Try a polarizing filter. Orion sells one for about $30. It is variable so you can dial the intensity of light the filter will allow- thus you can view the moon at any phase but still control the contrast. StG On Wednesday, March 31, 2004, at 08:36 AM, Griffin Louis A Civ OO-ALC/MAKGBA wrote:

Jim, after your post yesterday I got both of my scopes out and had a look, I am intrigued, but I definately need some filtration especially with the dob, but even the Mak Newt was painfully bright but the contrast at the edge of the darkness was phenomenal. What filter would work the best at just keeping the light down - any idea how dark it needs to be?

Lou Using high magnification/short focal length eyepieces help cut down brightness also. The short focal length eyepiece is looking at a smaller portion of the focal plane thereby rejecting much of the other light. The trade off is, then you have to track the object more vigorously.
