No seasonal preferences that I could find, but that doesn't mean that they don't exist. I think the way to approach this is to decide when the particular Trojan point you are stalking will have as bland a background as possible. You'll also have to do some research with a planetarium program, and trace the moon's orbit sixty degrees ahead. The phase of the moon is important, since it must be below the horizon while the Trojan point is still fairly high. Waxing crescent to gibbous will set with the Trojan point still high. You could also plot the following Trojan point and wait for it to rise ahead of the moon, this time a waning gibbous to crescent phase would be best. A new moon would mean that the Trojan points are about sixty-degrees away from the sun, as well. How high would they be by the end or beginning of twilight? The thing to remember is that you are looking only 60-degrees ahead of, or following the moon- within a few degrees, remember that observers noted a bit of "wander". --- Rob Ratkowski Photography <ratkwski@hawaii.rr.com> wrote:
Hi Chuck
Thanks for the new challenge, I've done the ZL and Gegenschein, so this faint patch will be a good one to do from the top. Any mention if there was a better season or is a good dark, dry clear night a good stage to work from?? It looks as if tomorrow night would be good but I've been up at the summit now 5 times in 8 days and my honey is wondering what I'm up too .......
