Venus is about 16% illuminated and I thought I'd have another go at imaging the night side of the planet with a full spectrum Canon EOS 600D, 1.4x teleconverter, Baader 1.25" 685nm IR pass filter (placed on the end of the teleconverter), 12" Dobsonian. North is down.
Taken over two nights there is a definite feature appearing on the night side of the planet. I cannot see how it could be a processing artefact, and I was seeing it on the live view of the video.
The planet rotates so slowly (assuming it's either a surface feature or lower atmosphere cloud feature) that it is hard to confirm.
Thanks for looking,
Tom

Reason: North is down
This is very interesting, I bought a 1000nm filter for this but never got round to it. Your 685nm lets in too much light and stretching can create artifacts but you say you could see this in preview. You need several days/weeks so I will be watching. Love this interesting imaging Tom.

Tom I hope this link works if not you should call Steve at myastroshop as he images at this wavelength and has a lot of past data. I can see a similar feature in his pic.
PS if you come down for Xmas or New Year give me a call.

Bird has been imaging actual surface features on Venus lately and as a proof has animated a couple of data sets. Have attached a link. It is currently on facebook. It is the first example I have ever seen of surface detail on Venus captured by an amateur.
I'm having another shot tonight.
