At the group site in Capitol Reef I/we easily saw the gegenschien at the anticipated position.
Thanks, that's wonderful. I was looking for confirmation that the gegenschein ephemeris works. Looks like my ephemeris spreadsheet works. Thanks, greatly.
I plan to go up to the Skyline Drive this week to try and photograph the gegenschein from there.
I don't know the sky there. Hopefully, it will be dark enough.
I tried to also capture the gegenschien but I was never sure that what I saw on the film wasn't the center-image brightening associated with fast camera lenses. I'm hoping that a digital image will help avoid this problem.
I understand from Covington's book that the confirmation trick is to take two pictures separated by time but centered on the same alt-az point. If the spot moves with the sky background - that's the gegenschein.
Should Gegenschein be capitalized for some reason? I've seen it both ways.
It's german spelling. In german, nouns typically are captialized. I am not sure of the proper english grammer rule - whether capitalization of words borrowed from other languages should be honored. In english, "the region of counterglow" would not be capitalized. I've also been misspelling it. It's "schein" not "schien". - Kurt _______________________________________________ Sent via CSolutions - http://www.csolutions.net
