Here are a few Venus images.
It looks like there are some shadings in the 1-micron image,as seen in several occasions.
UV filter used is from Schuler.

Seeing 4/10 Trans 9/10 (varying)
Finally weather conditions have improved enough for me to take new Venus images.
As it seems that spring is finally at hand and the clouds have lifted from the Netherlands,
I hope to image Venus more often.
I try to sample at least four channels if I can, one violet channel at 390 nm, a blue violet
channel at 380-470 nm and two NIR channels at >780 nm and >1000 nm. I also try sto sample
some visual channels if I get the chance.
Conditions here in the Netherlands are better, with far les clouds, but the seeing is not
optimal yet. It's good enough to record some detail. Often de planets rim is distorted,
but details can still be discerned on the disc.
