Venus with Baader UV filter, showing rotation over 2 days

[Pete Presland]

Venus is now at a very respectable altitude, plus some lovely clear skies. Perfect conditions (hopefully) to begin imaging it again.

Both images with Celestron C9.25, Asi290mm, Televue x1.8 Barlow and Baader UV filter. 25,000 frames captured, stacked 10%. Last image is with a Astronomik 807 filter.

Some nice detail visible on both days, particularly Saturday afternoon. It looks clearly like rotation visible to me over the 2 days?

Nice shots

Great work pete.

Those look excellent.  I'm not sure the 807 filter is very giving, but the detail from the Baader UV is amazing.

The only reason used it was because my 742 was in my filter wheel, just a bit lazy 🙂

The 807 is normally saved for really poor conditions

Terrific capture, can certainly see rotation.  Well done.

Very nice! Gret detail with the Baader UV. Definitely see the rotation.

It definitely moves but at 243 days one rotation maybe it is just the clouds what do. Excellent picture, I'm rather envious 🙂.

Nice captures. I have one of those Venus UV filters which I'm looking forward to trying out over the next few months.

BTW, although Venus rotates once every 243 days, the clouds circle the planet every 4 days so you can see changes over a relatively short period.

[Pete Presland]

I knew the clouds rotated quickly,  I thought it was around 9 days. 4 days though would explain the big difference in the 2 images.

What a nice surprise,  they asked me a while back if they could use it. I didn't think they would though, out on Thursday I think?

Brilliant, Pete; I can definitely see some rotation in your images. Enjoy those beautiful nights!

Cheers!
