We have a Coolpix P500. We bought it first because it's a Nikon and second because of the zoom - 36x.
My first Nikon was an EM. What I liked about the EM was the interchangeable lens, and the cable release for the shutter. I'd install a 80 - 300mm zoom, put the camera on the tripod, connect the cable release, and take night pictures of the sky. I got fairly good at it, if I do say so myself.
So, here's my question. (Yes, finally.) Is there any way to connect a P500 to a telescope? Nothing fancy. Something from Celestron I imagine.
