Tracking Andromeda


That’s M31 – the Andromeda Galaxy – front and center. Mirach and Alpheratz are toward the bottom.  This is a combination of five images shot at 10 seconds f/4 ISO 1600 using the Canon t3i with 50mm f/2.8 lens. The five images were combined with DeepSkyStacker then brightened with the Windows Photo tool.  The sky was visually dark although it shows blue-grey above.


The Camera was mounted on my new-to-me ioptron Skytracker. I didn’t have a lot of luck aligning the tracker with Polaris, my vision is pretty poor at night, but I’ll keep trying.
