The seeing was poor just before sunset last evening,but just good enough to produce these RGB and IR 642nm BP images.
Again,using evaporative cooling around the rear cell of the OTA for 3 hours prior to imaging helped a great deal.
The Oval BA is in transit on the p side of the CM.

The dismal weather has not relented. The best opportunity this week brought below average seeing
with a high cirrus cloud deck that caused the fps rate to dip below 60.
Likely BA setting on the limb and STB Tail visible in image.
