Thanks Jeanette for placing my image on your desktop.

Some of the stars look a bit funny, like they're casting shadows. Is it a mismatch between channel alignments?

All in all, I like it; quite unique.

Hello Humayun. Due to flexure in the camera/ optical set up I have left the stars out of the sharpening process otherwise the stars would have a decidedly stranger shape. Maybe that is what you are observing.

But maybe a better processing would do justice to the data you have collected.
Regions of the galaxy have not been selectively sharpened or blurred. The higher contrast central regions are more responsive to sharpening compared to the lower contrast areas in the arms.

I have never heard of image scale being too large for data unless you are trying to hide flaws in the image. Image detail is a function of the scale. I'm not prepared to sacrifice detail by going to a lower resolution.
