Quote:When Comet ISON makes its perihelion dive on Thanksgiving Day, I would like to be able to observe it safely with a tracking sun-shield that keeps its edge close to the comet nucleus on the sun-ward side. To do this I need to be able to accurately predict the position of both the sun and the comet in my sky - down to the very fast perihelion pinturn (I expect the nuclear region becomes non-observable at closest approach). Being able to produce plots of the apparent comet movement in a sun-centered view as well as plots of both sun and comet in the sky would be useful.Any recommendations for the best software for this purpose?Such a tracking sun-mask system would be useful for daytime observing of Mercury and Venus also.
