Sometimes, simple objects can reward you with amazement and pleasure. Take double stars for instance. Most may be boring to observe telescopically but I'm sure most of you out there have come across one or more telescopic doubles that became a favorite of yours.
So the questions are what's your favorite(s) telescopic double and why (color? star field its in? seperation? etc.)?
My favorite is Alberio in Cygnus due to its colors of blue and yellow. Mr Q
