Opticron Telephotoadapter
For use with HR, ES, GS, MM3 & IS Fieldscopes.

This device is used to attach a DSLR Camera body to any of the above mentioned Opticron fieldscopes. In addition to this part you will also need a T-Mount (T-Ring) specific to the camera you are trying to use.
 
Your camera may need to be operated in manual mode with shutter locks disengaged where necessary, and focusing will need to be done using the telescope's focuser. The high magnification to aperture ratios of this method result in slower shutter speeds compared with conventional telephoto lenses, so choose an ISO setting of 400 or higher. If possible also use a cable release or remote control to reduce camera shake when operating the shutter. 

Here are the equivalent focal lengths when used with the following fieldscopes (1)
HR 66 - 800mm / f.12
HR 80 - 900mm / f.11.3
ES 80 - 950mm / f.11.9
ES 100 - 1250mm / f.12.5 
GS 52 - 530mm / f.10
GS 665 - 750mm / f.11.3
MM3 - 530mm / f.10.6 
IS 60 WP - 700mm / f.11.7 (2)
IS 70 R - 750mm / f.10.7 (2) 

(1) 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.

(2) Optional 40927S close focus adapter needed. Price inc. VAT £10.00
