“Splitability” for double-star observers
Recently, one of my AstroPlanner users, Wilfried Knapp, posted this message:
On the CN DSO forum is a rule of thumb for splitting double stars in discussion: Multiply delta-m (if less than 1 then set 1) with the Dawes limit of your scope to get the minimum separation you need to split this double star under otherwise excellent conditions (seeing etc.).
This rule would be nice if available as wizard or better as option when searching double star catalogues.
This seemed like a perfectly useful and easy-to-implement way of rejecting double stars that will not be splittable through a particular telescope, even under perfect conditions. So I decided to integrate it into V2.1.
