Accessories - Takahashi FOA60-K Instruction Manual

Takahashi offers a wide variation of system parts for the FOA-60, including:
◆ Diagonal Mirror 50.8 (2")
◆ Diagonal Prism 31.7(1¼") MC
When the Diagonal Mirror or the Diagonal
Prism is used, the light path length will be
longer; so to get focus, you must turn the
focusing knob more. Attach the desired
accessories as instructed in the chart in
order to get sharp focus. The diagrams
shown at the right indicate the light path
length for reference. Please note that
some other 50.8 (2") eyepieces, from
brands other than Takahashi, cannot
focus.
◆ 4-Turret Eyepiece Holder 31.7(1¼") D
The 4-Turret Eyepiece Holder 31.7(1¼") D
is a convenient accessory that allows the
observer to use 4 eyepieces. This turret
allows eyepieces to be changed quickly by
turning it. In addition, this device has a built-
in 90 degree prism that allows the observer
to conveniently view the entire sky.
When the Extender 1.7XR, Extender ED
1.5X, or Extender Q 1.6X is used, be sure
to use the Extension Tube S also to ensure
sharp focus.
