Inverse Afterthought

Fat Crescent Moon
The waxing crescent Moon, 35% illuminated.

I’d call this an afterthought, but it was the first thing I shot last night.  It is also the nicest shot I did all week…although the Moon is a decidedly easier target than the wispy deep sky objects I love so much.

Anyway, I was about to shoot M78 knowing I was going to fight the light pollution from this puppy the whole time, so I thought I might as well shoot it quickly before I started to fight it.

This is a stack of 9 images, shot at 1/500 of a second at ISO 200 on a 127 mm APO tube with focal length of 660 MM and f/5.2.

Super Moon Eclipse

Super Moon Eclipse
This was awesome to watch.

The Lunar eclipse on Sep 27, 2015 happened when the Moon was at perigee, the point in its orbit which is closest to Earth.  Not only does the moon appear just a bit bigger then, but, when it coincides with a Lunar eclipse the Moon can get deeper into Earths shadow, making for a particularly dark eclipse.

I shot this with a 952 mm focal length (f/7.5) APO refractor.  This is a combination of 40 shots, a mix of 2 seconds at ISO 400, 1 second at ISO 800 and 0.5 seconds at ISO 1600.
