The Celestron International 12017 CGEM EdgeHD SCT Goto Telescope is a powerful and versatile instrument designed for astrophotographers and serious astronomers seeking high-quality images and observations.
At its core, this telescope features a 12-inch Schmidt-Cassegrain optical system with an EdgeHD correcting lens. This combination provides exceptional image quality with sharp edges, reduced aberrations, and a wide field of view. The EdgeHD design also allows for faster focal ratios, making it an ideal choice for deep-sky imaging.
The CGEM equatorial mount is a German Equatorial Mount (GEM) with a high-precision, dual-axis encoder system. This ensures accurate tracking of celestial objects, even during long exposures. The mount is also capable of handling heavy loads, making it suitable for large telescopes and heavy equipment.
The CGEM EdgeHD SCT Goto telescope is equipped with a NexStar handcontroller, which makes it easy to locate and track over 40,000 celestial objects. The handcontroller also allows for simple alignment, making set up a breeze. The telescope also comes with a database of celestial objects, providing detailed information for each object.
The telescope features a dual-speed Crayford focuser, which provides smooth, accurate focus adjustments. The focuser is also equipped with a 2-inch 2-inch 2-inch adapter, allowing for use of various eyepieces, cameras, and other accessories.
The telescope comes with a heavy-duty steel tripod, which is sturdy and provides a stable base for the telescope. The tripod also features a built-in level, ensuring that the telescope is properly aligned.
The Celestron International 12017 CGEM EdgeHD SCT Goto Telescope is a high-quality, versatile instrument that is perfect for both visual and photographic observations. Its powerful optical system, accurate tracking, and user-friendly features make it an excellent choice for serious astronomers and astrophotographers.
Pros of buying Celestron International 12017 CGEM EdgeHD SCT Goto Telescope:1. High-quality optics: The Celestron International 12017 CGEM EdgeHD SCT Goto Telescope features a Schmidt-Cassegrain design, which provides excellent image quality with high contrast and sharpness.
2. GoTo mount: The telescope comes with a computerized GoTo mount, which allows for easy tracking of celestial objects. This is particularly useful for beginners who may not yet have the skills to manually track objects.
3. Durable construction: The telescope is made of high-quality materials, including a solid aluminum tube and heavy-duty steel tripod. This makes it a durable option that can withstand the elements.
4. Versatile: The telescope can be used for a variety of astronomical observations, including deep-sky objects, planets, and the moon. It also has a focal length of 2,500mm, which makes it suitable for astrophotography.
5. Easy to use: The telescope is easy to set up and use, with a simple interface for the GoTo mount. This makes it a good option for beginners who are just starting out in astronomy.
Cons of buying Celestron International 12017 CGEM EdgeHD SCT Goto Telescope:1. Expensive: The telescope is on the higher end of the price range for telescopes of this size. This may make it a less affordable option for some people.
2. Heavy: The telescope is quite heavy, weighing in at 44 pounds. This makes it a bit more difficult to transport and set up than some lighter telescopes.
3. Limited field of view: Due to its high magnification, the telescope has a limited field of view. This means that you may need to move the telescope around to observe different areas of the sky.
4. Complex setup: While the telescope is easy to use once it's set up, the setup process can be a bit complex for beginners. This may require some patience and practice to get the hang of.
Conclusion:The Celestron International 12017 CGEM EdgeHD SCT Goto Telescope is a high-quality option for serious astronomers and astrophotographers. Its computerized GoTo mount makes it easy to track celestial objects, while its Schmidt-Cassegrain design provides excellent image quality. However, its high price, weight, and limited field of view may make it a less affordable or practical option for some people. Ultimately, the best telescope for you depends on your specific needs and budget.
Recommendation:If you are a serious astronomer or astrophotographer with a budget to spend, the Celestron International 12017 CGEM EdgeHD SCT Goto Telescope is a great option. Its high-quality optics and computerized mount make it a powerful tool for observing and imaging the night sky. However, if you are a beginner or have a more limited budget, you may want to consider a more affordable and portable option. In that case, the Celestron NexStar 8SE or the Orion SkyQuest XT8 Classic are both excellent choices that offer similar capabilities at a lower price point.
Mechanical Features. Visibly sharp stars across large CCD chips. This guarantees you visibly sharp stars across some of the largest CCD chips available today. Cooling vents located on the rear cell allow hot air to be released from behind primary mirror.
While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with flat chip sensor a digital camera. Improved Performance. Add the optional reducer lens custom designed for your size EdgeHD tube and you can increase field of view without sacrificing optical performance. 40mm PLO's 1.25 Eyepiece.
Once focused, the flexible rods allow mirror to be held in place without putting any force or pressure on assembly, keeping image centered eyepiece or sensor. CGE Dovetail Rail. 2 Heavy-Duty Tripod. 1.25 Star Diagonal.
Next Hand Controller. With Celestron Star Bright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum. The optical system was designed to reduce more than just off-axis star coma; it also provides an historiography-quality flat focal plane all the way edge of field view. EdgeHD is the most versatile imaging telescope available today.
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 imaging system meets Celestron rigid assurance. Individually Tested. Two Year Warranty. The RMA# should be clearly inscribed on the shipping label.
9x50 Finder scope. Flexible tension clutches hold mirror and reduce image shift. In addition to Edgehd optimized optical design, the telescope tube has been re designed make sure you get most from your optics each and every night. Cooling vents release hot air from behind the primary mirror.
The heavens are teeming with life, but sadly, most of it is not visible to the naked eye. EdgeHD optics produce a focal plane more than three-times flatter standard Schmidt-Grosgrain telescope and dramatically competing coma-free designs. 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. Built-in All Star Polar Alignment.
Aberration-free images across a wide visual. Celestron CGEM II Mount CGEM Computerized GoTo Equatorial Mount. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. Now with the study of Astronomy and invention telescopes, moon, stars planets are all within reach.
Many optical designs that advertise themselves as historiographers actually only produce pinpoint stars across a curved focal plane. See the Universe in HD. True Quality.
