The 1.25" AstroMaster Accessory Kit from Celestron features a selection of useful additions to your kit that will enhance your observational experiences. The two eyepieces produce medium and high magnifications in most telescopes, and the Barlow lens doubles the magnification of any eyepiece used with it - essentially doubling your inventory of eyepieces. Two of the most popular colored planetary filters, Red and Blue, can be used to enhance and highlight specific areas on Jupiter, Saturn, Mars, Mercury, Venus, and Saturn, as well as comets. For safe viewing of our closest celestial object, a Moon filter is also included with reduces glare and enhances contrast on the surface. To hold all these accessories is a hard plastic case with a custom-cut foam lining.
1.25" diameter barrels
Anti-reflection fully multi-coated to improve light transmission, color rendition, contrast and sharpness
15mm Kellner offers a medium magnification potential on most OTAs
6mm Plossl produces high-magnification
1.25" diameter barrel and eyepiece holder
2x magnification doubles the magnification of any eyepiece used
Increases magnification while preserving eyepiece's native eye relief for easier viewing at high magnifications
Built-in T-thread accepts optional camera-specific T-ring for high-magnification astrophotography/imaging
Tinted glass lenses ensure longevity
Anti-reflection coated to prevent glaring and ghosting
1.25" diameter to fit most standard 1.25" eyepieces
Threads allow filter stacking
Light blue with 30% transmittance
Most popular for the study of detail on Jupiter and Saturn
Enhances the contrast on Jupiter's cloud belts
Enhances details of the Great Red Spot
Brings out detail in Saturn's belts and polar features
Improves observation of Mercury's dusky surface markings at twilight, when it is near the horizon
Useful for increasing the contrast of dark shadings in upper Venusian clouds
Brings out the best definition in comet gas tails
Also very useful for lunar observing
Blocks the transmission of blue and green wavelengths
Sharply defines the contrast between the cloud formations and the lighter-toned surface features on Jupiter
Useful for definition of the Martian polar ice caps and maria, and sharpens the boundaries of yellow dust clouds
Improves observation of Mercury at twilight, when the planet is near the horizon; reduces the brightness
of the blue sky to enhance surface features when viewing during the day
Useful for studying bluer clouds on Saturn
Use during daylight observations of Venus to reduce brightness of blue sky; can make deformations of the terminator visible
21mm clear aperture
18% transmittance reduces glare to bring out more surface detail and improve contrast
Makes viewing the Moon safe when at or near full phase
