Venus in UV 12th February 2020

Further to my recent efforts to image Venus with a UV filter, I decided to splash out and get a ZWO ASI 290MM Mini. With its super-sensitive sensor and high frame-rate I thought it was better suited to the UV filter, and so it has proved to be. I think I was lucky to get hold of this camera. With China shutting down at the moment with THE BUG, supplies of ZWO cameras and similar items seem to have run out here in the UK.

As I lamented previously, my other cameras could only manage exposures of around 1/4 second (250ms) with this filter. Not sufficient to capture the seeing. However, this time I managed exposures of 15ms.

I'm now awaiting the delivery of an IR filter, so that I can prepare some false-colour images of the clouds. Looking forward to some calmer, clear weather.

Baader U-filter, 3x Televue Barlow, Omegon RC8 (effective focal length 4800) and a ZWO ASI 290MM Mini Mono camera. 7000 frames stacked in Registax.

Nicely captured Luke, good to see progress. Amazing how different the view was tonight, no sign of the "v" shaped cloud formation, your image is very similar to what i am about to post, which is very comforting to see.
