ρ Aql area


Recommended Posts

I'm just putting together a map for this area, including Delphinus. I can't help noticing there's about 40 easy doubles within 2° of ρ Aql, mostly from the Chevalier catalogue. Odd to find such a high concentration in a small area.

There's a couple in there from Struve including a tight one. I wonder why he didn't pick up all these others?

Hi Michael

From experience some of the later double star observers were slightly over optimistic on the magnitudes of the pairs. 

I had an email conversation with Brian Mason about how much fainter Jonckheere doubles are compared to their listed magnitudes in the WDS..

This may have something to do with it.

Cheers

Ian
