Telephotography

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 MM2 models to a

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 IS0 400+ settings are suggested when using D-SLRs.
For 35mm film SLRs 400/800ASA film is recommended. If possible use a cable
release or remote control to reduce camera ‘shake’ when operating the shutter.

Telephotography using digital compact cameras and camcorders

In this system the camera is positioned up against the eyepiece of the
telescope using the 40849 Universal Digital Camera Adapter. To get the
best results:

1. Use any of the following eyepieces: 40812M, 40810M or zoom

2. Use a camera/camcorder with a lens diameter as small as possible.

A T mount is required to connect the assembly to the camera

This is an approximate figure based on 35mm SLR cameras. Many D-SLRs use
different sized image sensors compared to 35mm so an equivalent telephoto
conversion figure must be calculated separately.

Getting Started

Your MM2 Mighty Midget telescope will open up a whole range of
new and exciting impressions, whether for general use or
specialist study.

Firstly extend the draw tube. To get the sharpest picture turn the
focus wheel slowly until the image being viewed becomes sharp.
To minimise image shake caused by high magnification the
instrument should be supported using a suitable tripod or mount
connected via the tripod socket located on the underside of the
main body.

If the eyepiece being used has a fold down or retractable rubber
eyecup it should be used in the down position when wearing
glasses. This ensures the maximum available field of view is
obtained. Be sure to return the eyecup to the up position if you or
anybody else wants to view without glasses. The retractable lens
hood should be extended when viewing in bright sunlight.

Care & Cleaning

To clean outer glass surfaces of any eyepiece and the objective lens, gently remove excess dirt and dust using a compressed air
device or a blower brush. Caution. Hard and persistent rubbing of dirty surfaces can cause abrasive scratches on the surface of
the glass which may distort viewing.Breathe on exposed glass surface and then wipe with an optical cleaning cloth (code

30277) in a circular motion until the surface is clean again. Do not attempt to dismantle the instrument as this will invalidate
the guarantee. WARNING. Never under any circumstances use a telescope to view the sun. Doing so will cause serious
damage to your eyes. Whenever possible store in a stable dry atmosphere away from moisture. For extra protection, use the gift
box or one of the optional cases available.
