Re: [Utah-astronomy] Observing Report from the Gravel Pit
It would seem that late winter would be best for splitting Antares when it is rising in the the early morning and seeing is more stable. It is way too warm and balmy this time of year for tight doubles. Higher elevations are necessary for this one, such as Wolf Creek to get better seeing. Debbie
Not necessarily. Re-read my post, (as well as Don's, he's onto the "dusk" thing too). It's differential air temperatures that cause bad seeing, not "warm" or "balmy" conditions alone. In fact the best "seeing" (steady air) is typically in summertime, but the best "transparency" (no dust) is typically in winter. I've split Antares from SLC many times in the past, almost always in summer, but not since about 1979. YMMV --- UTAHDEB@aol.com wrote:

My comment that it was balmy was only about how comfortable the temperature seemed at the gravel pit that night before the moon rose, not anything more scientific like seeing or transparancy. By 2:30 a.m. the night got so cold that I had to turn my car's heater on so I could pack stuff. -- Joe

Sorry, Joe, I was replying to Debbie's post, not yours. She used the word "balmy" also, but pertaining to splitting close doubles. --- Joe Bauman <bau@desnews.com> wrote:
