A Second Zambuto scope4th January 2015 An 8" newtonian with a Zambuto mirror came up for sale on Astro Buy and Sell I could not resist. The mirror is quartz and thinner than most 8" mirrors which should give a quick cool down time. It came with an Orion Optics dobsonian mount which makes it ideal for a visual scope on the patio. There were also tube rings for mounting on an EQ6 type mount. The secondary is a 1/30 wave from Antares Optics and is only an 18% obstruction. This also is ideal for visual work on the Moon and the planets. The spidervanes are curved - no diffraction spikes. The main mirror support is a cnc machined one from Orion, and the focuser is a Revelation Crayford. The weak link is the metal tube which has a few small dents and will probably benefit from flocking. |
