With the Barlow, the 40mm performs like a 20mm, the 32mm like a 16mm, and the 26mm provides the power of a 13mm eyepiece, giving you the flexibility to frame both wide star fields and closer planetary details.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e5 Planetary Filters for Enhanced Planetary Detail\u003c\/h3\u003e\n\u003cp\u003eEnhance your views of the planets with the five included 2\" colored filters.

1.25\"\u003c\/h2\u003e\n\u003cp\u003eThe Celestron Omni 4mm Eyepiece delivers high-magnification views through its 4-element Plössl optical system. Its 4mm focal length is designed to push the power limits of your telescope for detailed planetary observation, while the 50° apparent field of view frames targets with sharp contrast. The tight 6mm of eye relief is characteristic of high-power eyepieces, requiring close viewing to see the full field.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHigh-Magnification Viewing: A 4mm Focal Length for Planets and Double Stars\u003c\/h3\u003e\n\u003cp\u003eWith a 4mm focal length, this eyepiece is a specialist tool for nights of good seeing. It provides the high power necessary to resolve fine details like the Cassini Division in Saturn's rings, cloud bands on Jupiter, and the polar caps of Mars. The design is also ideal for splitting tight double stars and observing the compact cores of planetary nebulae.\u003c\/p\u003e\n\u003cp\u003eThis level of magnification requires steady atmospheric conditions and a well-collimated telescope to perform at its best. On a typical 8\" f\/10 Schmidt-Cassegrain, this eyepiece yields over 500x, a power reserved for the most stable nights. Its lightweight 1.26 oz (36 g) body ensures it won't create balance issues on your telescope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eContrast and Clarity: 4-Element Optics with Multi-Coatings\u003c\/h3\u003e\n\u003cp\u003eThe Omni 4mm uses a classic 4-element, 2-group Plössl design, a configuration known for producing sharp, high-contrast images with minimal internal reflections.

This is extremely high power, exceeding the generally recommended maximum of 400x for an 8\" scope. It will only be usable on nights with exceptionally steady atmospheric seeing.

Most eyeglass wearers will not be able to see the full 50° field of view while wearing their glasses. To see the entire field, you will need to remove your glasses and press your eye close to the lens, using the telescope's focuser to correct for your vision.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhy is the image through the Omni 4mm eyepiece dimmer than my lower-power eyepieces?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eHigher magnification spreads the same amount of light over a larger area, which naturally results in a dimmer image. This is a fundamental principle of optics.

1.25\"\u003c\/h2\u003e\n\u003cp\u003eThe Celestron Universal Barlow and T-Adapter is a single 1.25\" (32mm) accessory that provides three distinct functions for visual observers and imagers. This compact unit, with an external length of 76mm (3\"), functions as a 2x Barlow for visual use, a prime focus T-adapter for turning your telescope into a massive camera lens, and a \"tele-extended\" adapter that doubles photographic magnification. At a minimal weight of just 2.3 oz (65 g), it adds significant capability without impacting your telescope's balance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA 2x Barlow for Any 1.25\" Eyepiece\u003c\/h3\u003e\n\u003cp\u003eIn its default configuration, this accessory functions as a powerful 2x Barlow. Simply insert any 1.25\" eyepiece to instantly double its magnification, effectively turning a 20mm eyepiece into a 10mm. This is an economical way to expand your range of available magnifications without buying a full new set of eyepieces, and it maintains the comfortable eye relief of the original eyepiece.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eYour Telescope as a Prime Photographic Lens\u003c\/h3\u003e\n\u003cp\u003eFor astrophotographers, the Celestron Universal Barlow \u0026amp; T-Adapter converts into a prime focus adapter. By unscrewing the lower lens element, you are left with a hollow extension tube with T-threads on top. Attach a camera-specific T-Ring (sold separately), and you can connect your DSLR or SLR camera directly to the telescope's 1.25\" focuser, using your scope's native focal length to capture wide-field images of the Moon or terrestrial subjects.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA 2x Magnifier for Astrophotography\u003c\/h3\u003e\n\u003cp\u003eThe third configuration, known as tele-extended or \"Barlowed\" imaging, solves a common problem with fast refractors and Newtonian reflectors. These telescopes often lack sufficient inward focus travel to reach a sharp focus in prime focus mode. By reattaching the Barlow lens, the adapter pushes the focal point outward, allowing the camera to reach focus while also doubling the telescope's effective focal length for 2x larger images on your camera sensor.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat are the three ways I can use the Celestron Universal Barlow \u0026amp; T-Adapter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThis 1.25\" accessory serves three functions:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2x Visual Barlow:\u003c\/strong\u003e Doubles the magnification of any 1.25\" eyepiece you insert into it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrime Focus T-Adapter:\u003c\/strong\u003e After unscrewing the lens element, it connects your DSLR\/SLR camera (with a T-Ring) to the telescope, using the scope's native focal length.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\"Barlowed\" T-Adapter:\u003c\/strong\u003e It connects your camera to the telescope and uses the lens element to double the imaging magnification, which also helps achieve focus on scopes with limited travel.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eDo I need anything else to connect my camera with this Universal T-Adapter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes.
