Celestron CPC 925 GPS (XLT)
|
|
Outline
|
Celestron’s 9.25” optical system has enjoyed a loyal following since
first introduced with the Ultima 9.25” in 1995. Now the 9.25” optical
tube is coupled with Celestron's newest computerized telescope family —
the CPC GPS series.
The 9.25” was already a favourite among astrophotographers and discerning
visual observers and it offers 33% more light gathering than the 8" model.
The CPC 925 GPS was specifically designed for visual infinity focus when
using 2" eyepieces and has an optimized baffle system to benefit
astrophotography by minimizing vignetting at the edge of the field of view.
Its longer primary focal length and lower magnification secondary mirror
contribute to a flatter field of view at the focal plane and helps to
further reduce optical aberrations.
This feature packed model comes standard with Celestron's renowned StarBright
multi-coatings. The CPC 925 GPS is compatible with the complete line of
Celestron photographic and visual accessories.

Suited for Astrophotography
|
-
Longer focal length primary and lower magnification secondary— Contributes to a
flatter focal plane with less coma and off-axis astigmatism.
-
Baffle design —Optimized for astrophotography. Minimizes vignetting at the edge of the field of
view. This reduces light drop off at the corners of your film plane.
-
Hand Figured Optics — Just like all other Celestron Schmidt-Cassegrain telescopes, the CPC 925 GPS optics are individually matched and hand figured to ensure the highest optical quality in every telescope.
-
Focus mechanism — At the heart of Celestron's Schmidt-Cassegrain focus mechanism are pre-loaded ball bearings, not bushings, minimizing focus shift.
-
Heavy-duty die cast aluminum fork arms —For maximum rigidity.
-
Unique roller bearing design bearing and shaft —The telescope base rotates around a wide 9.5” track for maximum stability; especially important when equatorially mounted for imaging.
-
Autoguider port — For interfacing an autoguider or a drive corrector for long exposure imaging or astrophotography.
-
StarBright coatings — High quality multi-layer coatings maximize transmission of light to the film plane.

Celestron's new CPC Series with revolutionary SkyAlign Alignment
-
Technology re-defines everything that amateur astronomers are looking for — quick and simple alignment, GPS, unsurpassed optical quality, ease of set-up and use, ergonomics, enhanced computerization and, most important, affordability.

|
|
|
Internal GPS
|
The CPC Series' internal GPS receiver automatically downloads the date and
time from orbiting satellites and pinpoints its exact location on Earth.
This eliminates the need for you to manually enter the date, time, longitude
and latitude.
|
|
|
|
Celestron's SkyAlign
|
Once the CPC's internal GPS has established the telescope's position, aligning
the telescope is as easy as 1-2-3! Simply locate and use hand control to manually
point (slew) the telescope to three bright celestial objects. You do not need
to know the names of the stars — you may even pick the moon or bright planets!
Celestron's NexStar® software technology will model the night sky to determine
the position of every star, planet and celestial object above the horizon.
Once aligned, the remote hand control allows direct access to each of the celestial
catalogs in its user-friendly database.
|
|
|
|
Celestial Object Database
|
The CPC database contains over 40,000 celestial objects including Messier objects,
the Caldwell Catalog, as well as NGC Galaxies, nebulae and planets. User-definable filter
limits make navigating through this expansive database quicker and easier. Filter Limits
let you filter out objects that are outside of your local horizon (ie, if trees or
mountains were in the way).
Identify feature tells you what you're looking at, but it can also be a very fun
way to tour around the sky. Just point the telescope up somewhere and ask it to
identify Messier objects (for instance) and it will show you the 5 nearest Messier
objects to your position and let you GOTO them. You can keep doing this for different
parts of the sky or for different object types -- it is a lot of fun.
There's also "Solar Sys Align" that lets you align on the sun or moon for daytime observing
-- it is easy to use this to see planets or bright stars in the day.
