Explore Scientific designed their PN208 8" f/4 Carbon Fiber Photo Reflector Telescope with a large aperture and fast focal ratio to make it ideal for astrophotography and astro-imaging of near and deep sky objects. Included with the optical tube assembly is the motorized and computer controlled Exos-2 Go To mount with a 100,000+ database guidance system, dual-axis motors, a sturdy tripod, an illuminated pole finder scope, and a Crayford focuser with a 10:1 reduction for ultra-fine focusing capabilities. The optical tube assembly features a Newtonian reflector design with a 8" aperture and a f/4 focal ratio to make planets and the Moon to appear bright and clear while having the capacity to see out of the solar system to observe and image nebulae, galaxies, and binary stars.
The OTA is made of lightweight and strong carbon fiber. This material is highly resistant to temperature changes - such as moving from a warm house into a Fall night. Drastic temperature swings can cause metal OTAs to expand and contract, which can cause the delicate optics to move out of collimation over time. Its Crayford focuser uses a friction system to move the draw tube in and out, which enables much more precise focusing without backlash - an important feature in achieving tack-sharp images.
This version of the scope is equipped with the Exos-2 Go To motorized equatorial mount and helps to take the guess-work out of astronomy and gets you observing faster by combining an EQ mount with a 100,000+ database computer guidance system and dual-axis motors. To make set-up and alignment faster and easier, Explore Scientific includes an illuminated polar finder scope for use in the Northern Hemisphere. The included tripod is built with large 2" diameter stainless steel legs and tight tolerances to reduce vibration for clearer viewing. A center stabilizer bar pulls the accessory tray up to lock the legs in place adding further rigidity and vibration reduction. It is adjustable from 29 to 49" to accommodate a wide range of users. The mounting cradle-ring assembly clamps over the optical tube and lets the user adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balancing, while avoiding interference with other equipment.
The SkyTracker kit includes the hand controller unit, and right ascension and declination motors. Its hand controller has more than 100,000 objects with the ability for users to input custom coordinates and favorites. With a slew speed of 2°/second and nine tracking speeds the SkyTracker can accurately keep near and deep sky objects such as the Moon, planets, galaxies and nebulae centered in your eyepiece for long exposure imaging and astrophotography or prolonged observation sessions.
