The StarSeeker IV 150mm Maksutov-Cassegrain GoTo
Telescope (#13166,
Figure 1) is a new addition to the
StarSeeker IV line and not included in the instruction manual
(IN 542 Rev A) for the StarSeeker IV series of telescopes.
It is similar to the StarSeeker IV 127mm Maksutov-Cassegrain,
but has a larger aperture optical tube assembly. One feature
specific to the StarSeeker IV 150 Mak-Cass is a 2" visual back
adapter with a 2"-to-1.25" adapter. This allows the user to use
either 2" or 1.25" diagonals and eyepieces with the 150mm
Mak-Cass, for added versatility
(Figure 2).
To install a 2" diagonal, first remove the 1.25" adapter by
loosening the two thumbscrews on the 2" visual back, then
insert the barrel of the diagonal. Secure it in place with the two
thumbscrews. Then insert an eyepiece into the diagonal and
secure it with the thumbscrew(s) on the diagonal.
To insert a 1.25" diagonal instead of a 2" diagonal, leave the
1.25" adapter in the 2" visual back, and insert the barrel of the
1.25" diagonal into the 1.25" adapter. Secure it in place with
the thumbscrew.
Warning:
Never look directly at the Sun through
your telescope—even for an instant—without a
professionally made solar filter that completely
covers the front of the instrument, or permanent eye
damage could result. Young children should use this
telescope only with adult supervision.
