Hi,
here are my Venus images from the last 3 days captured during the late afternoon in variable seeing conditions using an Astrodon UV and a Thorlabs FELH1000 filter.
Thanks Trevor, the Japanese JAXA team are looking at the dark circular area , it's possibly an equatorially-trapped Kelvin wave but doesn't really fit their known data.
Just had an email from the Akatsuki mission team they are going to try using the LIR camera which uses thermal emission sensors and can track the dark spot over the night side if it is heat related. Interesting planet Venus with it's heat and sulphuric acid clouds which charge across the surface right to left.
Thank you all for your generous comments I'll keep at Venus as I need the practice. My goal is to capture the dark surface details next year when the bright crescent is much smaller. To this aim I have made an occulting bar which I hope will allow me to get more hot surface detail than otherwise possible.
Cheers, Phil
awesome Phil!
have you considered making a false colour or two with these? they are certainly good enough to...
I have thought about it but what colour is Venus? It's atmosphere is a complex mixture, although it is white to the human eye it would possibly be a pale yellowish grey. Any suggestions? an feel free to use mine for testing.

thanks Phil,
here is just a pure RGB combine done in photoshop. the
B UV
G UV/IR 50% blend
R IR
think it looks fairly natural? comes out white with a bit of brown?
Venus IR & UV taken during the last 10 days with conditions very variable. I’m expecting the Jetstream will moderate and drift southward allowing the possibility for better quality images in the coming months. I am now 90% retired so more time will be available for planetary capture and processing, if this old brain can stand the pace.
