In Ir-IR(G)W47

Venus in infrared and ultraviolet light. False color combination all have the same color scheme (red is the slightly processed Ir-channel, blue is the ultraviolet W47 + BG39 combination, and green is a mixture of blue and red. This is the data in the bottom center image).

The luminance channel bottom left is W47, bottom right is Ir (harsh processing).

I only had 15 minutes of imaging time before the next clouds were coming in. I managed to take this false colour RGB image of Venus. The seeing was very bad.

Red: Baader Infrared Pass
Blue: Wratten 47 + BG39
Green: (R + B) /2

My best image of Venus to date. It's a false colour image: ir pass (>680nm) is used as red, a wratten 47 filter combined with my baader uv/ir block fitler is used for the blue. Green is a mixture of R + B.

Venus in infrared (Astronomik ProPlanet 742 IR-pass filter). In total 2000 frames were shot using the Philips 840k b/w webcam. Conditions were far from great (as usual), there was a lot of wind (Venus was blown out of the field of view quite often), but nevertheless I managed to shoot a couple of avis.

Not even a tiny hint of cloud structure is visible in this result image. I really need an UV-pass filter for this (or maybe a W47 would do the trick as well). To make Venus look a bit more interesting, I added a little bit of yellow color to the final image.

A homemade filter was used to get this images of venus. The specifications of the filter are not known, but it probably behaved somewhat like an IR pass filter.

The image has been combined with an RGB image I shot the same evening to get some colour in the image.
