Looking for a diagonal
Anyone know of something like this Stellarvue diagonal being available? Googling doesn't seem to find any equivalent.
" 1 1/4"90 Degree Fully Multi-coated, Focusing Erecting Prism The correct image erecting prism is fully multicoated for superior contrast. It comes with a 1.25" helical focuser with set screw and features 15mm of focus travel by turning the rubber grip. Made for standard for 1.25" eyepieces. #D1026AF "
This one is available from Stellarvue - USD59. Maybe also from OPT.
I'm looking for 90 deg, 1.25" diagonal, erecting prism with a helical focusser built in. Not too much to ask, surely?
