It prevents excess moisture in the air from forming condensation on the corrector lens. A dew shield also helps block stray light from entering the telescope for better viewing and astroimaging. Use the Dew Shield DX on your 6” and 8” Schmidt Cassegrain, EdgeHD, and RASA (with single dovetail) optical tubes with confidence.  \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConstruction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Dew Shield DX provides a perfect, custom fit designed specifically for 6” and 8” Celestron optical tubes.  The Dew Shield is built from durable PE plastic that is flexible but strong. Extra padding has been added at the tube attachment edge to create a stronger fit on the optical tube. The felt-lined interior absorbs any additional stray light and excessive moisture, creating optimal contrast when viewing and imaging.

With the focus motor installed, you can bring celestial objects into sharp, precise focus using your telescope’s hand controller or a computer instead of using the focuser knob. A focus motor is great for visual observers who want to dial in exact focus (especially those with dexterity issues) and a must-have accessory for astroimagers. With a motorized focuser installed, an astroimager no longer needs to be physically near the telescope to focus an image. Combined with computerized control of the mount and camera, the focus motor enables the imager to gather data remotely from a backyard observatory, or even a telescope located hundreds of miles away. As an added bonus, port covers protect the ports while not in use, and the covers cannot be lost due to the tethered design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible Optical Tubes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe focus motor is compatible with all SCTs from 6” to 14” in aperture that have been produced since the year 2006.

This incredibly fast f\/2.0 system is the perfect companion to today’s color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. Thanks to its fast focal ratio and patented optical design, you can produce sharp, detailed images and, in many cases, skip the autoguider completely.

With the 8” RASA joining the lineup, a wider range of astroimagers can enjoy the benefits of the RASA design. It has many of the same thoughtfully designed features as its “big brother” RASA 11, including the integrated air-cooling system, internal filter mount, and sturdy CGE dovetail mounting bar.\u003c\/p\u003e\n\u003cp\u003ePurely designed for imaging, the 8” RASA cannot be used visually.

View images on a computer instantly that are brighter and more detailed than can be seen in much bigger telescopes with the naked eye.\u003c\/p\u003e\n\u003cp\u003eBecause shorter exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. The 8” RASA’s relatively short 400mm focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required.

Focusing is easier, more accurate, and more stable than ever.  The key to the Ultra-Stable Focus System is a precision linear ball bearing, which is tested during assembly to ensure optimal results.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBuilt for Today’s Latest Cameras\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUnlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras. It is optimized for sensors with up to a 22mm diagonal, but performs well with sensors up to 32mm diagonal. The APS-C sized sensors used in many mirrorless cameras are a good choice. 42mm full frame sensors will also work, but performance will be poor at the edges of the sensor and field illumination will be reduced. Additionally, we do not recommend pairing RASA 8 with any camera body more than 4” in diameter.
