The catalogs I have show at least 34 galaxies brighter than mag 17 in your field Bert.

Some have ESO designations - ESO28-11, ESO28-12, ESO28-21, ESO50-10, and ESO50-5A - and the rest just PGC

I'm would be surprised if prices for slow selling big ticket items were listed. Most of the time the dealer doesn't keep them in stock so the price you pay will depend on exchange rates.

Kevin, I think I have to disagree. CdC says the asteroid to the left of NGC7724 is (21788) 1999 SZ5.
(21015) 1988 UF looks to be correct.

From the look of the RA graph I'd suggest the mount is too well balanced. This causes the worm to lose contact with the gear.
Try making it a fraction "east heavy". I know that's a pain since you...

If you mouse over the thumbnail it gives the name the uploader assigned the image - if they were kind enough to do so. The first one is "beyonce.jpg". Shame she has no taste in husbands.

A fine image Christian.
If you resize the 1600x1066 image to 1024x682 and then apply a moderate compression you'll get it below the 200KB limit. 86% works.
