20080813 Moon

Seeing at something like 2-3/10, very poor, I can never make sure the correctness of the focus as well as the collimation which I tried to tweak tonight with the DBK on Jupiter and its satellites. Transparency like 7/10.

C5 at f/20 (Tele Vue 2x), DMK 31AF03.

2246 (GMT+8):-

2251 (GMT+8):-

Very poor seeing, cannot really do collimation well, and the combination of these two factors result in some sort of "double" image.
