Here are more lunars with SNO-T. Oct 26, 0:0:0 GMT AP N 40d27.2', W 86d55.8' SNO-T, inverting scope, IC=0, T=61F, Pres: 30.04, height 12 ft, weather perfect. Frank's calculator. GMT 0:16:22 0:20:11 0:27:48 0:33:08 0:34:58 DIST 70d37.4' 70d38.9' 70d41.8' 70d43.2' 70d43.8' ERDIST -0.2' 0.0' 0.3' -0.1' -0.1' ERLONG -6.6' -0.1' 8.4' 3.1' 3.3' AVERAGE GMT: 0:26:28 AVERAGE DIST: 70d41.0' ERDIST: -0.1 ERLONG: -2.1 Comments. Longer time intervals indicate that I was more careful in my measurements than last time. Also I followed the advise to hold the sextant in the most convenient position: After catching the bodies close enough (without the scope, sextant upside down), I installed the scope and inverted my sextant so that the Moon was visible through the horizon glass. I had to use my intermediate filter (grey) to decrease the moon glare. The moon was very sharp with this filter. Without the filter, the star just disappeares when I bring it close enough to the moon. Alex.
