Rowe-Ackermann Schmidt Astrograph with CGE Pro
Capturing impressive deep-sky astroimages is easier than ever with Celestronâ€™s new Rowe-Ackermann Schmidt Astrograph, the perfect companion to todayâ€™s top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system offers two huge advantages over traditional f/10 astroimaging: better apparent tracking and shorter exposures. That means youâ€™ll create better-looking astroimages in a fraction of the time, even without the use of an autoguider.
The Rowe-Ackermann Schmidt Astrograph builds on the legacy of Celestronâ€™s Schmidt Camera, which allowed astrophotographers to produce images on film in the 1970s.
Today, with CCD sensor sizes as large as filmâ€”or largerâ€”the Schmidt Astrograph offers a full 70 mm optimized image circle to capture pinpoint stars on the largest imaging chips. Combine this large image circle with a focal length of just 620 mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying, and even comet hunting.
The Rowe-Ackermann Schmidt Astrograph features newly designed optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle is unprecedented for an astrograph in this price rangeâ€”or even that of a much more expensive instrument. The design also provides minimal vignetting.
Advanced features like a custom engineered linear brass focuser bearing and FeatherTouch Micro Focus Knob allow you to make the fine adjustments you need to capture the perfect shot. Meanwhile, a12V MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube.
Engineered as a complete astroimaging system, every component of the Rowe-Ackermann Schmidt Astrograph is optimized for peak performance with DSLR and astronomical CCD cameras. Down to the thickness of the glass used in the included fully-multicoated optical window or an optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly.
Anchored by Celestronâ€™s best mount: CGE Pro
An observatory-quality astroimaging setup is well within your reach with Celestronâ€™s CGE Pro. Our flagship mount, CGE Pro is a rock-solid base for up to 90 lbs. of payload, including Celestronâ€™s Rowe-Ackermann Schmidt Astrograph, which weighs in at just 35 lbs. Feel free to add accessories, guidescopes, CCD cameras, filter wheels, and more; CGE Proâ€™s motors and 3-inch tripod legs will handle the load with ease. CGE Pro features all of Celestronâ€™s key technologies, including All-Star Polar Alignment, SkyAlign, StarBright XLT optical coatings, Fastar compatibility, and more.
