The Moon and Venus

Sometimes when you’re setting up to take pictures of incredibly dim things, the sky presents you with something incredibly bright and beautiful. The moon and Venus were in conjunction in this evening’s western sky. I used an H-alpha filter as a sort of 99% neutral gradient filter so they wouldn’t overwhelm the sensor.  This is a single 0.2 second exposure, through a 6 nm H-alpha filter, with the STL-11000M on the FSQ-106ED.

The Moon and Venus in Conjunction (9/8/13)

For perspective, tiny little Venus there is actually 3.5 times bigger than the moon, but 415 times further away. The light from the moon took about 1.3 seconds to get here; the light from Venus traveled for almost nine minutes.
