I did see an image of Venus on FB that used a polarising filter and seemed to show some detail. Anyone know much about this method?
The Jupiter image shows a bit more detail than my other image from earlier in the evening. Io is just off the limb and the GRS is disappearing from view round the limb.

C & CC welcome as always.  |
Great result Pete. Your Venus is as sharp as one would expect.
I tried it last night right on the dot at sunset so the sky was still blue. From the feed it was very stable both in IR (807nm) and UV. I haven't stacked yet. I have a few polarizing filters but I never tried on Venus. Do you have a link to the pics?
Your Jup shot looks real good. Very nice details.
