Last night I was using Cartes du Ciel (V3) to figure out the time that Jupiter would be moonless. However, increasing the time increments and watching Jupiter and its moons rotate, it never became moonless. One moon remained visible and the other moons started to become visible before that one moon had a chance to disappear. I ran the same cycle on CALSky and Jupiter did become moonless. I am using the same location information in CALSky as I do in Carte du Ciel. Is there an error in the program and can it be corrected? I have also noticed that the GRS transit times appear to be off as well as compared to CALSky. Any comments or suggestions would be greatly appreciated.
Thanks! Travis
