Just googled M57 images, and very very few reveal the "shockwave" detail you have captured here Dietz.
A truly amazing effort - thanks for posting.
Jeez mate, that is so good - I keep returning to your large version!
And those galaxies too!!!
I like!
Mike, the H16 is a wonderful item! though it holds a kodak chip...
I am a bit spoiled by the sony chips I worked with prior to the purchase of this CCD. (M25C and H9C)
