The new generation of this zoom eyepiece is now equipped with a modern screw-type eyecup.
Kowa's internal designation of the eyepiece is TE-9Z. The eyepiece fits all tubes in the current series TSN-82SV, 660 and 600. It also fits the old 1980s-90s series TS-610 (TS-611/TS-613) and the successor to the classic "gray sow", TS-601 and above all, the extremely popular TSN-1 and TSN-3 Prominar. In order for it to fit the TSN-820, a bayonet adapter is required (see next to this), but then the ability to quickly change between the eyepieces of the different generations also disappears. Comes with a plastic lens cover that can be anchored to the equipment.
Note! If you want to upgrade your old TSN-1 with this eyepiece, and have an original hard plastic eyepiece cover with threaded adapter, this must be removed.
