2-star clusters from my backyard on 7/5/04

by Peter McKone

It's been more than two weeks since the end of SSP, and photon deprivation was setting in. I set up the Intes Mak in my backyard to look at double stars. To avoid wasting my time, I started with Epsilon Lyra. No problem. Next was Mu Draco (Struve 2130). Nice evenly matched pair with separation = 2.2 arc seconds. Very clean at 240x. Would it be silly try 20 Draco (Struve 2118) with separation = 1.1"? Nice clean split at 350x! Seeing must be pretty good. Tried Zeta Bootes (Struve 1865) with separation = 0.7". No split. But nearby Pi Bootes (Struve 1864) was a nice consolation. Tried Nu Scorpio, but the seeing was not good there. Also failed to see a split in Struve 1834 (mag 8, sep 1.5") in the forearm of Arcturus, near Alkaid. Not sure why. Finished up with Epsilon Bootes (Struve 1877, Izar). Very pretty.
