Date:  Feb 9, 2013

Location: Nevada City at 2512 feet

NELM: 6.0 – 6.2  (zenith)

Transparency: 3/5

Seeing: 2/5

 

Telescope: 22” f/4.0 reflector sitting on an equatorial platform

Eyepieces:  24mm Panoptic (finder eyepiece), 10 and 6mm ZAO-II’s, 10 and 6mm Delos and TMB 1.8x ED barlow

 

About 10 of us met at a site near Nevada City (2512 feet).  The skies are not too bad especially that sites near home during the winder are slim pickings.  I live right on the western slope of the Sierras, so once I head due east...in just 40 minutes I'm already in the snow and the sky glow is still pretty bad.  So this site is NE by 1:15 distance from home.  A neighbor about 200 yards away turned the lights on about 2 hours into the night, pretty much ruined the rest of the night.  Observed 4 new trios and some old favorites.

 

Note:  These notes are very raw as I was socializing most of the night while observing.  I will enhance them when I get the chance.



All object parameters in parenthesis are listed in RA and Dec without commas.
