Short tube refractors are among the most versatile instruments at the disposal of today’s amateur astronomer. Canadian Telescopes’ 152mm achromatic refractor boasts the highest quality 6-inch lens and accessories for the most demanding astronomer, all at an affordable price. The CT152 delivers pinpoint stars and excellent color correction for observing and imaging, all in an easily transportable package. From public star parties to all-night astrophotography sessions, the CT152mm is a no-compromise, all-around solution for the astronomer who demands the very best.





There’s quality behind the lens as well, starting with a lens cell that allows collimation, should it ever be needed. The CT152’s tube is sturdy enough to hold that collimation and is baffled throughout, banishing stray light from your views and images. With its scratch-resistant glossy coating, the tube looks as good as it works. The CT152’s built-in mounting plate lets you mount it on your choice of any Vixen-style mounting system.





At the back end is a 3-inch Crayford focuser built to the most exacting specifications, allowing precision focusing and solid no-flex camera mounting that make focusing a pleasure. The focuser features a 4 kg capacity, rotating platform and separate fast and fine focus knobs, tension adjustment, locking mechanism and a compression ring to grip your eyepieces safely and securely without marring the barrel’s finish. From front end to back, quality is the focus of Canadian Telescopes’ CT152.





Whether you’re wandering through the Milky Way or imaging faint fuzzies, there is no substitute for quality. With Canadian Telescopes’ affordable CT152 there’s no reason to settle for less.
