The Skywatcher SW 150N AZ4 150mm Reflector Telescope is easy to operate and very rewarding for casual astronomy. It delivers very good optical capability and rock solid stability. The Optical Capability of this Grab-in-Go 150mm Aperture Newtonian Rocks. The SW 150N offers 33% more light gathering than a 130mm mirror. The incremental aperture is sufficient to facilitate more serious viewing of fainter deep-space phenomenon. Prominent deep-space objects appearing as amorphous, ghost-like apparitions in smaller telescopes begin to reveal themselves as large aggregations of individual stars in the SW 150N-AZ4. Observing lunar and planetary detail with this telescope is beyond just being more satisfying, it can appear almost stunning in comparison. The perhaps 100,000 stars in M13, the spectacular globular star cluster in constellation Hercules, are almost completely resolved as discrete star points down to the central core, the Orion Nebula now appears as a large, billowing cauldron of hot gas and bright stars, as does the Lagoon and a number of other emission Nebulae. Galaxies while still very faint do appear noticeably brighter. The telescope shows exciting detail across the entire spectrum of solar system favorites. The Moon offers a number of interesting features about its rugged extraterrestrial landscape revealing smaller impact craters within larger high-walled craters, lunar mountains, plateaus, sea-like plains and other surface phenomenon.
