Venus

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)

equipment used
40 cm Dobson made by Rik ter Horst
ZWO ASI174MM

Venus

Here is a comparison image of Venus on March 22 and 23.

In both cases I used UV as luminance (and UV = W47+BG39)

Then the RGB was mapped like this:
march 22: R-(g)-UV
march 23: IR-(g)-UV
where (g) is a synthethic green channel (just the average of the other two). On March 22 I didn't capture IR, so I just R for red ;) The IR and R recordings were very much comparable, as I didn't process them hard at all (so all the color information basically comes from the UV channel).

Here is a small animation in UV light (with a W47 filter) showing clouds moving rapidly on Venus. The animation spans only 35 minutes.



The still image shows Venus in UV-RGB.

Venus

The seeing seemed pretty decent, but the transparancy was very poor this evening. I only managed to take one quick run of images from uv, b, g, r to ir in a couple minutes time, before Venus disappeared behind the clouds completely. Attached is the rather soft looking RGB result.

North is up (usually I have south up, but I\'m too lazy to change it ;) )

Venus

Animation of two stacks of recordings in infrared light (>807nm) taken 45 minutes apart.

You can see some cloud structures moving on the planet.

Seeing was not very good (but hurray for long wavelengths!), next time I hope the clouds don't interfere with imaging, because it would be nice to get a longer/smoother animation.
