Which Kowa spotting scopes is this twist-up eyecup for?
This eyecup is designed for specific eyepieces used with the Kowa TSN-600, TSN-660M, and TSN-82SV series spotting scopes. It does not fit the scopes directly, but rather the eyepieces associated with them.
Will this Kowa eyecup fit my TE-11WZ II zoom eyepiece?
Kowa does not list the TE-11WZ II for this eyecup. It lists only the TE-9Z, TE-14WD, TE-21WH, TE-9WH and TE-14WH eyepiece models.
Is this an official Kowa part?
Yes. Kowa says all its spare parts are official Kowa products, so your optic remains in its original state. Kowa's material gives no fitting instructions for this eyecup.
Why should I replace a damaged eyecup on my TSN-82SV eyepiece?
A damaged or missing eyecup makes it harder to hold your eye at the correct distance, which can cause blackouts or a reduced field of view, and lets side light reach the eyepiece, which can reduce contrast. Replacing it restores the eyepiece's original part.
Which eyepiece models does this eyecup fit?
Kowa lists it for the TE-9Z, TE-14WD, TE-21WH, TE-9WH and TE-14WH eyepiece models, for TSN-600, TSN-660M and TSN-82SV series spotting scopes.
I lost my eyecup; does the Kowa Limited Lifetime Warranty cover this?
No. The Kowa Limited Lifetime Warranty covers defects in materials and workmanship. Lens caps and covers, cases, pouches and straps are covered for their lifetime but not for accidental loss, and a lost eyecup is not a defect, which is why Kowa offers this spare part.
