20070721 DBK Jupiter

Again, seeing is 3-4/10, transparency is 7-8/10, first shot is 1/8s and ~500 gain, second one is 1/15s and ~700 gain, a test between frame rate and exposure, third shot is re-focused, I didn't use NGF-S tonight.

2244 (GMT+8), f/30:-


2246 (GMT+8), f/30, my best C5 Jupiter ever, beat even all my previous C8 shots hands down, maybe due to the fact that I'm doing imaging indoor, more aperture does not really help, but optimizing smaller aperture is even more fruitful:-


2249 (GMT+8), f/30:-
