Takahashi - Sky 90 Apochromatic Refractor Optical Tube with Mounting Rings

The Sky 90 is the latest short tube fluorite apochomatic from Takahashi.  With a focal ratio of
f/5.56 and atube length of 13.8”, the Sky-90 is the most compact production apochomat. The newly
designed objective delivers very sharp color free images.

The Sky 90 is fully multicoated and uses knife edged baffles to produce the lengendary Takahashi
contrast. The 2.5” focuser and newly designed compression ring adapter allows the use of any
combination of 1.25” or 2” diagonal=ocular combinations.

When coupled with the f/4.5 flattener/reducer, the Sky 90 can be used as an astro camera or
ultra-wide field instrument. Not only is the Sky 90 an excellent choice for sky viewing, its very
short length makes it a portable high quality telescope for birding or for total solar eclipse
photography.

The Sky 90 fits easily into any airline overhead compantment. The optional rigid soft case
provides protection for this 7 lb. instrument. The Sky 90 is truly a compact and convenient world
traveler.
