Re: ATM Baffling a newt - street light tests

I can attest to how well this works in Mel's scope first hand. 

I was _extremely_ skeptical of his open design initially, as I have always
been a strong supporter of shrouds and still are for various other reasons.
But he proved to me (with the test described below) at last year's Oregon
Star Party that his telescope's baffles completely blocked stray light from
all possible angles.
