EPISODE 109 - Collimation Participation!

Welcome baaaack to The Astrocast! Roo's been deep in the world of Schmidt-Cassegrains. This week he walks through exactly how he finally got his Celestron C8 collimated...mostly. Using a combination of SharpCap, a bright star, the "donut method", and a cardboard-and-painter's-tape mask.. plus one mystery that's still left to solve. He also covers his growing non-ZWO C8 build (Player One guiding, a Gemini EAF, SVBony power), how a 30ft active USB 3.0 cable let him run the backyard pier straight from his studio PC, a new TeleGizmos 365 cover, and why iOptron's truss-tube RCs belong on the "retirement scope" list. Plus an Astro Peak update and winter targets on deck...hello, Pleiades!
