I have had better luck taking them off. You can get ghost images of the brighter stars due to reflections from the lens hitting the inside of the filter, then going back through the lens. Other than the internal reflection issue, there is probably little difference.

Saturn's rings

Posted By Steve Mathis

You won't be seeing much of Saturn's rings for quite a while! They will continue to diminish as we approach the "ring plane crossing" on Sept. 4, 2009, at which point we will be viewing them edge-on. After that, they will slowly "open up" again, reaching their full glory in 2016.

M31 Attempt - advice needed

Posted By Steve Mathis

Hey, Phil...The "red" sky in you single JPEG looks like light pollution to me. It would be hard to get a very deep exposure under those conditions. On the stock lens that came with my D70, I have found good focus by manually setting the lens so the indicator on the barrel is centered on the infinity sign. If your lens allows this it would be worth a try.

Warm fingers

I'm wondering what it would take to adapt these to use a 12 V cigarette-lighter type plug. Is a USB port 5V? Would 12V overheat the gloves if they were in series?
