Overview: The Omni XLT 150 by Celestron is a high-quality
Newton Reflector telescope, designed for intermediate astronomers. The XLT 150 comes with
an Omni CG-4 Equatorial mount, a 25mm multi-coated eyepiece, a 6x30 finderscope,
a center leg brace that doubles as an accessory tray, and a heavy-duty tripod with 1-3/4" diameter stainless steel
legs and a built-in bubble level.
Newtonian Reflector: Newtonian Reflector telescopes replace
heavy lenses with mirrors to collect and focus the light, providing much more
light gathering power than refracting telescopes. It uses a single concave
mirror as its primary element. Light enters the telescope and travels to the
mirror in the back end. The mirror bends (focuses) the light forward to a single
focal point. A flat mirror (diagonal) intercepts the light and points it out the
side of the tube to the eyepiece. A Newtonian Reflector telescope offers such
impressive light-gathering characteristics you can view some deep space objects,
even with a modestly-priced unit.
Optics: The XLT 150 features high-quality optics with each
lens and mirror being hand selected. Only the finest grade of optical glass is
used. The premium Celestron StarBright XLT optical coatings provide maximized light transmission,
contrast, and image sharpness.
Eyepiece: The telescope comes with a 1-1/4" diameter, 25mm
multi-coated eyepiece (30x magnification) with 20mm eye relief and a 50° Field
of View. Higher power eyepieces are available for the XLT 150 to give you a
closer look at your chosen object. The unit comes with a 1-1/4" eyepiece adapter
installed on the unit. If you wish to use 2" diameter eyepieces, you can replace
the 1-1/4" adapter with the supplied 2" eyepiece adapter.
CG-4 Equatorial Mount: The included CG-4 equatorial mount
allows you to manually adjust the telescope and fine-tune the motion on both R.A.
and Dec. axes. There are slow motion knobs on each axis to make small
adjustments. The mount is equipped with ball bearings on each axis for smooth
performance. You can also make adjustments in altitude and azimuth alignment
with separate adjustment screws. To eliminate undue stress on the mount, the
telescope includes two counterweights to balance the unit: one is 7 pounds,
while the other is 4 pounds.
Finderscope: The telescope comes with a
6x30 finderscope which mounts to the outside front of the telescope tube to
help you aim the telescope at a distant target. The finderscope must first be
aligned with the telescope before use.
Included Software: Included with the telescope is "TheSkyX
-- First Light Edition" astronomy software on CD-ROM. The disc contains a 10,000
object database with printable sky maps and 75 enhanced images.
