Accessories - Takahashi Mewlon-180C Instruction Manual

Here are major accessories conveniently usable with the Mewlon-180C.
◆ Diagonal Mirror 50.8mm (2") & Diagonal Prism 31.7mm (1¼")
When either of these diagonals are used with an eyepiece, the light path is longer to set
the secondary closer to the primary. In order to obtain sharp focus, use these diagonals as
indicated in the system chart. Refer to the illustration of the light path length.
When the accessories other than eyepieces
are used, the Diagonal Mirror is recommended
to use because the light path length is same
to that of the 50.8 (2") Extension Tube (L) and
thus it is almost not necessary to refocus.
Diagonal Prism 31.7(1¼")
◆ 4-Turret Eyepiece Holder 31.7D
The 4-Turret Eyepiece Holder 31.7D is
a convenient accessory that allows the
observer to use 4 eyepieces with different
magnifications and it is easily changed
by turning the turret. This turret accepts 4
different eyepieces and allows eyepieces to
be changed quickly by turning it. In addition,
this device has a built-in 90 degree prism
that allows to observer view the entire sky
conveniently.
