I have a working Night Vision PVS-14 chassis that was modified for c-mount lenses and helical focuser for 1.25" telescope ocular (25 mm).
All functions of the chassis are working fine except for IR light.
I have recently sold the Gen 3 ANVIS MX-10160C tube so now the chassis is also for sale.
I am also including the Ricoh c-mount lens (24 mm f1.4) that is covering the whole 22 mm tube window (no vigneting).
25 mm ocular with helical focuser is also included.
