Messier and Herschel with NGC numbers

I hold Honorary Messier Certificate #404 for observing all 110 objects cataloged, completed in 1978. I began logging observations of the Herschel 400 objects on 27 February 2000. My official announcement of this undertaking was made via e-mail to members of the Denver Astronomical Society on March 13, 2000, in honor of the two hundred nineteenth aniversary of Sir William Herschel's discovery of Georgium Sidus (Uranus). I logged the 400th object on May 19, 2002, and received certificate #246 of the Herschel Club on July 1st, 2002. My OBSERVE: The Herschel Objects is ©1985 Lydel Guzman, Brenda Branchett, and Paul Jones; published by the Astronomical League. This has been an excellent exercise in organization.

Yellow NGC numbers are in both catalogs

Green NGC numbers are "overlooked objects"

Blue IC numbers are Index Catalog objects

Names are from the Observer's Handbook, "overlooked", or common sources

This combined list is organized like the Messier List, breaking down the Spring and Summer seasons.
Introduction | Part I: Winter | Part II: Early Spring | Part III: Late Spring | Part IV: Mid-Summer | Part V: Late Summer | Part VI: Fall | Addendum A: Miscellaneous | Addendum G: Globular Clusters | Addendum S: Southern Extents | Solar System

* - 10,11,12-V, 41-IV

**NGC 6603 is only part of M24, and often (incorrectly) identified as the NGC number of that Messier star cloud.
