Took another stab at narrowband imaging under a full moon:

I suspect I could get more of the reflective nebulosity w/o moonlight? I was also having dew problems with the scope all night. No problems w/ ATIK CCD.

Enjoy!

Nice work there bwa... the outer OIII shell is starting to show nicely.

I took another look at the image this morning (after a few hours sleep) and don't like the background color or the fact I probably over sharpened the image... A bit of reprocessing required!

Took another run at processing this image:

Hi Brian, i like the reprocess, a much better result. The original had an overall magenta cast which is not present in this image.
This version is not as over sharpened as the previous also. Good job!

The second run of your image processing is definitely the better one; the first one was indeed a tad too much sharpening...

Beautiful image. Nice image scale as well.
