About this product

Model:  iop_mak_6101
Part Number:  6101

150mm f/12 Rumak Maksutov-Cassegrain Telescope

An excellent choice for observing or imaging the Moon and planets. 

Fully multicoated f/12 Rumak Maksutov optics and interior baffles deliver high contrast views similar to a 5-inch apochromatic refractor, at a fraction of the cost! 

The only Maksutov telescope of its kind that includes a dual speed focuser for fine-tuning focus.  

Also includes an attachable aluminium dew shield (rare for a Maksutov telescope) for better performance in cold temperatures. 

 

Gregory vs Rumak

Gregory

Most Maksutov telescope available today (i.e. from Sky-Watcher, Celestron & Meade) are Gregory Maksutovs where the secondary mirror is a simple aluminised circle essentially glued onto the interior surface of the corrector lens. Therefore the curvature of the secondary mirror is always the same as the curvature of the corrector lens. From an optical design perspective this is a compromise but it does enable high contrast Maksutov optics to be manufactured at lower prices. 

Rumak

The Rumak Maksutov, named after its designer designer Harry Rutton, is a more sophisticated design. A Rumak's secondary mirror is distinct and separate from the corrector lens so the optical designer has more freedom to enhance performance. Typically, for the same focal length, a Rumak Maksutov has a flatter field and tighter stars when compared to a Gregory Maksutov. This makes the Rumak Maksutov an especially good choice for astrophotography.
