We have a Green with IR blocking 50-mm diameter 2-mm thick filter (#17247part
of the LRGB set) with a long and very thin scratch on one side. It is so
thin that I don't believe it would ever show up in an image. Regular price

or 12.5% Transmission

We have replaced our old parfocal reducer with 0.62X reduction with our
new 0.7X model. The old model had a short back focus distance of only 29mm
but the correction is diffraction limited. These optics were designed for
fast APO's and give a well corrected field to 18mm. On a f/8 APO you would
end up with a f/5. Perfect for a ST2000 with color chip on a TAK or similar.
Only two left at $100.00 each.
Your choice of mounting plate at
no additional charge (a $55.00 value). Mounting plates are listed on the
bottom of page 3 of the price list.
