Deep, deep sky catalog?

Hi,
I have been observing deep sky targets for the past 25+ years thru a variety of scopes and more recently thru a 16" Meade Starfinder and then a C14. I have logged over 3,000 deep sky objects and I have observed basically all that is included in the "Night's Sky Observer's Guide" (vol 1 & 2).
I recently have purchased a used 20" Starmaster Dob which is an incredible performer and I would like to continue exploring the deep sky deeper than ever!
The issue I'm facing is that I am lacking a resource that would assist me in preparing the night's observation at these depths. I have the Hickson Group and Abell Planetary Observing Guides of Alvin Huey but I am looking for something more exhaustive. Since my log is an Excel spreadsheet, I would love to find out there a software that could interact with Excel and sort out data...
Any suggestions?
Thanks!
Francois

Not sure if this would help you but check out Messier45 dot com. Also, if you want some real challenges, join the Yahoo group DeepSkyHunters. They would enjoy reading about any observations that you can make of their exhaustive target list of asterisms, clusters, and nebulae.

Francois- This isn't software, but you might want to check out the very excellent book "The Arp atlas of peculiar galaxies" by Jeff Kanipe and Dennis Webb. It lists all of the Arps galaxies dividing the sky into sections from "A" to "Y" and gives visual impressions of the objects in scopes from 13" to 30" plus photos and drawings. Highly recommended.

The Saguaro Astronomy Club has an Excel database with over 10,000 deep sky objects:
