EDGEHD 14" OPTICAL TUBE ASSEMBLY (CGE DOVETAIL)
-
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
|
|

|
|
-
11-inch f/2.2 optical design with rare-earth glass for images free of false color, coma, and field curvature
-
43.3mm optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging sensors, while the usable field extends even further to 52 mm for larger format sensors.
-
Custom engineered linear brass focuser bearing reduces image shift, while dual-speed 10:1 FeatherTouch Micro Focus Knob provides the most precise focusing
-
Quiet, high-output 12V MagLev fan reduces cooldown time and blocks dust
-
Common camera adapters (T-thread and M48) included for easy attachment to popular CCD and DSLR cameras
|

|
-
Flat field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
-
Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras.
-
NEW Ultra-Stable Focus System – precision linear ball bearing virtually eliminates image shift.
-
Integrated air cooling system –12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust.
-
Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
-
CGE dovetail mounting rail.
-
Performs over a wider spectral range than most telescopes, from 390-800 nm, so more of the light passing through the astrograph is in sharp focus.
