Yes, another version of NGC6188, but not a wide field (this was posted in a different section before). It's taken 28km from Melbournes CBD, using Ha for the luminance, and a set of very short bin2x2 RGB subs to limit the prompt impact of my strong surrounding light pollution. Total: 161mins. Processing the colour layer was very difficult, involving a number of steps.
The scope being a CDK12.5, with STL-11000, Astronomik filters, on AP900GTO.
Excuse my tilt problem, I'll work it out one day.

That's a great closeup of this interesting area. Lots of detail everywhere. Out of curiousity, how short were your RGB and Ha sub-exposures?

Love it. Well done. The CDK is a nice scope right!
You have resolved that little cluster of stars at the top really well.
Your challenge is to do a 4 panel or greater mosaic of this object with your CDK.

Top notch Steve. Best ever. Incredible image scale and colours. :thumbsup::thumbsup::thumbsup:

Delightful image scale. Very smooth. Nicely done!:thumbsup:
Looks good Steve. The use of Ha and short subs have resulted in fewer and smaller stars than a normal LRGB image and this really helps brings out the nebulosity.

Ah yes, to AO or not to AO wasn't it..:question:
Has a great mystical dark feel, very noice indeed.
Tilt?..not noticable, tilt is a bugger to remove 100% especially with large sensors.

Great photo Steve.

Thank you for the positive comments, you have all been very encouraging.

60sec subs for RGB, but 20mins per Ha sub.
I did a lot of data processing to get the final result, and well beyond what you'ld normally bother doing. But the weather had been so bad, I just kept at it.

Lovely result, Steve!
