The 1.25"" Celestron Astro Master Kit contains a vast selection of key observational accessories to take your stargazing to the next level. The two available eyepieces produce both medium & high magnifications in the majority of telescopes, whilst the Barlow lens doubles the magnification of the eyepiece. The included Red & Blue planetary filters stand as two of the most popular coloured filters used within astronomy. They work by enhancing & highlighting specific areas of Jupiter, Mars, Mercury, Saturn, Venus, & even larger comets. For an upgraded & safer view of the closest celestial object to Earth, a Moon filter is also included that actively reduces glare & intensifies contrast on the surface. All accessories can then be housed in the hard plastic case, which is made up of custom-cut foam lining to suit each individual observational tool.
