Thanks David. Focus is always hit and miss with the U filter, but with this evening's seeing I was actually able to see a bit of the banding in the live feed, so focus was possible.

Glad you like it Ray, actually I'm pretty pleased with this one too. Definitely my best result with the IR & UV filters so far!
I use a mono camera, and shoot three videos through photometric I, V, and U filters. Stack and sharpen each video, then combine them as RGB channels into a colour image, using I for R, V for G, and U for B. I use Gimp software, loading the three grayscale images as layers then using the Colors->Colorify function on each layer.
I have also seen others get good results shooting R, G, B, and U, and then making an LRGB image but using the U for L. I am going to give that a try next time.
There are a few special purpose "UVenus" filters on the market, which I think are a bit brighter than the Bessel U, but with a C11 and DMK21AU04 camera I still get 30 fps for U, even at f/25, so it's OK (but less than 50% histogram).
Superb!
Can't remember ever seeing so much detail in the cloud banding on Venus
Thanks Deeno. This was the best seeing I have had during the daytime for a long while.

very impressive ! !
Thanks Bob. Of course it is synthetic colour, but I like to think it's how the Venusian's see their own planet from space!

Cheers Derek, I agree. I love a good Saturn as much as anyone, but it's a shame Venus and Mercury don't get much of the spotlight. I suppose it's because the timing is a bit tricky, and it does require a bit more specialised gear.
