could use a handy way to figure out what is what or who. and a way to predict there transit so they can be photo'ed and not be in the way of other photos.
There is no guarantee that a satellite will not pass through your FOV during your imaging, but there is one area that you absolutely stay away from.
The geostationary belt is a high density area of satellites that is the "no man's land" for long exposure imaging. The approximate declination of the GEO belt for southern Canada is about -6.5 degrees, but the higher in latitude you go, the lower declination the belt appears.
For the really bright satellites, you can go to Heavens Above (www.heavens-above.com), but it only predicts the naked eye satellites, which are few and far between. It is a good bet that very few of them would bother your images, unless you are using really high exposure times within a few hours after sunset or within a few hours before sunrise.

Good luck with the venture
Thank You.
