A.  View of  the TSA-102 on EM-11 mount.  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

B.  View of  the front element of  the triplet

C.  Another view of  the TSA-102, this time on a EM-200 mount, without the finder attached

Note that both 2" and 1.25" eyepiece adapters are included as standard, including a 2"

extension barrel.

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

A 28" long ABS case is available, which is  ideal for storage and transport.  Cases are supplied with no internal packing material. We recommend foam sheeting which is widely available at low cost.  With the dewshield retracted and the 2"/1.2" adapters removed the case is a perfect match for the TSA-102.  There is adequate space in the case for  the eyepiece adapters, finder/finder bracket, cradle and accessories.

See last page of  price list for dimensions and prices  of  ABS cases available.
