Telephotography using SLR cameras (digital or film). In this system

the camera lens is substituted for the telescope + telephotoadapter or

telescope + eyepiece + photoadapter. To convert your ES fieldscope

into a telephoto lens (ES 80 950mm

/f.11.9, ES 100 1250mm

/f.12.5),

you will need a 40215 telephotoadapter. Alternatively connect a

suitable push fit photoadapter to your viewing eyepiece.

A T-mount

is required to connect the assembly to the camera body.

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 choose an IS0 setting of 400. For 35mm SLRs 400 ASA film is recommended. If

possible use a cable release or remote control to reduce camera shake when operating

the shutter.

This is an approximate figure based on 35mm SLR cameras. D-SLR cameras use

different sized image sensors compared to 35mm so an equivalent telephoto conversion figure must be calculated separately.

Digi-scoping with digital compact cameras and camcorders

Shooting high magnification photos and video through your telescope is possible if you have a suitable

camera or camcorder. To find out how suitable or not your camera is for digi-scoping, position it up to the

viewing eyepiece and see if an image appears on the screen. You may have to position the camera a few mm

away from the eyelens of the eyepiece and increase the zoom to get a full frame image.

The most suitable cameras are those with a lens diameter of 20mm or under and zoom range no greater than

5x. To get the best results you will also need to fit a low magnification wide angle eyepiece to your telescope or use a zoom

eyepiece set at minimum. To find out more about bespoke digi-scoping kits and universal mounts and brackets visit the
