Did you check the back cover for water damage before you got too excited? Silver Surfer #4 is one of those books where condition really matters, so take it to a shop and get an honest grade before you start dreaming about the sold listings. My rule with bin finds is to press it flat between heavy boards for a week or two and just leave the cleaning alone, because a lot of guys ruin a good book trying to fix a stain. Also make sure Dave was looking at ACTUAL sold prices and not asking prices, since those are two very different numbers. Either way a buck for a key issue with clean pages is a great day, congrats.

Man, I bookmark stuff like this and still never remember it either.

Boise backyard for 7 months and your brother in law tells you to skip the tracker? That is wild to me. Wedding photography and deep sky imaging are like two totally different planets, the light is so much brighter on a wedding day that he probably never had to fight noise like we do. Crank the ISO and take short subs is the classic bad advice that sounds right until you actually try it on a nebula. 200 frames at 15 seconds should have been enough data if the setup was right, so the problem was almost certainly the read noise stacking up on every single sub. A tracker fixes that because longer subs bury the noise under the signal, which is exactly why your first 3 minute shot blew the whole night out of the water. He wasn't being mean, he just doesn't know our side of it.
