Antennae Galaxies NGC 4038/9

[Geoff45 (Geoff)]

This image combines data I took in 2016 and, more recently, at the April new moon this year. Seeing was never particularly good and there were problems with a star flare--you can still see some signs of it in the processed image. Quite a lot of data hit the trash can.

That's a nice shot Geoff! I might try it one day.

[Atmos (Colin)]

Still a result to be pleased with

[Placidus (Mike and Trish)]

That's truly excellent, Geoff. The faintest features are there. The detail in the core is great, and the handling of colour is beautiful - bright star colours but clean background.

Well done.

[RickS (Rick)]

An excellent result, Geoff. Love the colours!

[Joshua Bunn (Joshua)]

Nice one Geoff, really liking those colours!

[gregbradley]

Very nice Geoff. A few out of field bright star flares from the left side are impinging a bit though. Does your CDK have all the baffles that seemed to get developed later on? Mine largely stopped doing that with the baffle kit.

Greg.

Thanks Colin. It did come out better than expected when I was processing

Thanks Rick. I found that the arcsinh stretch in PI did a very food job on preserving the colours in the RGB image

I did fit the baffles, but it didn't solve the problem completely but the was an improvement.

Thanks Mike. Colours are always a bit of a gamble--you try this and that and they look crap then suddenly something happens in the bumbling around and great colour leaps out.

I also like the colour, seeing can be pain though.
