15 Aquilae
15 Aql – h Aql – Double star in Aquila
This was the first time I’d measured separation of double stars. I used no special equipment and done a naive calculation just for fun. I may describe the method later, now the results:
PA: ~150°, separation: 42”
Not bad for the first try, Wikipedia mentions 39” separation.
