The popular 127mm planet caliper, manual and affordable!
The Bresser Messier 127/1900 EXOS-1 is the most affordable path to the popular 127mm Maksutov class. With a 1900mm focal length, you'll see the Cassini Division in Saturn's rings, cloud bands on Jupiter, and sharp lunar craters.


Maksutov optics: high contrast, no maintenance
The Maksutov design folds a 1900 mm focal length into a short, closed tube. The meniscus lens corrects the mirror almost completely: no chromatic aberration and a small central obstruction, resulting in high contrast. The 127 mm aperture with the included 26 mm eyepiece provides 73x magnification; consider around 254x as the maximum (f/15). Collimation is rarely needed, and the optics are virtually maintenance-free. Allow for 30 to 45 minutes of cool-down time: the closed tube needs to reach ambient temperature for the sharpest image.
The EXOS-1 mount
The EXOS-1 is an EQ-4 class equatorial mount. After aligning on Polaris, you track objects with the slow-motion cables. An RA motor is available as an upgrade.
Included
- Maksutov optics 127/1900

Featured accessories
The Bresser Plössl 10 mm eyepiece (190x, 29 euros) is the core magnification. The Bresser RA motor for EXOS-1 (155 euros) automatically tracks planets, and the polar scope for EXOS-1 (78 euros) speeds up alignment. An Omegon Premium moon filter (19.90 euros) dims moonlight.
For whom yes, for whom no
Good for: planet observers who want a 127mm class telescope without a GoTo budget. Not for: those who want automatic searching or deep-sky observing; choose the GoTo version or a Dobsonian instead.
