Hi Paul -
Nice work! The markings in your UV image are similar to ones I recorded a day earlier using a Baader CaK filter.

Clavius, 23rd SeptemberPosted By Alan Friedman |
Hi Anthony -
Superb resolution in this image! I travelled to NYC this weekend by train and had some (rare) uninterrupted time to work on processing a Clavius image from my new 41AF02 camera. It won't approach the level of detail in your shot...
cheers-
Alan

Congrats Alan Friedman, Nov Astronomy p86Posted By Alan Friedman |
Thanks for the notice. They chose to use an older image which I liked very much at the time it was made. There is, however, a spectacular image posted here recently that blows it out the door!

Hi Paul -
Nothing like starting off early in the apparition to make mars seem big at 10 arc seconds... nice work!

I've read that the Baader Calcium K-Line Solar Filter may be used to image Venusian cloud patterns but I never gave it any serious consideration, until now. Did you use an IR-cut with that and could you observe any of those magnificent clouds?
Thanks, Dan. I have the CaK-line filter for solar imaging with a Baader Herschel wedge. My guess is the U filter with it's wider bandpass and better coverage into the near UV would produce an image with more contrast. I did not use an IR cut filter - this is needed with the solar continuum filter but not (I think!) with the CaK. I did glance at the image in the eyepiece but could see a hint of cloud markings. Our eyes are not very sensitive at these wavelengths.
clear skies!
