Custom Catalogue - "Best" Binary stars
Brett Laniosh
- The Coldfield Observatory list (http://users.compaqnet.be/doublestars) of 200 most beautiful Double stars - this includes colours and brilliant descriptions as well as a brilliant star rating system.
- Saguaro Astronomy Club Double Star Database (https://www.saguaroastro.org/sac-downloads) - This is a comprehensive dataset base of over 2100 binaries.
I’ve merged the Coldfield list into the Saguarto list and used a judgement call to select what I hope are the best 535 binaries as 2100 simply drowned the SkEye map view. The 300 additional binaries not rated have been given a rating based on the Saguaro description, so if it says "beautiful" I've given it a ***** rating for example. The stars without colours and no description have given a ** rating which Coldfield didn't use.
To make it easier to search the "best" binaries, I have included the constellation and the * rating in the name.
I've adopted the following colour system:
CoCo = Color Contrast, the star exhibits a difference in color
between the primary and secondary.
B:blue,
BG:blue-green, BW:blue-white, G:green, Gy:gray, L:lilac, O:orange, P:purple,
R:red, V:violet, W:white, Y:yellow but I have not included some of the more esoteric colour notes used by Saguaro.
For space reasons, the full descriptions have not been carried over but I do have these in the Excel spreadsheet I used to create this CSV. I recommended looking at the original sites especially the Coldfield one.
Finally, I had to convert the RA format from HH:MM.M to HH:MM:SS and tidy up the data so that the SkEye custom database would work. Thanks to Harshad for help here.
Even with just 535 objects, the map view is rather "congested". It would great (hint) if Map settings allowed you to change the Label opacity and Absolute scale and even colour of the custom database objects. :-)
