Product Description
About This Item
Introducing the EdgeHD 11 Optical Tube Assembly CGE Dovetail Experience the universe in stunning high definition with the EdgeHD 11 Optical Tube Assembly CGE Dovetail. This aplanatic, flat field Schmidt-Cassegrain telescope is designed to provide you with aberration-free images across a wide visual and photographic field of view. Unlike other telescopes that only produce pinpoint stars across a curved focal plane, the EdgeHD optics guarantee visibly sharp stars across some of the largest CCD chips available today.
With our True Astrograph Quality, you can capture rounder, more pleasing stars that improve resolution and limiting magnitude compared to other telescopes of equal aperture. We've also taken mechanical features into consideration. The redesigned telescope tube not only optimizes the optical design, but also ensures that you get the most from your optics each and every night. The flexible tension clutches hold the mirror in place and reduce image shift during long exposure astro-images.
The cooling vents on the rear cell allow hot air to be released from behind the primary mirror, ensuring optimal performance. The EdgeHD 11 Optical Tube Assembly CGE Dovetail offers unparalleled versatility. At its native f/10, you can capture the smallest of deep sky objects with the necessary image scale.
Adding our optional reducer lens custom-designed for your size EdgeHD tube allows you to increase your field of view without sacrificing optical performance. You can also achieve high-resolution planetary, lunar, and solar imaging with the use of a Barlow. Additionally, all EdgeHD optical tubes are Fastar-compatible, allowing for ultra-fast f/2 wide field imaging when the secondary mirror is removed and replaced with a third-party lens accessory.
Rest assured that every EdgeHD 11 that ships has been individually tested to ensure the highest quality. Our rigorous quality assurance includes testing the surface quality of each optical component, as well as imaging tests with a camera and artificial star. This final acceptance test confirms that the EdgeHD 11 will perform in the field and deliver high-quality astroimages. Embrace the world of astrophotography and explore the cosmos like never before with the Celestron EdgeHD 11 Optical Tube Assembly CGE Dovetail.

Celestron Refractors EdgeHD Editorial Review
The EdgeHD 11 Optical Tube Assembly CGE Dovetail is a powerful telescope that provides high-quality visuals. However, it is important to note that it may push the Celestron CGEM mount to its limit for visual use and is not suitable for photography without additional support. If you are looking for a Celestron mount, it is recommended to consider the CGX mount or the discontinued CGEM DX or CGE Pro mounts. The telescope uses a vixen-style dovetail and may require an adapter for mounts that use CGE. The diameter of the OTA may vary depending on the specific model. When using the telescope with a Sky-Watcher EQ6-R mount, an interface adapter or replacement of the mounting plate is necessary. It is also advised to consider a slightly stronger mount for astrophotography due to the weight of the telescope.
