Got a Big Dob? Take a look at our newest Telrad Finder Chart - the Herschel 400 Telrad Finder Chart.
Includes the generally accepted "best" 400 objects selected from the Herschel 2500 for the A.L. observing list. These are significantly dimmer than the "Best" 300 and require a larger scope. For really good views a 10" or larger under dark skies is recommended. It has about 120 objects in common with the "Best" 300. 43 pages.
All of our Telrad finder charts have all pages completely laminated for moisture protection. They are comb bound and can be reopened so that we can bind in Alignment star charts, Limiting Visual Magnitude Charts, and Meteor Radiant Charts if purchased at the same time. This is done at no cost if it is requested. These books are an inexpensive way to "Go Deeper, See More"
Our charts will also work with Rigel finders which have only the two center circles (0.5 and 2.0 degree), They also work reasonably well with a normal (or even better, correct view) finder scope. Since they have the NGC/IC designations for the objects, they can also be used as a guide for a GOTO scope.
Appropriate table of contents/index to make finding constellations and objects easy. They are well designed, organized and easy to use. The catalog names are retained and cross referenced with the NGC designation. The tables give enough information to be sure you correctly identify it when you see it.
All of the charts are organized in the same way. They run from North to South in 4 groups, (0-6h, 6-12h, 12-18h, 18-24h). Once you are in a section of the book, you can normally stay in that area all evening. The table of contents include a small set of maps to help you remember constellation location as well as an index of where a constellation is located in the book.
