Orion SkyScanner BL102mm TableTop Dobsonian Telescope

The new Orion SkyScanner BL102mm TableTop Dobsonian Telescope is now available from Orion Telescopes and Binoculars. The entry level telescope offers a compact, user-friendly design with simple up-down and left-right motion (“alt-azimuth”). The optical tube rotates smoothly in both axes, and each has a tension adjustment knob to let you set just the right amount of friction.

Orion SkyScanner BL102mm TableTop Dobsonian TelescopeOptically, the SkyScanner BL 102mm TableTop Reflector has a 102mm (4″) aperture primary mirror with a 640mm focal length (f/6.3). That means you’ll get bright, wide-field views that are easier to locate than with longer focal length telescopes. The included interchangeable 25mm Kellner and 10mm Plossl eyepieces provide 26x and 64x magnifying power, respectively that offer barrels that are threaded to accept optional Orion 1.25″ filters.

Also included is a 3x Barlow lens, which triples the magnification of any eyepiece it’s used with. It’s a great tool for getting in tight on your observing target. The non-magnifying red dot finder scope makes aiming the telescope a cinch. And to aid in your viewing of the most favorite celestial objects – the Moon – Orion is including the Orion MoonMap 260. It shows the locations and names of over 260 features on the Moon such as craters, mountains, valleys, and “seas”.
