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.
