Bresser Messier NT-150s/750 Hex-Focus Optical Tube Assembly

SKU: 4850750

The BRESSER Messier N-150s excels with tack-sharp parabolic optics. The 150mm aperture enables you to observe bright nebulas in the depth of space. Find the remnants of a gigantic stellar explosion from the year 1054 in the Taurean constellation, 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 (little fox). 

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.
