BARLOW LENSES Barlow lenses offer an easy, economical way to increase the magnification range of your eyepieces, and Celestron carries an assortment of these highly useful lenses. A Barlow lens doubles the magnifying power of your eyepiece by doubling its effective focal length. For example, an 18mm eyepiece used with a 2x Barlow lens would have the magnifying power of a 9mm eyepiece. It’s like having two eyepieces in one!

DIAGONALS 1 Diagonals: .96" and 1/4" Celestron’s Erect Image Diagonals are an Amici prism design. This design allows you to look into the telescope at a 45° angle, at images that are oriented properly, meaning the image is upright and correct from left to right. Use of Celestron’s .96" 1 to 1 /4" 45° Erect Image Diagonal on a telescope equipped with .96" eyepieces means greater versatil- 1 ity. This diagonal will allow you to use 1 /4" eye- pieces, to obtain a larger field of view and better eye

FINDERSCOPES Finderscopes are secondary scopes, used to help locate objects in the main telescope. The larger the finderscope, the more you’ll see, to an upper limit of 50mm. Units larger than 50mm have too narrow a field of view to be useful. Finderscopes mount onto the main telescope tube and are an invaluable tool in locating objects for viewing. Clockwise: #93777, #93775, #93779, #93783-8 5x24 Finderscope – #93775 ™ An economical finderscope for Celestron’s Star Hopper Dobsonian telescopes.

FILTERS Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue. Celestron’s filters are made of high quality, solid plane parallel glass with excel- lent homogeneity. They’re anti-reflection coated to prevent glaring and ghosting. All eyepiece filters are threaded to fit Celestron’s, and most other manufacturer’s,

1 1/4" Polarizing Filter Set: – #93608 Ambient daylight is normally comprised of multiple wavelengths of light, vibrating in multiple planes. The Eyepiece Polarizing Filter Set transmits only light moving along a specific plane, thereby increasing the contrast between surfaces with different planar transmissions. Generally, the polarization effect makes blue skies a deeper blue, eliminates surface reflections and helps reduce atmospheric haze. The Polarizing Filter Set is intended for visual us

Solar Filters ® Celestron’s Solar Skreen solar filters transmit .001% of visible light, allowing direct observation of the sun. You can see sunspots and the mottled areas known as granules with these filters. In addition to reducing the intensity of the sun’s visible light, they also block 99.999% of invisible infrared light, so you can observe the sun in complete safety and comfort. The material used to make these filters is a strong, precision engineered, aluminized Clockwise: #94162, polyest

LPR Filters #94127A Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury, and both high and low pressure sodium vapor lights. In addition, they block unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow). As a result, Celestron LPR Filters darken the background sky, making deep-sky observation and photography of #9412
