HMANE Telescope Reflector Main Mirror 1600mm with Secondary Mirror 40mm, Newton Reflector Spherical Mirror DIY Astronomical Telescope Mirror Kit, 226SQ59LARZVJE14JMZ8XR
Contains a primary lens with an objective lens diameter of 203mm and a focal length of 1600mm, and a secondary mirror with a short axis (short side diameter) of 40mm length. This is the core component of a set of mirrors..
Features: The main mirror is a spherical mirror with aluminized surface and a protective film to prevent scratches on the main mirror under light touch. The workmanship is excellent..
Advantages: Compared with cheap telescopes on the market, our primary mirror has a diameter of 203mm and a large-aperture optical glass with a focal length of 1600mm, which can see farther, and the focal length is as high as 1600mm, which can significantly reduce the imaging failure caused by spherical aberration. Real, greatly improved the experience, this is a professional DIY telescope lens set..
This kit has more collection and commemorative opinions. At the same time, the lens can support the famous schlieren experiment. It can make the home a laboratory in seconds, suitable for teaching, childrens hobby training, hands-on and other ability training..
Tips: For the fixation of the eyepiece, lens barrel, and fixed lens. You need to buy them by yourself..
Extends the focal length of your lens by 2x.This lens is only compatible with fixed focal length L-series lenses 135mm and over, as well as the EF 70-200/2.8L, EF 70-200/2.8L IS, EF 70-200/4L, and EF 100-400/4.5-5.6L.

Astromania Stereo Bino Viewer - Telescope Binocular Allows You to Adapt Two eyepieces to Your Telescope and View with Both Eyes simultaneously
Consisting of 7 elements, the Hyperion optical design delivers outstanding sharpness and color correction over its field.
Continuously variable focal length, with click-stops at 8, 12, 16, 20, 24 mm. Remains parfocal across zoom range. Click-stops enable precise focal length matching for bino-viewer use.
The field of view is 68 degrees at the 8 mm setting, and 50 degrees at 24 mm.
Excellent viewing comfort. The eye relief of 12-15 mm, large eye lens, and freedom from kidney beaning and blackouts result in a high level of comfort and ease-of-viewing, at all focal lengths.
Baader Planetarium has gone to great lengths to give the Hyperion Zoom the most advanced multicoatings ever used on amateur telescope eyepieces. The Hyperion Phantom Group multi-coatings truly rival the best in the world - including the famous Zeiss Abbe Orthoscopic.
