This 2" Astro-Tech first-surface mirror star diagonal has state-of-the-art 46-layer dielectric mirror coatings for a full 99% reflectivity, higher than the 88% of a conventional aluminum diagonal or the 97% of an easily-tarnished silver diagonal. The durable ion-deposited dielectric coatings on the mirror's finely-polished 10mm thick BK7 optical glass substrate also provide higher contrast and resolution during critical planetary, lunar, and binary star observations. This Astro-Tech diagonal is, quite simply, unique among premium-quality 2" star diagonals for its exceptional value.
The mirror housing is precision-machined from solid aluminum, rather than simply flimsy plastic or a sheet metal stamping, as you'll find with ordinary diagonals. A rigid U-shaped die-cast metal backplate with stainless steel hardware holds the mirror in perfect optical alignment in the machined body. The solidity of the construction is mirrored in the diagonal's substantial 17 ounce weight. The interior of the body is lined with light absorbing materials, in addition to being anodized an antireflective matte black. The 2" focuser-side barrel is also anodized antireflective matte black, and is internally antireflection threaded for even higher contrast. The barrel is threaded to accept standard 2" filters.
Rather than using a metal thumbscrew that contacts eyepiece barrels directly and can scratch them, the diagonal's 2" eyepiece holder uses a non-marring soft brass compression ring to secure 2" eyepieces and the standard equipment 1.25" eyepiece adapter in place. The knurled and chromed thumbscrew that operates the compression ring is a full 1/2" in diameter, twice that of competitive diagonals. This provides a sure grip in cold weather when wearing gloves or mittens. A slanted groove cut into the outside of the focuser-side 2" barrel engages with the scope's focuser drawtube thumbscrew to act as a safety stop. This keeps the diagonal from..Read More
Meade's Series 4000 QX Wide Angle is a new line of 5 element eyepieces designed and engineered for high-performance observing. They yield a super wide 70 degree apparent field of view with extreme resolution. This is one of the few eyepieces sold today that can give you a wide field of view with a consistent pinpoint edge-of-field sharpness and long eye relief. All QX Wide Angle Eyepieces feature multi-layered optical coatings to maximize light transmission, and edge-blackened optics for superior image contrast. The new Meade Series 4000 QX Wide Angle eyepieces are an incredible value, delivering excellent performance.

- Magnification power from 30x to 200x
- See the Rings of Saturn!
- Explore deep space/nebulas!
- Telescope Size: 28.8" x 9.7" x 10.6"
Aperture: 12-Inch. Focal Length: 3048mm. Focal Ratio: f/10. UHTC Coatings, 1.25-Inch Diagonal Prism. LX90-SC Meade¹s Schmidt-Cassegrain (SC) optics give you high performance for the best possible price. For the person looking to get the most from their astronomical dollar, look no further. Meade uses water-white glass with superior light transmission across the entire visible spectrum, unlike inferior standard plate glass used by other telescope manufacturers. Combined with our industry-leading Ultra-High Transmission Coatings (UHTC) -- with 15% better light transmission than standard coatings -- and oversized, thermally-stable Pyrex primary mirrors for optimum light collection, you get a spectacular viewing experience not available on comparable competitors¹ telesscopes. GPS - LX90 can do more than track satellites. It talks to them as well. Turn it on and the built-in Sony GPS sensor immediately determines your precise date, time and location. AutoAlign then uses this info to align your scope for a tour of the most spectacular sights in the universe. EASY ALIGN –LX90s are smart scopes that know the night sky right out of the box. Easy Align picks two alignment stars for you and places them right in your viewfinder. Just center them to fine tune your alignment and the wonders of the universe are at your fingertips. OVERSIZED PRIMARY MIRROR – Only Meade manufactures their primary mirrors in diameters larger than their listed aperture (e.g. the diameter of the 8-Inch LX90’s primary mirror is actually 8.25-Inch).This additional 1/4-Inch yields a wider, fully illuminated field-of-view, and allows you to see the light other telescopes leave behind...Read More

The 1.25" Variable Universal Camera Adapters allow attachment of a camera body to reflector and refractor telescopes for either prime-focus or telescope eyepiece-projection photography (hence the term "universal"). The adapter slides into the eyepiece holder as an eyepiece normally would. This universal adapter is composed of two detachable parts: a prime-focus adapter (or "T-adapter") for prime-focus photography, and a fixed-length or variable extension tube for eyepiece-projection photography. A thumbscrew in the extension tube holds the telescope eyepiece in place. This combination of prime-focus and eyepiece-projection camera adapter has a sliding barrel design that allows variable projection distances. This allows for slight changes in magnification without swapping telescope eyepieces when performing eyepiece-projection photography. Fits reflector and refractor telescopes with 1.25" eyepiece holders. This Variable-Power Universal Camera Adapter is precision made of black-anodized aluminum and is compatible with 1.25" telescope focusers and many 1.25" telescope eyepieces (some eyepieces have housing diameters that are too large to fit inside the adapter). The barrel of the adapter is threaded for filters. A T-ring for your specific camera model (sold separately) is required to couple your camera body to the universal adapter...Read More
