Sky conditions supposed to be excellent tonight,
too bad it is almost a full moon and the sky is totally washed out
for deepsky viewing. It is however an excellent opportunity
for me to systematically compare the impact of different colour
filters on the visible contrast of the Moon. I used my Lumicon
filter selector to rattle through my selection of filters.
Blue #80a and a single line polarizer (half of my variable
polarizer) provided the best improvement in image contrast.

Seeing and transparency were supposed to be
basically nil, but after kids in bed I noticed that I could clearly
see the moon, albeit through a thin layer of high altitude cloud.
I figured I'd go out anyway. You can tell the images are taken
through thin cloud as they're somewhat washed-out.

Another very cold night (-20degC). Mount
worked well, but laptop struggling. Never did get very steady
seeing, but then again the forecast didn't call for it.
