Bresser Messier NT-150L/1200 Hex-Focus Optical Tube Assembly

SKU: 4850120

The MESSIER NT-150 excells with high rigidity and tack-sharp optics. 150mm aperture enable you to observe bright nebulas in the depth of space. Find the remnants of a gigantic stellar explosion in the year 1054 in the constallation Taurus or scan the glowing bands of the Great Orion Nebula. Detect the famous Whirlpool Galaxy in the Big Dipper or find the Dumpbell-Nebula in the constellation Vulpecula. This telescope is only an optical tube without mount and tripod.


Please note: Reflector telescopes with optical design “Newton” are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.
