Solar Warning
  • Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
  • Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
  • Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.

  • Experience our best optical performance with EdgeHD’s aplanatic, flat field Schmidt-Cassegrain optics for pinpoint stars all the way to the edge of today’s largest imaging sensors and widest eyepieces

  • Aluminum optical tube with tube vents featuring an integrated 50-mesh filter allows hot air to be released from behind the primary mirror. Mirror support knobs hold the mirror in place and reduce image shift during imaging

  • Versatile design accommodates 3 focal ratios: native f/11, f/7 with the addition of a focal reducer, or ultra-fast f/2 imaging with a removable secondary mirror and third-party accessories

  • Celestron’s premium StarBright XLT coatings provide maximum light transmission

  • A 9x50 finderscope, 2” mirror diagonal for more comfortable viewing, and wide-angle 23mm Luminos 2" eyepiece are all included
