A less often imaged galaxy cluster

As far as I can recall this is the first time I've ventured into the constellation of Telescopium. NGC 6868 is the elliptical galaxy at the centre and the brightest in this little cluster (magnitude 10.6). The most interesting looking galaxy is of course the spiral NGC 6870 below it. The second brightest is NGC 6868 over to the left which owing to my poor composition skills I've managed to partially chop off. There are lots of smaller galaxies in the field.

Cheers

Steve

Steve, that's gorgeous.

Your background is so clean and noise-free that you can stretch the faint bits about another 50%, which brings out rather more of the beautiful spiral. You can also up the saturation without any risk of colour noise. Statistically, the colour is spot-on.

Lovely work.
Best,
Mike

Thanks Mike. I must have done a better noise reduction job than I thought.

Nice one Steve! I love galaxy clusters. Colour might be a touch warm?

Thanks Lee. Yes the colour is too warm. I've hopefully corrected that now although I'm tempted to go back and do a full reprocess.
