Kurt, Some years ago I used Burnham’s book as a source for double stars to put together a list of doubles by constellation. Then I found some neat websites, as you have, such as the Belmont society and others to add to the list. I don’t remember what all my criteria were but some thing like the main start had to be brighter than 7.0 and the companion had to be brighter than 9.0 and the separation had to be larger than 3.1”. I threw in some exceptions figuring that I might want to check out a few tougher ones at dark site. This is what I had for Hydra: 27Hya (companion)(Spect G8, F5) 09h 16m 54s -08 45' 47" Mag 5.5 & 4.8 Sep 229" P.A.211 Opt Mag 4x N Hya (Spect dF6, dF7) 11h 32m 29s -29 17' 07" Mag 5.8 & 5.8 Sep 9.5" P.A.210 Opt Mag 79x S 651, HR5120, SAO181790 (Spect A3, A5) 13h 37m 03s -26 31' 02" Mag 5.8 & 6.7 Sep 10.2" P.A.190 Opt Mag 74x Those may suck. I don’t know, I haven’t checked them out yet, but it is a sample of the way I decided to list things. I also updated many of them with the HIP catalog numbers. I really should update my planetarium to default to the SAO list I guess. I have had too many other things going on to get to that just yet. I made charts of each constellation with the telrad reticle marking each pair’s position. I had to update the RA & Dec because since Burnahm’s time things have really changed. In some cases I included a picture mostly from the Belmont Society. I put it all together in HTML format on a CD. The link to "Spect" is a link to a separate page that reminds me what G8 really means. I find that spectrum is so variable among different lists for the same thing that I don’t put a lot into listing spect anymore. In many cases when I went out to actually look at what I had listed, some fell woefully short of my expectation in my ability to either find them or separate them; but that was half the fun. I found this to be a fun winter project though. Now that I have gotten into astrophotography I would like to image them. I think I would go slightly out of focus to enlarge the stars and see the color better. Then I will include them in my CD. That is a long term project though. Anyway, having gone through the process, I know the work you are doing is time consuming and not a small task. Once I get to the upside of the learning curve of astrophotography, I plan to get back to doing some doubles, so I am saving your posts to add to and improve my list. Jim
