Hi Dana,
If you want to use doubles for testing seeing, I'd prefer bright ones that are easy to find and ones where each component is relatively bright. Trying to split a mag 5 component A and a mag 10 component B at 1 arcsec separation would be a tough ask.
You may also want say stars less than +30 dec. However, that's up to you.
You can use the WDS Catalog.
Go to
http://heasarc.gsfc.nasa.gov/db-perl...n=More+Options
Under View, tick only and add where applicable (you can pick different values) ...
name
ra
dec <+30
spect type
separation date1 >1
separation date2 <5
comp1 mag <6
comp2 mag <7
then Start Search
Under ra select the down arrow to sort by ascending right ascension.
I used both the separation date1 and date2 fields as you can't do ">1 and <5" in the separation date2 field. It is possible separation date2 can end up less than 1. Just ignore these.
To get the names of the stars, select S under Services which takes you to the SIMBAD database.
Regards, Rob
