Given the cr*p weather I thought I would play around with some old data. This image is basically a photomerge of STL6303 and STL11000 data hopefully incorporating the best features of each. You can just see part of NGC4945A at the top. The STL11K image was a LRGB 180:100:100:100 all 1x1 and the more recent STL6303 image was 100:40:40:40 with the colours binned 2x2.
Nothing of consequence but I felt like posting an image.
Nice image Steve. The background looks black clipped though.
I don't know if you use CCDstack but you have to watch it as the auto button on DDP will black clip data a little bit. You can see it with the latest version which has a histogram available now.

Thanks Greg. You could well be right about the clipping. This was just something I knocked up in under an hour and probably didn't pay enough attention to what I was doing.
Actually it's a technique I picked up from Ken Crawfords tutorials

I just had a look at his digging out the details one. I usually do a very crude approximation of what he does (creating a sharpened image, covering it with a layer mask and painting in the bits I want to keep) but I didn't think this image warranted much playing around with.
