Mike, remember, it is going to be mounted on the INSIDE of the attic in the hostel. I'll be drilling the hole through the siding, and mounting the camera on shelf brackets of some sort mounted on the wall, again on the inside.

I am curious about the glass... wouldn't that affect the clarity of the picture, especially with the 13-mile telephoto view? We're zooming to the 10x maximum.

However, I am concerned that blowing wind could bring dust to the camera, so maybe the glass is best. What do you think?
