Celestron's Night Vision Flashlight
is a purpose-built astronomy illumination tool, that uses two red LEDs
to preserve night-adjusted vision while providing light to set up,
read/write notes, change eyepieces, or navigate. Its combined rotary
variable brightness control/on-off switch allows you to adjust the
brightness over a wide range up to 25 lumens.
At the maximum
brightness setting, the emitted light is bright enough to locate dropped
items or disassemble your telescope after observing. The medium
brightness levels will properly illuminate a star chart without
affecting your pupil's darkness-adapted dilation. At the lowest
brightness setting, there's just enough light to determine a filter
designation or an eyepiece's focal length.
The Night Vision
Flashlight is powered by a single 9-volt battery that lasts for up to 12
hours on high and as much as 300 hours on low The supplied 20" (51 cm)
cord allows you to hang the light around your neck when not in use.
The Celestron Sky Map provides a fun way to read the night
sky, and is an ideal teaching guide. Just as you wouldn't set off upon a
road trip without a road map, you needn't try navigating the night sky
without a map either. Even if you're experienced around major
constellations, these maps help locate all kinds of fascinating objects.
The front cover has a specially designed luminous planisphere
that rotates to simulate the seasonal progression of celestial objects
through the sky. When the planisphere is pre-exposed to light, star
positions glow brightly against a dark background-mimicking actual
constellations. More than a thousand stars and deep-sky objects are
listed and charted. The illustrated reference section provides basic
information and the visual characteristics of various types of stars,
nebulae and galaxies.
To use, hold the map above your head with
the arrow facing celestial north. Turn the dial to the present date and
time, and the map shows you exactly what is above you. Turn the dial
as the hour changes to keep up with the orbiting sky show.
Please note - these maps are for use in the northern hemisphere only.
The 1.25" Celestron Variable Polarizing Filter
allows you to control the amount of light transmitted through to your
eye so you can tailor it to the brightness of the object you're looking
at—reducing the brightness and glare on celestial objects like the moon,
Venus, and even bright double stars.
This filter does not alter
the color of the object you're observing, making it a great choice for
astroimaging, especially when imaging the surface of the Moon. By
reducing the brightness, lunar details become more pronounced and
defined. This filter can also be used to darken the blue-sky background
when hunting for planets like Venus or Jupiter during daylight, making
the planet stand out from the background. Simply rotate the filter's
lower ring to adjust the light transmission from just 1% (blocking 99%
of incoming light) up to as much as 40%. Having this level of control
over the filtration allows you to precisely set it to a specific target
and current viewing conditions so you can get the best view possible.
Standard threads on both sides allow it to be installed on just about
any 1.25" eyepiece, and stacked with color or specialty filters to
further refine and enhance the viewing experience.
The Celestron AC to DC Power adapter
has a standard 2-prong North American power plug on a ~6' cord on one
end, and a 5.5mm circular DC output jack on a ~6 cord on the other side;
in between is a transformer box. The North American plug cord is
detachable from the transformer; the cord with the 5.5mm DC plug point
is permanently attached to the transformer. Output of this unit is
consistently 12 volts DC.
This allows AC 120-240V, 50-60 Hz AC
current supplies to power any of the Celestron telescopes with the 5.5mm
DC input on their drive base, a long list of items which includes the
Advanced, Celestar 8, CG9/11/14, CI700, CPC, CGE, NexStar i, NexStar SE,
Celestron NexStar i, NexStar SE, Ultima 2000 series and others.
erect image diagonals are Amici prism designs, allowing you to look
into the telescope at a 45° angle at images which are upright and
laterally correct. This is extremely comfortable for terrestrial
viewing or when sharing the viewing experience between those of varying
heights, and comes at the expense of a loss in brightness versus a 90°
diagonal-which would show images upright but laterally reversed.
Designed specifically for the unique needs of computerized telescopes, the Celestron PowerTank Lithium LT Power Pack
is built with a rechargeable lithium nickel manganese cobalt oxide
[Li(NiMnCo)O2] battery that delivers a steady charge over long periods
and requires less maintenance than traditional sealed lead-acid
batteries. A built-in 12 volt regulated circuit provides your telescope
with up to 8 hours of consistent power at the proper voltage for optimum
performance, and to keep your other gear like phones, cameras, or
handheld GPS units going while you're out observing there is a
rapid-charge USB port. Ideally suited for off-the-grid applications, the
housing is compact and lightweight so it won't take up a lot of space
in your kit. The PowerTank comes with a 6.5-foot telescope power cord
and an AC charger.
Ideal for near and deep-sky observation, Celestron's PowerSeeker 127EQ 127mm f/8 Reflector Telescope
features a respectable focal length and a large, parabolic mirror that
produce detailed images of the Moon, clear views of the planets, and the
ability to resolve bright distant objects such as nebulae and galaxies.
The scope is outfitted with a 1.25" rack-and-pinion focuser and two
eyepieces to get new users started, and a 3x Barlow lens that
effectively triples the magnification of any eyepiece used with it to
expand the usability.
The included manual equatorial mount
features slow-motion control cables with large knobs to make it easy to
track objects even when wearing gloves, while also minimizing vibrations
caused by handling the mount with your hands; and clearly visible
indicators on the Right Ascension and Declination axes. An
adjustable-height aluminum tripod rounds out the rig with a tray for
accessories such as eyepieces, filters, and lights.
The Celestron 90-Degree Mirror Diagonal (2") is a star diagonal with StarBright XLT coating, for use with Schmidt-Cassegrain telescopes with the 2"-18 threaded device.
diagonal is the term commonly associated with 90° mirror diagonals such
as this, which let you view objects that are at a 90° angle from the
direction the telescope is pointing. This allows quite comfortable
viewing when the telescope is at or near the zenith (directly overhead), and is fairly comfortable when observing terrestrial imagery as well-albeit a bit unorthodox at first.
erect image diagonals are Amici prism designs, meaning that images are
upright and laterally correct. This design, however, instead renders
images which are laterally reversed but are brighter than erect image
diagonals. This diagonal is used with 2" focusers and can be used with
either 2.00" or 1.25" eyepieces, thanks to the included adapter which reduces the eyepiece barrel diameter to accept the smaller size.
