The Burgess Optical/TMB MRF
power red-dot type finder adapted for mounting on
telescopes and binoculars of all types. Features
include four different reticules, seven levels of
brightness control, and a light weight and compact
TM
design. The MRF finder has a precision ground
reflex lens with minimal parallax. Included with
TM
the MRF finder is a base that allows the MRF
finder to be easily removed and stored.
TM
The MRF finder is used with both eyes open
and one eye directly behind the MRF
One of four red reticules is superimposed on the
sky, and the telescope is aimed by moving
the telescope until the red dot of the reticule
is superimposed on the target.

Use and Operation
TM
First, turn on the MRF
Power/Brightness Switch. The Off position is as pictured
with the 0 on the switch aligned with the white dot. The
switch has click stops at the seven Brightness settings
and the Off position. Turn the power/brightness control
until the desired brightness of the reticule is reached. A
setting of 1 is the dimmest setting suitable for night use.
Second, rotate the Reticule Selector until the desired
reticule is displayed. Lastly, it is a good practice to verify
TM
that the MRF finder is aligned with the telescope each
TM
time the MRF finder is attached to the telescope.
Keep both eyes open and position one eye at a
comfortable distance behind the MRF
behind the finder will see the reticule pattern
superimposed upon the view seen by the other eye. Eye
placement behind the MRF
because the finder has very little parallax, that is, the
reticule remains superimposed on the same part of the
sky as the eye moves behind the MRF
telescope is moved until the center dot overlays the
object to be viewed.
