Opticron Push-Fit 44 Photoadapter Black eyepiece accessory

Photoadapter Push Fit 44 <b>For use with selected HDF T, HDF, HR2 & IS eyepieces</b>

Equivalent focal lengths with HR, ES, GS, MM3 & IS scopes fitted with either HDF T 40810 eyepiece or HR2 40933 eyepiece set at lowest magnification and using a 35mm SLR camera (These are approximate figures based on 35mm SLR cameras. D-SLR/compact system cameras use different size image sensors compared to 35mm and so an equivalent telephoto conversion figure must be calculated separately).

HR 80 - 1350mm / f.16.8
ES 80 - 1150mm / f.14.4
ES 100 - 1500mm / f.15
