Agena's StarGuider Dual ED eyepieces are long eye relief eyepieces with a comfortably wide field for planetary observing that also give the sharpness, high contrast, and lack of lateral color and light scatter of the finest orthoscopic and Plossl designs. These can be used in any astronomical telescope that can accept standard 1.25 eyepieces. Unlike many more expensive eyepieces for planetary observing, the Starguider Dual ED 15mm eyepiece maintains an excellent eye relief of 20mm. With sixlens elements in this unique design, this eyepiece is fully internally baffled and all internal spacers have antireflection microbaffles on their edges with flat black anodizing to reduce reflections when viewing the Moon and bright planets. Every air to glass surface is broadband multi-coated for peak light transmission and outstanding contrast on subtle lunar and planetary detail. Spherical aberration of the exit pupil is well controlled, so there are no serious blackouts or kidney-bean effects if you move your eye slightly off the axis. The eyepiece has a twist-up eyecup that can be raised or lowered to provide the eye relief you find most comfortable. This eyepiece is parfocal with other focal lengths in this series, minimizing the amount of refocusing needed when switching from eyepiece to eyepiece. It is threaded to accept standard 1.25 astronomy filters and weighs approx. 6oz. Note that the color of the trim on the eyepiece may change at any time and may not exactly match the color depicted above.
B01066PM46 Availability: Currently unavailable Score: 6.757 Category: Electronics Rating: 5 Votes: 4 Find similar products Sky-Watcher Quattro 300P Imaging Newtonian - Large Aperture 12-inch Reflector Optical Tube for Astrophotography. The Quattro Imaging Newtonian is one of the most affordable telescopes with a f/4 focalratio. This astrograph is capable of producing an exposure 6x faster than any f/10 optical tube.Even pricey refractors have trouble reaching a focal ratio this fast. Using a faster optical tubewill shorten the exposure time, giving you more time to photograph nebulae, clusters, and otherdeep sky objects.Like all Sky-Watcher reflectors, our Quattro Imaging Newtonian features aluminum-coated borosilicate mirrors with a quartz overcoat, producing 94% reflectivity. The opticalsystem uses an oversized secondary mirror, providing greater illumination for DSLRs and CCDsusing full-frame sensors. The optical tube is constructed with rolled steel, and features Sky-Watcher’s signature metal-flake Black Diamond finish on the exterior. The interior of the opticaltube uses knife-edge baffles to absorb any stray light from ruining your images.As customary with all Sky-Watcher telescopes, a boat-load of accessories are bundledwith the optical tube. First is a 2-inch dual-speed 10:1 focuser with included 1.25-inch eyepieceadapter, which provides flexibility for either 1.25-inch or 2-inch eyepieces. Also included aretube rings and a V-style dovetail plate, as well as a 9x50 finderscope. For photographerslooking to create a flat field and eliminate vignetting, an optional coma corrector is availableseparately. Parabolic mirrors normally produce some aberrations around the edge of the field ofview (coma), so this corrector is highly recommended for users with large imaging sensors and full-frame DSLRs.

B01LWSZVNS Availability: Currently unavailable Score: 6.098 Category: Electronics Rating: 4.5 Votes: 4 Find similar products Celestron CGEM II 800 EdgeHD 8 Schmidt-Cassegrain Telescope. CGEM II 800 HD combines Celestron's newly redesigned CGEM II computerized equatorial mount with its acclaimed EdgeHD optical system. With 8 inches of aperture and our premium StarBright XLT coatings, the CGEM II 800 HD gives you over 800 times the light gathering power than the unaided eye and is the lightest and most portable telescope in its class. OPTICAL TUBE INFO: See the Universe in HD EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view. True Astrograph Quality Many optical designs that advertise themselves as astrographs actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today. Learn more about EdgeHD technology. Improved Performance Superior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestronâs StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum. Mechanical FeaturesIn addition to EdgeHDâs optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night. Mirror clutches- Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor). Tube vents- Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 50-mesh filter guaranteed to let warm air out without letting dust in. Fastar versatility- EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lensâcustom-designed for your size EdgeHD tubeâand you can increase your field of view without sacrificing optical performance. A Barlow lens gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are 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. Individually Tested Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This âfinal acceptance testâ confirms the EdgeHD will perform in the field and deliver high-quality astroimages. MOUNT INFO: A fresh update to the venerable CGEM mount, the CGEM II has a fresh, attractive, bold appearance and is capable of carrying Celestronâs higher-end SCT optical tubes (up to 11) securely and vibration free, which is ideal for both imaging and visual observing. Capable of holding 40 lbs. of payload and slewing at 5Â° per second, you will be able to instantly point to any of the celestial objects in the database. ERGONOMIC DESIGN CGEM II was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment. The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up. INNOVATION The CGEM II series features Celestronâs innovative Polar alignment procedure called All-Starâ¢. All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CGEM II sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will allow users to train out the worm gears periodic errors, while the mount retains the PEC recordings. PERFORMANCE For objects near the Meridian (imaginary line passing from North to South), the CGEM II will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM II mount has a robust database with over 40,000 objects, 100 user defined programmable objects and enhanced information on over 200 objects. Celestron's CGEM II mount is the perfect fit between the Advanced Series and CGE Series. Offering the portability of the Advanced Series and the precision of the CGE.
