Venus 09.04.2012

Fused Silica Barlow; ~f/24,5; Channels: infrared deepest (silicon window), infrared deep (1000 nm longpass), UV (Astrodon UVenus); color - IR/IR/UV; 18:30 - 18:40:

f/10; Channels: infrared deepest (silicon window), infrared deep (1000 nm longpass), UV (Astrodon UVenus); color - IR/IR/UV; 18:15-18:20 UT:

Venus 11.02.2012

Venus in false colors: L1000-#47-UVenus:

Venus in UV - Astrodon UVenus, 16:42 and double 16:45:

Venus in UV - Violet Wratten #47 + Schott BG39 - 16:56:

Venus 06.01.2011

RG1000 at 4:46 UTC:

Silicon window at 4:55 UTC:

Night side check: RG1000 at 0,1 sec and 0,5 sec, Silicon window at 0,5 sec

Both filters failed (while RG1000 was successful in november). Too high phase, so the question if silicon filter can catch the night side is unanswered ;)

Venus 05.01.2011

Venus f/10, Ir-RGB 6:18 UTC. No much of detail in visual range:

Venus f/10, Ir-G-UV false colors and UV gives some details:

UV filtr is BG39+UG1 Schott glass

Venus f/10, infrared channel, RG850 filter, f/10, 6:18 UTC

Venus f/10, near infrared channel, silicon filter, 6:09 UTC

Silicon window is a polished piece of pure silicon (Si) that looks like a filter. It starts transmiting somewhere between 1000-1100 and by default it's not designed for CCDs that go blind at ~1100 nm ;) I was trying to catch Venus night side with it (as I did with RG1000) but today I didn't got any signs of the night side. I'll try tomorrow with RG1000 and Si side by side. The phase of day side may be to big.

Venus f/28, ProPlanet 742, 5:49 UTC:
