NexStar 9 1/4 GPS XLT STARBRIGHT

$3775.USD

Unique design, advanced features, GOTO accuracy, and superb optics. You get the picture.

Introducing the NEWEST member of the NexStar GPS family of fully-automated GOTO telescopes. Celestron’s 9 1/4” optical system has enjoyed a loyal following since we first introduced it with our Ultima 9 1/4” in 1995. Now the 9 1/4” optical tube is coupled with one of the most popular mounts in Celestron’s history — the NexStar GPS series.
The 9 1/4” was already a favorite among astrophotographers and discerning visual observers, but now with the carbon fiber tube and the NexStar GPS mount, it is a formidable addition to the NexStar GPS family. The 9 1/4” 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 a carbon fiber tube and Celestron's renowned StarBright ® multi-coatings. The NexStar 9 1/4” is compatible with the complete line of Celestron photographic and visual accessories.

What makes the NexStar 91/4” GPS great 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.
• Carbon Fiber Tube — 1/4 the thermal expansion of aluminum which creates a more stable focus. The Carbon Fiber tube is 4 times more resistant to temperature changes than aluminum tubes, thus minimizing your need to re-focus.
• Hand Figured Optics — Just like all other Celestron Schmidt-Cassegrain telescopes, the NexStar 9 1/4” 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.
• High quality Pittman® drive motors — Made in the U.S.A., PittmanLO-COG™ brush-commutated DC motors offer smooth, quiet operation and long life. The motor armatures are skewed to minimize cogging which is required for low speed tracking.
• 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. StarBright coatings are standard at no extra charge.

The NexStar 9 1/4” has all the features that make our NexStar GPS family so popular:

• Internal Slip Ring — NexStar’s power cables and telescope accessory cables will not get wrapped around the telescope.
• Integrated Handles — Carrying handles are integrated into fork arms to make lifting and transporting easier.
• Leveling — Leveling accuracy, which applies to both altazimuth and equatorial mounts, is accomplished by an internal switch that levels the base to an accuracy of 1 arcminute.
• Auxiliary Ports — NexStar’s auxiliary ports are located on top of the base which rotates as the telescope turns, preventing accessory cables from wrapping around the fork arms.
• Optical Tube Assembly Outer Rails — An outer rail on each side of the optical tube provides rigid, flex-free movement. The mounting tolerance on the front cell allows the outer rails to expand and contract independently of the optical tube assembly.
• 16-Channel GPS — NexStar’s GPS unit pinpoints your exact location on Earth, while downloading the date and Universal Time down to the second.88
• Hand Control and Software Features — 40,000+ object database. Features include: Compass Calibration, Polar Alignment Routine, Equatorial Auto Align, Database Filter Limits, Hibernate, Auto North and Level, Wedge Align Algorithm, Quick Align, and User-Defined Slew Limits.
