Kowa TE-17HD 25x Long Eye Relief Eyepiece for TSN-82SV

The Kowa TE-17HD is a fixed-power long eye relief eyepiece for the Kowa TSN-82SV and the TSN-600/660 series spotting scopes, and a long-time favorite for target shooting. Its 32 mm of eye relief lets you see the full field of view from your shooting position without pressing your eye to the ocular, so you can check mirage and spotter disks between shots and get back on the rifle quickly.
