Want more? The Observer’s Handbook also includes Deep-Sky Gems, a seasonal listing of 154 nebulae, clusters, and galaxies compiled by noted comet hunter David Levy. Finally, if you’re a deep-sky specialist, you’ll also find lists devoted to double and multiple stars, carbon stars, open and globular star clusters, and galaxies. The Observer’s Handbook is an essential guide for amateur astronomers, filled with observing hints, a monthly sky calendar, and a wealth of data on solar system and deep-space objects. (The 2021 edition is available at MyScienceShop.com.)
For even more deep-sky lists, go to the website www.astroleague.com, scroll down to the menu on the left-hand side, and click on “Observing Programs.” This page describes the Astronomical League’s observing programs (featured in my March 2015 column, “Astronomical Game Plans”). From there, you can access an alphabetical list of the Astronomical League’s 70-plus observing programs. Pick one that interests you and download the list. You don’t have to be an Astronomical League member to do so, but if you are a member and complete a program, you’re also eligible for a certificate and award pin.
Rich Kupfer of Boynton Beach, Florida, has created a deep-sky list of his own entitled “The Elite 800 (A Deep-Sky Catalogue for the Discerning Visual Observer).” Designed for the backyard astronomer equipped with a moderate telescope, it was compiled from thousands of observations Kupfer made over the course of 40 years. Arranged alphabetically by constellation, it lists some of the most notable multiple stars, variable stars, carbon stars, asterisms, and deep-sky objects. The entries for some constellations are short enough to place on a single-evening list. Others are rather extensive (Virgo’s list covers nine pages!) and will need to be broken into multiple lists. Although “The Elite 800” was compiled with a 14-inch scope, many of Kupfer’s entries are within reach of smaller-aperture instruments.
