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
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.
