Does anyone know what the current separation is for this pair? I have read 1.7", but I think this is from 2003 or so. I had a nice clean split with my 120 / 900 at about 250x, so I'm curious.

1.70" is correct as of 2012 in the WDS, with a PA of 78 degrees.

I find 1.7" listed in most of my literature. A search on on AstroPlanner and all of the catalogs I have on it vary from 1.5 to 1.7" but I believe 1.7" to be more accurate...

looks like an easy one to starhop too also. I need to work on my winter doubles, but puppis and monoceros clusters keep pulling me away!

Know what you mean! I need to work on mine too when we get a good clear night! I went out a little earlier and most of the low clouds have moved on some but still have a few higher ones and the wind has kicked up a little... :mad:
