Brian, et al;
I think what I need is a little more scientific approach to this discussion
of seeing. I have only used a small sampling of stars for seeing tests:
Double-double in Lyra, Gamma Leo and one or two others that I can't remember
right now.
I know that a list was posted some time ago, and I think Brian was nice
enough to do that work, it included a list of a dozen or so double stars
that pass overhead and have a variety of separations.
Seeing as how my new Nexstar 11 will find stuff quickly and accurately, it
would be pretty easy to view these doubles at a consistent power (300?) and
keep notes on how well divided they are.
So, my question is: does someone still have that list in electronic form?
I need as a minimum, star designation, RA and Dec, magnitudes and
separation. Maybe some info on whether or not the stars are moving rapidly
in their orbits.
Thanks;
Steve Coe
