Astro Session, March 10

March 11, 2026

Astro setup tonight. We still have some snow, even with the warmest day we've had in a while, high of 74F/23C. I don't know if the weather's going to hold, but I might start on M51, Whirlpool Galaxy with the Apertura CarbonStar 150 (150mm diameter primary mirror, 600mm focal length at f/4) and the ZWO ASI715MC, which isn't the best camera for this, but we'll see how it does. I also have the ZWO ASI220MM off-axis and the 2inch Antlia UV/IR cut filter in the drawer.
