Brand new, immaculate, very high quality, came with my new 180mm maksutov. 1.25" standard of course. The barlow has an internal "no-mar" compression ring, the 13.7mm ocular has a very wide highly corrected image of 70 deg.
Strangely, Intes-Micro doesn't mark them for inclusion with scopes, but are identical to the photos.
APM/Markus Ludes sells the barlow for 89$ and the 13.7mm wide angle ocular for $99, take the 188$ set for $138 shipped in CONUS, 50 bucks off. Paypal encouraged.
