I purchased these astronomy equipment from High Point Scientific last summer. Really solid telescope for moon. I have used this a handful of times in my driveway and is in like new condition. The Skywatcher Skymax 102 mm sells for $355, Williams Optics Dielectric Diagonal sells for $140, Apertura 8x50 Right Angle Finderscope $75, custom dew shield $30, new this would set you back $600 plus tax. This set includes the Apertura finder scope, Williams Optics diagonal, The two Kellner 10mm+25mm eyepieces, diagonal and finder scope that came with the scope. I never used those items and i have the all retail boxes the scope and items came in.
Maksutov-Cassegrain telescopes are all about portability, sharp, contrasty images, and the flexibility to use them as a telescope for astronomy, a spotting scope for terrestrial use, a lens for photography, or a travel companion for all three! The Sky-Watcher 102 mm Maksutov-Cassegrain is just 11” long and weighs 4.25 lb., but it uses a 4” lens system to do the job of gathering light so you can see faint objects millions of light years away. The classic long focal length of f/12.7 will give you inky dark background skies so that celestial targets stand out beautifully.
The Skymax 102 comes with a nice selection of accessories, including a 1.25” 90-degree star diagonal, two 1.25” Kellner eyepieces (10 mm & 25 mm), a red dot finder for easy location and centering of objects, and a Vixen-style dovetail plate, which allows you to mount your telescope on a wide variety of alt-azimuth or equatorial mounts.
