Re: Mysterious red streak in astro frame?

D800 has a shutter to close off viewfinder. Try closing it next time and see if that stops it.

The other problem I have read is VR can generate some infrared signal. Make sure its turned off or try a non VR lens.

I have a D800E and have never seen that phenomena.

By the way 200mm will be impossible without a mount tracking it of some type. Polarie would be maxed out with such a heavy lens but would probably cope. That is the minimum and even then 60 seconds is probably tops.
