Necessity is the mother of invention. Observe the Herschel Objects, developed by the Ancient City Astronomers (ACA) of St. Augustine, FL, has been for years, the definitive, structured, certificate observing program that accomplished amateur astronomers could complete. In the 16 years that the program has been available, 157 amateur astronomers have completed the project.

In the Pacific Northwest, the Rose City Astronomers of Portland Oregon has seen quite few of their members actively working on all of the available observing programs of the Astronomical League. The Messier Club and the binocular programs provide a great introduction to building the navigational skills, and developing the observing and note taking skills necessary for finding deep sky objects. The Herschel 400 has been the logical next step, and many members have worked their way through and completed this challenging project. However, all too often, the excitement of logging object No. 400 and receiving that certification has been dampened by a "what's next?" letdown.

This letdown at the end of the Messier program prompted the Ancient City Astronomers to develop the original Herschel 400 program. And the same type of letdown has now prompted the Rose City Astronomers to develop the Herschel II program. The ACA were supportive and helpful, giving the RCA their blessing and good wishes, and when the news leaked out, developers Candace Pratt and Carole Cole started receiving phone calls and e-mails from all over the U.S. Clearly, there was a need felt by amateurs across the country. The developmental process took two and a half years. The resulting Herschel II program is a challenging undertaking for those observers already familiar with the night sky, navigational techniques, taking field notes, and operating telescope equipment.

There are 2,478 Herschel objects. At the beginning, the RCA selected 650 possible objects for the development team to hunt down and consider. 25 members of the RCA, and 5 additional observers around the country tackled the project.

Realizing the challenge of reviewing such a large number of dim fuzzies, the team selected a computer program to help with the search. They selected MegaStar 3.1 as the most comprehensive software to meet their needs, and developer Emil Bonanno of the Houston [TX] Astronomical Society graciously volunteered a copy. A 2-degree field MegaStar chart was printed and used by the observers to help locate each object. At the end of the two and one half years, a final list of 400 objects was selected.

The Herschel II manual includes the descriptions of the selected 400 Herschel objects in NGC ascending order. It also includes a planning guide with NGC numbers listed in RA order, to help in planning an evening's viewing session. The coordinates are Epoch 2000, with MegaStar 3.1 serving as the source for all location information, as well as magnitude. The "Criteria and Submittal Instructions" section gives specific minimum criteria to meet Herschel II certification. Instructions and forms for submitting observations are included.

Developing good field descriptions is a combination of several components: looking for the specific features in each object; observing minute detail in the object; and then writing an appropriate description. Several examples of observing forms are offered in this manual. You can use what is provided here or devise your own method. The observers in the gathering phases of the Herschel II program reported an increase in their ability to pull out minute detail as a result of using the "object-specific" questions on the observing forms provided.

The Herschel II program was originally planned for observers with telescopes 8-inches and up, but that seems to be a stretch. A scope with a minimum aperture of 10-inches will probably be needed to complete the whole program.

Technology continues to add many wonderful options for amateur astronomers. The Herschel II program leaves the choice of how to navigate to the object totally up to the observer, whether it be star hopping, geometric placing, stellar off-setting, right-angle sweeping, setting circle methods, or computerized locating programs. Accordingly, the certificate issued will include an alpha-numeric designation that will indicate "M" for a manual search or "DA" for a device-aided search.

The Observe the Herschel II Objects manual itself is one of the most attractive and well laid out books that the AL has offered. The book is 110 pages, spiral bound, paperback, with a handsome, dark teal cover featuring the Hubble Wide Field. The spiral binding will make it very easy to use during a night's observing session. Inside, the pages are a full 8.5 x 11 inches, with large, easy to read type. The best feature, aside from accurate descriptions of each object, is a selection of observing forms. These can be photo-copied and used for any observing project, not just the Herschel II. The price is very attractive, and the observing hints inside more than justify the cost of the manual, whether you eventually pursue the program or not. And it would make a great Christmas stocking stuffer for that astronomer in your family.
