Frequently
Asked Questions
1.) What
types of telescopes does Takahashi make?
In addition
to their line of fluorite apochromatic refractors, Takahashi manufactures
superb reflecting telescopes for institutions and amateurs who want
instruments of higher quality with hand-made optics. These include
the Mewlon series of Dall-Kirkham Cassegrains, the CN-212 Classical
Cassegrain-Newtonian, the MT series Newtonian Telescopes, the BRC-250
Baker Ritchey-Chretien astrograph, and the Epsilon series of hyperbolic
astrographs.
2.) Why should
I purchase a Takahashi when other manufacturers offer larger aperture
instruments at a much lower price?
The answer is
simple: Quality! Takahashi instruments are made by hand to extremely
tight tolerances. Only the finest components are used and there
is a full five-year warranty on all mechanical and optical assemblies.
3.) Who makes
the best apochromatic refractors?
This question
is subjective. There are many quality refractors out there: Tele-Vue,
Astro-Physics, Carl Zeiss (Jena), Pentax, BORG, Thomas Back Telescopes,
etc. Each of these manufacturers has its adherents. We believe that
Takahashi makes many of the finest apochromatic refractors available
today. Different observers have different applications for their
telescopes. While one specific instrument may be better for a certain
application, another will be better suited to a different task.
Takahashi is currently the only regular manufacturer of fluorite
apochromatic refractors above 4" in diameter. Most optical experts
will agree that fluorite is the premier material for low dispersion
lens elements if price is not a consideration. One can read the
article "The Fluorite Advantage" for a further analysis of this
subject. Because Takahashi continues to use fluorite while other
manufacturers use ED (Extra-low Dispersion) glass, Takahashis generally
have an edge in overall brightness and contrast for visual observations
when compared with similar size instruments from other manufacturers.
