RE: (IAAC) Obj: beti Cygnii (Albiero) - Inst: Orion 6" dobsonian
George:
I'm using a Celestron Microguide. See the article in the July S&T for
some techniques for using this for measuring doubles. And if you are
interested in doubles, you may want to take part in our projects: go
to 33-doubles@egroups.com for more information.
