$36.65 CAD$48.22 CAD2 in stock On saleBack Order / Waiting ListExplore Scientific: The Explore Scientific EXOS-2GT Equatorial Computerized Mount comes with a battery pack that holds eight D-cell batteries. While this is a nice back-up, we recommend you normally run the mount from a DC power source such as your car battery via its cigarette lighter, or a portable 12V DC Power Supply of your choosing (sold separately). This DC Adapter Cable will connect the Explore EXOS-2GT mount to either of these DC power sources.
p>Alternatively, if you have a source of AC power nearby, you can tap into it with the EXOS-2GT Universal AC Power Supply (EXOS2GTAC), sold separately. Many amateur astronomers like to own both types of power adapters so they can use the one that makes the most sense when out observing.

Explore Scientific 8x50mm Erect Image Illuminated Finder Scope [ES-VFEI0850-01]
$255.71 CAD$336.46 CADOn saleExplore Scientific: The Explore Scientific 8×50 produces a wide 6° field of view and allows precision focus of both main objective and eyepiece illuminated reticle. A precision polished roof prism produces images that are right-side-up, left-to-right correct. In other words, things are not upside-down and backwards like most viewfinders. The illuminated reticle is truly designed for finding objects with its open center (so you don’t mask the object you are centering with cross hairs) and scale markings for 1.5°, 3°, and 4.5° (the edge of the field of view is the 6° boundary). The 55° apparent field, long eye-relief eyepiece produces a bright 15.5mm exit pupil and will allow you to find faint galaxies, comets, and nebulae. All optics are fully-multicoated to insure maximum contrast.
