Celestron AstroMaster Accessory Kit

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 coloured 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.

Eyepieces

1.25" diameter barrels

Anti-reflection fully multi-coated to improve light transmission, colour rendition, contrast and sharpness

15mm Kellner offers a medium magnification potential on most OTAs

6mm Plossl produces high-magnification

Barlow Lens

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

Filters

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

#80A Blue:

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

#25 Red:

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 the 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 the brightness of blue sky; can make deformations of the terminator visible

Moon:

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

Also useful to bring out surface details on Venus
