Venus Clouds Patterns April 19th 2023

It's been a very long time since I did anything astronomy-related, but this afternoon I thought I'd get back into things and have a go at imaging Venus. And I'm glad I did. Despite Venus's relatively small size (15.7 arcsecs, 70% phase), and very blustery winds, I managed to capture some very clear cloud formations with the Baader U-Filter. I see these filters are now over £200, so I ought to make use of it. The really bright patch on the limb at 4 the O'clock position was very prominent.

Captured with a 250mm f/4.8 Newtonian, 5x Powermate, ZWO ASI290MM Mini cam, Baader U-Filter and Baader IR-Pass Filter.

About 3000 frames captured with the U-Filter, and about 10,000 with the IR Filter. Processed in Autostakkert, Registax and Photoshop. RGB thus: R(IR), G(50%U/IR), B(U)
