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.

Its 6-element optical system delivers a continuous range of magnifications with an apparent field of view that expands from 40° at 24mm to 60° at 8mm. The entire assembly weighs just 7.94 oz, making it a lightweight and efficient solution for finding, centering, and examining celestial objects without ever swapping eyepieces.\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\u003eThe 8mm to 24mm Variable Focal Length System\u003c\/h3\u003e\n\u003cp\u003eThis eyepiece's primary function is its ability to adjust magnification on the fly. Start at the 24mm setting for the widest possible view to locate and center your target.

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.

Its 47° apparent field of view is ideal for framing large deep-sky objects, and its massive 52mm of eye relief ensures viewing comfort for all observers. The optical system features multi-coated lenses and a 46mm field stop, maximizing light transmission and contrast on faint targets.\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\u003eThe 56mm Focal Length and 46mm Field Stop: Maximum True Field of View\u003c\/h3\u003e\n\u003cp\u003eThis eyepiece is engineered for one primary purpose: to show you the largest possible patch of sky your telescope can deliver. By combining a long 56mm focal length with a 46mm field stop—the physical limit of a 2\" barrel—the Omni 56mm becomes the ultimate finder eyepiece. In long focal length telescopes like Schmidt-Cassegrains or EdgeHDs, it allows you to frame entire targets like the Andromeda Galaxy (M31) or the Pleiades star cluster (M45) that are too large for higher-power eyepieces.\u003c\/p\u003e\n\u003cp\u003eThis low-power, wide-field capability is essential for locating objects and appreciating the grand scale of the Milky Way's richest star fields.

This long distance allows you to see the entire 47° field of view without pressing your eye against the lens. The integrated fold-down rubber eyeguard helps you maintain the correct viewing distance and blocks stray light, improving image contrast.\u003c\/p\u003e\n\u003cp\u003eWhile this extensive eye relief is a significant benefit, it can make eye placement sensitive for some observers.

Every air-to-glass surface is multi-coated to reduce reflections and enhance image brightness and contrast. To further improve performance on faint deep-sky objects, the internal barrel is blackened to absorb stray light, and the lens edges are blackened to prevent internal reflections from degrading the view.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreaded for Filters:\u003c\/strong\u003e The 2\" barrel is threaded to accept standard 50.8mm filters, allowing you to enhance views with nebula or light pollution filters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure Fit:\u003c\/strong\u003e A machined safety notch in the barrel helps prevent the 15 oz eyepiece from accidentally slipping out of the focuser if the thumbscrew loosens.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e The main body is machined from aluminum and features a knurled rubber grip for secure handling in all conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCelestron Omni 56mm vs. TeleVue 55mm Plössl: Key Trade-Offs\u003c\/h3\u003e\n\u003cp\u003eWhen choosing a low-power 2\" eyepiece, the Omni 56mm is often compared to the TeleVue 55mm Plössl.
