Does anybody have one?
I've been looking around for a couple of weeks, including all the usual suspects: Orion, Meade, Celestron, Hoya, VernonScope and others. I cannot find one.
According to a chart on Page 83 of the August issue of Astronomy, this filter has a 17 percent transmission and works well in large telescopes.
