Removed briefly from the original plastic bag to take pictures (lens caps were left on the entire time). New photos available that show the eyepiece more clearly than the plastic-wrapped shots. Still in the original Takahashi box, which looks brand new. Dealer label on the box reads $500.00, TKA00531, TAK LE-50MM, OCULAR 2IN (R-7.1). Barrel is marked MC LE 50mm. Because the lens caps stayed on, the optics were not inspected under a light. From the outside it appears unused.
The LE series is Takahashi’s long-eye-relief line, made in Japan, and is now discontinued. Five elements in three groups, fully multi-coated. Best matched to scopes around f/7 to f/10, and especially Takahashi Mewlon / Dall-Kirkham scopes with the CRS corrector, where the 40 mm and 50 mm were optimized for a flatter field.
Specs (Takahashi):
• Focal length: 50 mm
• Apparent field: 52°
• Eye relief: 40 mm (comfortable with glasses)
• Barrel: 2 inch (50.8 mm)
• Height: 151 mm
• Diameter: 63 mm
• Weight: 530 g
Low-power deep-sky eyepiece for long-focal-length scopes. On a 2000 mm focal length it gives 40x; on a 2500 mm scope, 50x. Threaded for 2-inch filters.
Ships in the original box, well packed.
