Though the sky is clear and the moon is 12 or so days old. It's
would probably be interesting to look at the moon as it's not quite
full yet, but washing out nearly everything else, but I'm notgoing to beause I want to run an experiment.
Tonight I'm going to try my new Nite Saver red goggles from Astro Engineering. They are supposed to serve 2 purposes:
1) If you are out viewing and need to run in to the house for
something, throq on the deep red goggles to avoid ruining your night
2) If you are going to have an observation session in a bit and
want to get a head start on building up night vision, wear them around
the house for 1/2 hour or so.
Here is an experiment with #2 to see if it works.
After some night driving, then spending an hour in the house with
normal lights on, I walked outside to see what I can see.
- Limiting naked eye magnitude: 4.3
- Moon: 15 degrees high
- Limiting naked eye magnitude: 5.1
- Moon: 15 degrees
After 1/2 hour of wearing them indoors and working on my computer, it
seemed to make a difference in about a magnitude of visible naked eye
stars. Cool. My kids think I'm a freak and the dog barks at me because
she doesn't recognize the stranger in the goggles, but so what!
