Istar Optical Refractor Highlights

Unlike so many mass-produced telescopes on the market today, refractors from Istar Optical are created one at a time and then strenuously tested to insure the best quality possible. The optics are manufactured with glass from brand name companies like O'Hara, Schott, and CDGM.

Each Istar lens is produced with a super flat black-edge masking that eliminates unwanted inner objective glass reflections while improving on resolution. Once completed, all IStar lenses are tested twice. A computer interferometer test is done as well as a full visual test out under the stars. Every lens is engraved with its own serial number, and that number is linked to its set of reports, which are sent to the buyer along with warranty information (5 years).

A special lens cap is shipped with each telescope that will allow the user to increase or decrease the friction inside of the dew shield by simply loosening or tightening two silver bolts. It is unlike anything else on the market today.

The optical tube assembly and dew shield for each iStar telescope are produced in Austria and then CNC machined and powder coated in the Czech Republic. The finish of choice is matte black. The textured finish is durable and allows for a sure grip when handling the tube.

Finally, Istar provides a 2" dual speed, 360 rotatable focuser to finish off your telescope in style. The focuser is CNC machined of aircraft grade alloy, and the included 2" & 1.25" adapters have brass compression rings. The draw tube travel is 4.5", and the whole thing weighs 3.2 lbs.
