Description

Result of last night's 3.25 hours integration, using Nikon 300mm f/2.8 lens, ASI6200MM camera, and Baader 7nm Ha filter. I'm in awe of this new camera ... >70% QE at Ha wavelength. Combined with the fast lens and 3 hours yields incredible details.

Tonight oxygen light takes center stage.
