Telephotography (taking high magnification photographs) is now easier than ever to enjoy using Opticron telescopes in conjunction with SLR & D-SLR cameras. In this system the camera lens is substituted for the telescope and coupled directly to the SLR camera body using either a telephoto adapter or an eyepiece and photoadapter combination. T-mounts, available for nearly all makes of SLR cameras are needed to connect the assembly to the camera body. It should be noted that while it is possible to take perfectly acceptable high magnification photographs of wildlife in a wide range of environments using a telescope as a telephoto lens, the relatively small apertures, fields of view and depth of focus put an upper limit on the quality of the final image and one’s ability to successfully frame shots at close range.

The chart below shows the current range of telephotoadapters and photoadapters available to enable you to convert your Opticron telescope into a long focal length telephoto lens.

Notes. Focusing is facilitated on the telescope. Camera may need to be operated in 'MANUAL' mode with shutter locks disengaged where necessary. The high magnification to aperture ratios result in slower shutter speeds compared with conventional telephoto lenses so ISO400+ settings are suggested when using D-SLRs. If possible use a cable release or remote control to reduce camera shake when operating the shutter.

Equivalent focal lengths with HR, ES & GS telescopes fitted with either HDF T 40810 eyepiece or HR2 40933 eyepiece at lowest magnification setting and using a 35mm SLR camera*

For use with HR 66 (1000mm/f.15), HR 80 (1350mm/f.16.8), ES 80 (1150mm/f.14.4), ES 100 (1500mm/f.15), GS 52 (650mm/f.12.5), GS 665 (900mm/f.13.5), GS 815 (1150mm/f.14.1)

Fitting smaller diameter eyepieces

The 41111 Photoadapter Push Fit 44 can be used with smaller diameter eyepieces by replacing the inner sleeve supplied with on of the following reducer sleeves:

a. 41117 reducer 44~40 enabling connecting to HR2 40930, HR2 40931, IS 40916S and 40918S eyepieces

b. 41118 reducer 44~37 enabling connection to fold down rubber eyecup versions of HDF eyepieces 40810 and 40809

* These are approximate figures based on 35mm SLR cameras. D-SLR cameras use different size image sensors compared to 35mm and so an equivalent conversion figure must be calculated separately.
