400 Herschel Objects
data by A.J. Crayon and Steve Coe

Observations by Steve Coe using a 13" f/5.6 at 100X, unless noted otherwise. The other telescopes I have used over the years are a 4.25" f/4, 8" f/6, 8" f/4.5, 12.5" f/6, 17.5" f/4.5 and an 18" f/6. All these scopes are Newtonian in design. The poorest nights on which I have provided observations are 5/10 which means that the Milky Way is just visible and stars are seen to about 5.5 magnitude naked eye at the zenith. Most of the information is from nights I have rated at least 7/10 when the Milky Way stands out clearly and stars to magnitude 6.0 are easily seen. Some of my most cherished observations are from 9/10 and a few 10/10 spectacular evenings when the Milky Way blazes overhead, Zodiacal Light is a brilliant cone standing on the horizon and stars down to magnitude 6.5 are seen naked eye.

This list of Herschel Objects is from the book Observe the Herschel Catalog. All of the information in this listing comes from the Saguaro Astronomy Club Data Base version 7.2. The columnar information follows normal acceptable information.
