I tried to catch Venus higher this time and it made a fair difference. I also used a 807nm IR bandpass instead of 742nm. The UV channel was a lot clearer this time as I was away from the roofs. As a result I got a bit more fine details. Cloud patterns look different in the UV channel from last week so I included a roll over. I guess that's expected.
Wow that’s good mate! I’ve got a couple filters on the way and definitely going to come back and have another go. May I ask about what time/elevation you found was best?
Awesome result Marc. The animation is grand and shows heaps
Thanks mate One week makes a difference. Few missing days in between. Not much changes within one hour though but I need to refine my capture settings and processing techniques to show more.

Thanks Dave . Catch it as high as you can. That's my advice. As it goes closer to the horizon you can really tell the captures degrade. I'll have to check but it was above 30 degrees when I started and the sky was still blue. Which creates another problem. Background noise. So the sweet spot is when the sky gets darker and the planet is still high. Last night would have been perfect if not for the clouds and seeing. This week end is clear but the jetstream forecast is really bad.
The animation clearly shows the change in structure from last week. Uber cool!
Thanks Pete I was reading Venus atmosphere is changing very rapidly. I can't see any changes or rotation within one session though Not like Jupiter or Mars. So I might stack all the sequences from now on see if I can increase the UV SNR.
Great! What filter you use for the “orange” tint on the first image?
Thanks Dale The bicolor is a blend 50/50 with IR mapped to red (807nm Astronomik) and UV mapped to blue (Baader U venus filter).

Thanks Bob. It's not a new thing. There are stacks of UV/IR shots of venus online if you google them. Some with a lot more details. I reckon to start doing planetary seriously you need an aperture in excess of 10"
Received the ZWO ADC. It's the cheapest of the ADCs. Most are in the $500 ball park. Top of the range goes up to 3000 euros. The ZWO has good reviews so will give it a go next clear night on Mercury and Venus. I also took the AR window off the camera and I intend to shoot in 16bit SER which is needed to tame noise and be able to record those elusive clouds.
Great work there Marc, most shots I've taken of Venus over the years have looked like a white blob! I didn't know it was possible to achieve surface details with amateur equipment. Thanks for enlightening me!
