If you need a power boost....I need a power reduction, so let's trade!
I have a 4mm Tele Vue Radian. No box or pupil guide, but the caps are there and the optics are excellent. Great high power views....just too high for my present scope! I'm looking for a late-model University Optics 40mm MK70 in good condition for low power use. Would be willing to do an even trade (to offset my missing box and pupil guide).
