Venus
Monday, April 06th 2015 - 17:05 (UTC) - focal ratio f/30
Venus in IR (Astronomik ProPlanet 807) and UV (W47 + BG39) light.
IR mapped as red, UV as blue, and green is a 50/50 combination of the two.
I used the 5x powermate (and a dispersion corrector) for a change, which pushed the focal length a bit further than usual (I usually image with a 3x and a filterwheel + ADC and then the camera)
