC8 mounted on an AP Mach1.

Interestingly, I noticed the galaxy PGC 1536 (ESO 50-10) lurking in the background (near the top to the right of centre).

Full res on Astrobin here.

Comments welcome.

Thank you so much, Andy.
Yeah, the RC8 was a bit tricky to collimate, but seems to perform well once dialled in.

My not-quite-3-year-old daughter came and sat next to me when I had your image open and she immediately said "Aww that's beautiful!" I have to agree, that's very well done, Paul, especially considering you said seeing wasn't great.

That's pretty spectacular. Very nicely processed, you kept the dazzling brightness of this object without blowing out the highlights.

The star colours are probably very accurate as Globs are usually older yellow type stars.

Thanks Lee

My teenage son just made a sort of incoherent grunt when I showed him

Thanks Greg. Yeah, I tried to push the core a bit to make it stand out but not blow it too much.

A fantastic, beautiful image of 47 Tuc, Paul. That has to be one of the best images of the globular that I have seen. Well done!

Great resolution Paul, colour looks good overall but the red stars appear slight pink to me. This might be related to the same issue as with NGC247. I wonder if there was fine dust in the air on those nights?

Thanks Paul. You may well be right. There was some bad seeing those nights - thought the 47Tuc data was taken earlier on in the evening when the seeing was better - but could also have been some dust around.

That’s a great shot Paul. The colours are good and yellow as they should be for a globular cluster. Good acquisition and processing have given nice resolution almost all the way to the core
