The all-surface, fully multi-coated system provides precise color definition for a brighter and sharper image. The body of the scope is waterproof to JIS Protection Class 7 and is filled with dry nitrogen to prevent internal fogging. The body, which weighs only 1.5 lbs., has a 1/4" - 20 threading for mounting to a tripod. The compatible eyepieces for the TSN-602 (sold separately) are the TE-9Z zoom eyepiece, the TE-14WD 30x Wide Angle eyepiece, or the TE-17HD 25x Long Eye Relief eyepiece.
