The Galaxy M-81

© 2017 Klaus Brasch

I finally managed to collect enough individual exposures of one of my favorite galaxies, M-81 taken exclusively with my C-14 HD at f/7.5. This is a composite of about 12 x 5 minute frames at ISO 3200-6400 with my modified Canon 6D and IDAS LPS-V4 filter, stacked in Registar and processed in Photoshop CS-6.
