The Celestron C8 8-Inch Optical Tube Assembly delivers powerful, high-contrast views with a 2032mm focal length and premium StarBright XLT coatings, making it ideal for planetary observation and deep-sky exploration. Complete with a 25mm eyepiece, 6x30 finderscope, star diagonal, and a CG-5-compatible dovetail rail, this versatile Schmidt-Cassegrain OTA is ready to pair with your mount right out of the box.

• 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 95-micron 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/10, 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, 1.25” mirror diagonal for more comfortable viewing, and 40 mm Plössl 1.25” eyepiece are all included.

NOTE: The recommended solar filter for this scope for solar observing is the Astrozap Glass Solar Filter (Product No. 124451)
