Re: HD 189735

I'm thinking that HD 189797 and GSC 1071-1970 would be good if 
you can fit them in the field.

                  B     V     B-V
HD 189735       9.90  9.67   0.23
HD 189797       9.60  9.37   0.23
GSC 1071-1970  10.61 10.50   0.11
HD 189662       7.90  7.50   0.40

HD 189797 is about 11.5 arc minutes away and is a perfect match. 
GSC 1071-1970 is only 4 arcmin away. I'll be able to fit all of 
these in my field. HD 189662 is a bright one right near by that 
could work, too. Current TASS data has max=9.624 and min=10.036 
so I'd be tempted to use HD 189797 and GSC 1071-1970 to sandwich 
it.

They are calling it clear here tonight, so I should get some 
preliminary data.
