Sander, If I understand your question, you want to select an object and have CDC track that object as it refreshes the star positions as time passes. Without a telescope hooked up, I don't know how to do that. But if you have a goto telescope connected to CDC it's really easy. Under the Telescope menu there should be a Track Scope Position. When you select that, CDC will periodically ask the scope where it's pointing and (roughly) center that location on your screen. The frequency that it updates the scope position is controlled by the panel you use to attach to the scope. It doesn't need to be very often and certainly no more often than the rate that CDC refreshes itself. I generally use 2-5 seconds. This isn't really tracking the object you are aiming at -- it's really just tracking the scope. But I think it will do most of what you want. BTW there's also a toobar "Track" button that accomplishes the exact same thing. Note, the Track toolbar button has a small bug with a big explanation: Normally when you turn on the Tracking, the button becomes red to indicate that tracking is on. If you turn off tracking the button returns to its normal (usually black) color. However, there are times when CDC will turn off scope tracking by itself. The most common is when you tell it to look at another part of the sky. If it cannot track the scope position and show you the new location at the same time it will ask you if you want tracking to turn off. If you say yes, it cheerfully turns off scope tracking and shows you the part of the sky you asked for. However, it forgets to turn off the red font on the Track toolbar button. So if you see a red Track button you cannot assume that tracking is on.

The problem is that in this case the sky moves 'underneath' the projected area and the selected object is no longer centered. How do I prevent this from happening? I could turn off 'refresh' but that's not recommended when connected to a scope so I'm hoping there's a way to make this happen. In a related question, how do I keep the little arrow present in the screen when I zoom in or out? I mean the arrow that points at the selected object. Thanks, Sander [Non-text portions of this message have been removed] SPONSORED LINKS Chart <http://groups.yahoo.com/gads?t=ms&k=Chart+software&w1=Chart+software&w2=Org anization+chart+software&w3=Science+kits&w4=Science+education&w5=Astronomy+g ift&w6=Astronomy+magazine&c=6&s=138&.sig=EYHBELRVHEDaJd8OsJWEgg> software Organization <http://groups.yahoo.com/gads?t=ms&k=Organization+chart+software&w1=Chart+so ftware&w2=Organization+chart+software&w3=Science+kits&w4=Science+education&w 5=Astronomy+gift&w6=Astronomy+magazine&c=6&s=138&.sig=po4stjM5vWNw-cd-JbTt1w > chart software Science <http://groups.yahoo.com/gads?t=ms&k=Science+kits&w1=Chart+software&w2=Organ ization+chart+software&w3=Science+kits&w4=Science+education&w5=Astronomy+gif t&w6=Astronomy+magazine&c=6&s=138&.sig=_wohJrTp60vkmv6JwQgGgQ> kits Science <http://groups.yahoo.com/gads?t=ms&k=Science+education&w1=Chart+software&w2= Organization+chart+software&w3=Science+kits&w4=Science+education&w5=Astronom y+gift&w6=Astronomy+magazine&c=6&s=138&.sig=9-i8KEDrCXMVJVbTwSvDLg> education Astronomy <http://groups.yahoo.com/gads?t=ms&k=Astronomy+gift&w1=Chart+software&w2=Org anization+chart+software&w3=Science+kits&w4=Science+education&w5=Astronomy+g ift&w6=Astronomy+magazine&c=6&s=138&.sig=vCLWg1vz65tBgfFaKjKufg> gift Astronomy <http://groups.yahoo.com/gads?t=ms&k=Astronomy+magazine&w1=Chart+software&w2 =Organization+chart+software&w3=Science+kits&w4=Science+education&w5=Astrono my+gift&w6=Astronomy+magazine&c=6&s=138&.sig=u-CXCz-qvKpjGLT1ybn7QA> magazine _____ YAHOO!
