Finally seeing gets better as Venus climbs higher up into the evening sky. UV
detail was easily visible in every single image tonight,but I am still not
satisfied with the overall sharpness in UV,which suffers at 0,7 sec. exposure
per image from the at best mediocre seeing. Combined false color RGB and
IR/UV-RGB this time for comparison.

Under very average conditions unfortunately -
IR image was taken at 122 frames/seconds:
