Hi Al,
No, not a typo error, it is a K12mm EP originally supplied with the PST and it is fairly average in performance. Around 10mm - 12mm seems to be about the limit for clarity but I've found 15mm - 18mm to be the better. I have tried lots of EP's in the PST and they all work quite well, particularly Orthoscopics. I have a Solarmax40 with the BF15 blocking filter which is why I am selling the PST. In fact, visually, the PST is a little sharper than the Solarmax40 although I believe the Solarmax is better for imaging owing to the larger blocking filter. At around three times the price of a PST it should be.
