Re: [APML] New NGC 7331

Tony,

Absolutely stunning! The arms are very detailed and the image is sooo
smooth. Nothing here looks artificial to me.  Congratulations on another
masterpiece.  Can't wait to see this with color.  But I'm wondering, is
this art or science <vbg>?

What I wouldn't give to spend an hour or two (or three or four) looking
over your shoulder!  Care to share some of the technique?
