Description

A couple of firsts here: my first attempt at a deep sky object with a Star Adventurer mount, and my first look at Rho Ophuichi. I was a little disappointed that the reds were so dim, but I wasn't using the modified camera and there's only so much I can wring out of 19 frames. The heavy camera and lens were probably bit too much for the Star Adventurer to handle without a counterweight, and I lost a bunch of subs to stretched stars.
