Finished the candidate double star list. Over 150 entries! Splits from 0.5" to 424.5"! Magnitudes (of the primary) from 0.0 to 8.7. 46 constellations represented, from Andromeda to Vulpecula. About 3 targets per constellation. I think it's a good cross section of difficulties. I hope. From this, I'll try to whittle down to 110...
Checked what the limitations might be, in terms of technology, referring to the venerable book All About Telescopes. The limit of a 3" telescope is around magnitude 11. For a 6" telescope, mag 13.
I tried to have a bit of fun here. Doubles that are not just that. Triples and quads. Targets near interesting objects. Some stars where one might react, "I didn't know what was a double!" And so on. That'll be neat if I can nurture this.
SkyTools was so helpful in this! With detailed data. And the simulated views. Amazingly helpful.
