WHOA!! 8O Talk about BRIGHT!
Sweet shot Rob! Wonderful wide-field, nice equipment!

Question: is it me, or do I see a lil' too much BLUE?

Keep'em coming!

Lot of detail there and color. Stars are tight and the FOV is large, nice picture.

Sweet shot, Rob! Great FOV! As Ivan mentioned, there seems to be a bit of blue in the brighter central region of the nebula. There also seems to be a rather abrupt transition in brightness/blueness from the bright central region to the dim outer regions. Now, if this is the way the data came out, that's perfectly fine then. But if this was a result of selective processing, you may want to look at that a bit.

Now, the above is a nit - just something I see that sorta leaps out at me. I'm almost afraid I'm developing a critic's eye the way I look at astroimages. I just hope I don't turn into an outright critic - finding something to gripe about but not knowing how to fix them myself!

very nice job, Rob!
very deep color!
