Before you embark on your next stargazing adventure, consider the 8" EdgeHD Optical Tube Assembly with Starbright XLT Coatings and CGE Dovetail slide bar. This advanced Schmidt-Cassegrain telescope offers an aplanatic, flat field design that ensures aberration-free images across a wide visual and photographic field of view. Unlike many optical designs that claim to be "astrographs", the EdgeHD Optical Tube Assembly goes beyond producing pinpoint stars across a curved focal plane. It provides an astrograph-quality flat focal plane right to the edge of the field of view. This feature guarantees visibly sharp stars across some of the largest CCD chips available today, making it an ideal choice for digital camera use. The EdgeHD optics produce a focal plane that is more than three times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This superior edge performance not only creates rounder, more pleasing stars but also improves the resolution and limiting magnitude when compared to telescopes of equal aperture. The telescope tube has been redesigned with mechanical features to optimize your viewing experience. It includes mirror clutches with flexible tension that hold the mirror in place and reduce image shift during long exposure astro-images. The tube also features cooling vents on the rear cell, allowing hot air to be released from behind the primary mirror. Each vent has an integrated 50-mesh filter to ensure that warm air can escape without letting dust in. The EdgeHD Optical Tube Assembly is the most versatile imaging telescope available today. It is Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third-party lens accessory for ultra-fast f/2 wide field imaging. Every EdgeHD that ships has been individually tested for the surface quality of each optical component, as well as with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This final acceptance test confirms that the EdgeHD will perform in the field and deliver high-quality astro-images. Whether you're an amateur astronomer or a seasoned professional, the 8" EdgeHD Optical Tube Assembly with Starbright XLT Coatings and CGE Dovetail slide bar is a high-quality, durable, and sophisticated tool for viewing and observing celestial objects in the night sky.

Celestron 11" Rowe-Ackermann Schmidt Astrograph RASA Optical Tube, Version 2
4499 USD
Capturing impressive deep-sky astroimages is easier than ever with Celestron's Rowe-Ackermann Schmidt Astrograph (RASA) V2, the perfect companion to today's top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system allows for shorter exposure times compared to traditional f/10 astroimaging, without sacrificing resolution. Because shorter sub-exposure times are possible, your equatorial mount won't need to accurately track over extended periods. The short focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required. RASA 11 V2 builds on the legacy of Celestron's Schmidt Cameras, which allowed astrophotographers to produce images with much shorter exposure times on film in the 1970s. Today, with CCD sensor sizes as large as film or larger, the RASA 11 V2 offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips. Optical performance for huge sensors with diagonals of up to 52mm wide is still excellent. Combine this large image circle with a focal length of just 620mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying, and even comet hunting. Optical Performance The RASA 11 V2 features 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 are unprecedented for an astrograph in this price range or even that of a much more expensive instrument. The design also provides minimal vignettin Advanced Features RASA 11 V2 utilizes the new Ultra-Stable Focus System (USFS). At the heart of this system is a precision linear ball bearing. The bearing serves to minimize focus shift (unwanted lateral motion of the primary mirror during focusing which causes shifting of the image) and mirror flop (movement of the primary mirror when the telescope is pointing to different positions in the sky). The USFS is also compatible with the optional Celestron Focus Motor (#94155-A). The integrated 12V DC 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 RASA 11 V2 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 optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly. The Dovetail CGE bars on the top of the optical tube provides a connection for use of optional accessories like a guidescope.
