Celestron EdgeHD 1100 OTA - 280 mm f/10 Flatfield SCT

Celestron 1100 EHD 11" Optical Tube Assembly

The EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view.

The Celestron XLT multi-coating enhances constrast and brightness even further, for astrophotography as well as for observation. We recommend the EdgeHD for astrophotographers and for dedicated observers who want to use a large aperture as mobile unit.

With 12.7 kg tube weight, the EdgeHD 1100 can still be used mobile. It can be held by a Celestron CGEM mount or the CGEM-DX, even for astrophotography. However, the telescope also makes a good impression in compact obervatories.

The Celestron EdgeHD Telescope advantages:

♦ wide and fully corrected field for astro photography - flat and free of coma.
♦ unrestricted visual suitability
♦ Main mirror lock - prevents the mirror from shifting
♦ Main mirror ventilation for shorter cool-down time
♦ Every HD telescope is Fastar compatible and can be turned into a f/2 Schmidt Camera.
♦ With the StarBright XLT, Celestron disposes of one of the best coatings we know. Thus offering the HD telescopes a very bright and full-contrast picture.
♦ Easy Collimation: guarantees ideal performance every time. Edge HD’s precision-machined mechanics and a spherical secondary mirror make collimation simple and accurate.

♦ Optical tube assembly
♦ 9x50 viewfinder
♦ 2" diagonal mirror
♦ 23 mm 2" ultra-wide angle eyepiece
♦ Comes with Losmandy style dovetail bar - on request, we supply a Vixen style dovetail bar (orange) instead. Please specify when ordering.
