| Comments |
IC4592, 1.5deg East of the upper claw of Scorpious is quite faint. I used Maxim’s Lognormal Histogram Specification to see if any data was even being recorded. There’s practically no H-a component at all. A whole night's images had to be re-imaged because what appeared to be bat poop on the lens. |
