Ahhhhhh, memories. When I got my first telescope - a C-8 (orange - the best color) back in 1980, I also purchased Ve hrenberg's Handbook of the Constellations. 1950 Coordinates. Much smaller about 8" by 12", w hite stars on black background. On the right side was the constellation and on the left side was a whole page of objects and their ra/decs to find within the constellation. Good for northern and southern hemisphere. Am sure it is not nearly as detailed as your's Chuck, but it certainly served me well. The binding is held together by duct tape (bless that invention), but the pages are in very good shape. The Tirion is to big and cumbersome. BUT, those old fashioned paper charts are well loved and appreciated at private observing sessions The glow from lap tops, ipads/pods and such are NOT appreciated. Tried it once with my Sky program -gahhh, the glow blew the night vision to smitherins. .
