The second generation of this classic eyepiece is equipped with a modern screw-type eyecup.
Kowa's internal designation of the eyepiece is TE-14WD. 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) as well as the successor to the classic "gray sow", TS-601 and above all, the extremely popular TSN-1 and TSN-3 Prominar. However, it no longer fits the predecessor of the TSN-82SV, which was called TSN-820 (821 and 823 Prominar most commonly in Sweden). 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! For Kowa TSN-1/3 with plastic eyepiece cover + threaded adapter, the adapter ring must be removed before mounting, otherwise the eyepiece, which has a larger outer diameter than the old TSN eyepieces, will not fit.
