Re: ATM Baffling a newt - street light tests

Tom:

I use a focused high powered flashlight beam - have someone aim it all
over the scope from all sorts of orientations while you look through the
eyepiece with your eye severly cupped so that you can only see what's
through the eyepiece.  If you cannot tell when the flashlight is on or
off, then you are ok - that's my test for my super open no shroud light
dobs.  Moon glow at a slight angle can be handled well by a focuser
baffle and felt opposite the diagonal - works quite well for me.
