Venus in UV, 11th March 2020

[lukebl]

The seeing was pretty good this afternoon, and I managed to capture some good detail on Venus. High cloud meant that exposures were longer than I've previously achieved, and with fewer frames, but the good seeing more than compensated for that. Quite pleased with the result.

Captured with Baader U-Venus and IR filters, c. 7,000 frames for each channel. 24ms exposures @ c. 40fps. Green channel made from 50% UV and 50% IR . 3x Televue Barlow, Omegon RC8 (effective focal length 4800) and a ZWO ASI 290MM Mini Mono camera.

I'm always amazed by your images Luke. Thanks for posting!

Hope you don't mind Luke, but I flipped your image to compare the cloud detail with the sketch I made earlier this evening. I think there are enough similarities in position to convince me of the reality of the features in the visual appearance. Very bright visually of course!

Cracking shot, I'm very impressed with the detail you've captured @lukebl.

I have to agree @mikeDnight although there are some differences, there are enough similarities to convince me that you're seeing the same things.

That's an amazing sketch. You really must have excellent UV-sensitive eyes!
