The instrument is very lightweight at only 5Kg
(11 lbs), and with the dewshield closed and eyepiece adapters removed, incredibly compact
at only 25 ins length. Note that both 2" and 1.25" eyepiece adapters are included as standard, including a 2"

G The MEF3 (and MEF4 - see price list for details) micro-focusers can be retro-fitted to any Takahashi refractor. The components include a stabilising bar plus all fixing screws. The 10:1 reduction in the gear not only means much finer control of focus, but perhaps equally important, the torque required to turn the knob is also reduced by ten times, so that at high power planets will remain steady in the field of view for easy precise focusing.

J The FQR1 quick-release finder unit can fit on to any of the Takahashi refractors, and can take brackets for the 5 x 25, 6 x 30 or 7 x 50 finders. The thumbscrew enables fast removal or attachment
of the bevel block.

L View showing the bevel block after removal from the base. The pin at centre back is a stop to ensure the correct position of the bevel block when inserted in the base
M With the finder and finder bracket detached the main instrument has no items projecting awkwardly
which greatly simplifies storage and carriage. In fact the FQR1 block does not protrude further than the focus knobs
