Optical Tube Assemblies

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

NOTE: For solar observing the recommended solar filter is the Astrozap Glass solar filter 308-314 mm (Product Number 124447). This solar filter is a perfect fit for this OTA. 

Everyone loves a good mix and match so we can't see a reason why it doesn't apply to telescopes as well. Grab the saxon 90125 Observatory Cassegrain Telescope and mount it with an existing (or new) mount and tripod.

This telescope comes with the same great features as its 90125EQ counterpart, with an aperture of 90mm and a focal length of 1250mm. The compact and portable tube design means it's easy to store away when you're not outdoors observing planets and star clusters at night and terrestrial objects during the day.

Intermediate and advanced observers alike will enjoy the flexibility the saxon 90125 Observatory Cassegrain Telescope provides.
