Celestron also offers a complete line of rugged, but soft Foamex plastic lens shades that can be put away flat after usage. They use a thicker material and won't crack easily as other manufacturer's products do. The quality level is a step above all others as all material is sewn (not glued in some places) for a long life.

Your telescope's focuser is used to compensate for your near- or far-sightedness; DIOPTRX compensates for your astigmatism. These units attach and lock onto the tops of over 20 long eye-relief Tele Vue eyepieces to achieve the sharpest full-field viewing possible. DIOPTRX models are available in 1/4 diopter steps, from 1/4 up to 3.5 diopters, and are rotatable for tuning to the best orientation. A series of engraved letters on the barrel helps to monitor orientation. Simply choose the DIOPTRX model that matches your eyeglass prescription for astigmatism. All lenses are multi-coated glass in anodized aluminum housings with rubber eyeguards The visual experience in astronomy is maximized by stripping away limitations: the limitations of the observing location (dark skies and steady seeing) the limitations of the telescope (aperture, field, resolution and contrast) the limitations of the eyepiece (field, resolution and contrast) the limitations of our eyesight (e.g., astigmatism) Tele Vue has historically been dedicated to overcoming the first three of these limitations: with wide angle, flat field telescopes easily portable for traveling to great observing locations matching ultra-wide angle eyepieces with full field image quality to generate what we call "spacewalk" viewing and a variety of long eye relief eyepieces to allow eyeglass wearers to enjoy the maximum visual experience To overcome the fourt

Properly designed Barlows do wonderful things. First, they amplify power while retaining the eyepiece's eye-relief. Second, they slow the telescope's f/#, which improves eyepiece sharpness. Third, the designer can introduce compensations for eyepiece aberrations. Tele Vue's 1 1/4" 2x and 3x Barlows were envisioned as magnification windows. Multi-coated high index glasses assure optimum aberration correction, exceptional contrast and virtually no light loss. Tele Vue Barlows achieve their design goals even when tested by the fastest scopes. The Tele Vue design approach includes mechanical conveniences. The Barlows are parfocal with Tele Vue eyepieces. The 3X Barlow is threaded for 1 1/4" filters.

Third, the designer can introduce compensations for eyepiece aberrations.Tele Vue's 2" 2x BIG Barlow, 1 1/4" 2x and 3x Barlows were envisioned as magnification windows. Multi-coated high index glasses assure optimum aberration correction, exceptional contrast and virtually no light loss. Tele Vue Barlows achieve their design goals even when tested by the fastest scopes. They even improve our competitor's eyepieces and telescopes!For eyeglass wearers, the Big Barlow is perfect for doubling the power while retaining the eye-relief of 2" Tele Vue eyepieces such as the 55mm Plossl, 35mm and 27mm Panoptics (requires use of Panoptics Barlow Interface) and 20mm Nagler Type 2.Our design approach includes mechanical conveniences. The Barlows are parfocal with our eyepieces and the BIG Barlow includes a parfocal 2" - 1 1/4" adapter. The BIG Barlow is threaded for 48mm filters and has a captive lock-screw. Both 1 1/4" Barlows are threaded for 1 1/4" filters.Barlows do more than just increase magnification; they also retain eye relief (or in the case of long focal length eyepieces, actually INCREASE eye relief). A high quality Barlow must be properly designed and manufactured in order to avoid compromising a telescope's color correction and spherical aberration corr

Conveniently watch planets stars and moon with the Celestron Powerseeker 1000x127 mm Reflector Telescope. You can either mount it as an equatorial or altazimuth mount design for terrestrial and astronomical viewing. The Celestron Powerseeker 1000x127 mm Reflector with a full range of eyepieces plus a 3x Barlow lens enhances viewing power to give better image details. To resolve the faint detail of the deep-sky and other celestial objects the Celestron 21049 Powerseeker Telescope has a larger aperture and greater light gathering capability. The image quality is further enhanced with the telescope’s coated glass optical components.
