My best ever galaxy cluster

Geeday Scott,

That's a fantastic shot. I love those faint galaxies in the background too! Have you used STAR Atlas-PRO to determine the faintest galaxy on your image ?

If you want to use IRIS to get rid of those hot pixels you should type "FIND_HOT COSME 80" in the IRIS command window when the dark master frame is loaded. This command will find hot pixels with a value of up to 80 (you may need to increase this value to get rid of really hot pixels ).

Anyhow, again - what a great shot!

That's fantastic Scott.
Well done.

Thanks all
Ive seen that IRIS command but wasnt really sure what to set it at. I will try 80 as a starting point now, and use SAP to check some galaxy mags.

Ive managed to identify one galaxy called PGC566825 B Mag 17.88
another PGC566047 B mag 18.53 some other faint ones in the high 17,s in magnitude.

Wow! I missed this thread before. Gorgeous. Mindblowing thinking about what I'm looking at, how far, how grand, and all brought to us not by some sophistimacated multi-billion dollar space agency, but Scott and his backyard. Thanks Scott!

After a couple of days processing to get rid of some light pollution gradients...

Taken with 8"LX200GPS @ f5. Sbig ST-7XME, autoguided.

Thanks everyone. Id thought Newcastle too light polluted for decent galaxy imaging, but thanks to digital technology anythings possible
How dark was the sky when you took your image Stuart?

Here's the luminance sub before I removed the gradient, judge for yourself...
