Just when I thought I was able to accurately predict good seeing based upon wind speeds at different altitudes, the weather goes and changes the rules. Windy.com predicted less than 50 km/h winds at every altitude all the way up to space, so I was expecting good seeing. However, this wasn't the case, and the seeing was only fair (4/7) at best. 

 

I set up early to try and capture some clouds on Venus using my W47 Violet and UV/IR cut filters. Venus was jumping around all over the place and the low signal level meant FC was having trouble finding the planet to apply the cut-out box, but with a bit more gain I was able to get a result. Here it is at 200% captured size with a bit of added contrast, maybe you can see a cloud or two?

Next was Saturn, and I found it really hard to get a decent result. Here it is at captured size, nothing to write home about.

Finally I had a go at Neptune, which was quite difficult to find for some reason. I couldn't see it in the finder so I had to hunt around a bit. Eventually I found it, here's the result at 200% captured size with Triton.

Good efforts, Andrew, especially Venus. I haven't seen any worthwhile near-UV images on ALPO Japan for a long time - it's almost all IR - so you've done much better than most with this capture.
