• 9.25" (235mm) f/10 EdgeHD optical tube fully corrects for coma and field curvature, delivering a truly flat field
• Native f/10 focal ratio can achieve the image scale necessary to capture the smallest of deep sky objects-or image at f/7 with optional focal reducer and f/2 with third-party lens assembly
• Premium patented StarBright XLT optical coatings provide maximum light transmission
• Compact and portable Advanced VX mount offers a maximum instrument capacity of 30 lb with the same rigidity as our larger mounts and minimal flexure
• Every feature an astroimager wants: PEC, an autoguider port, the ability to image across the meridian, and more.
• Dual saddle plate is compatible with narrow CG-5 dovetails and wider CGE dovetail.
• Accessories included: 23mm eyepiece - 2", 1.25" Star Diagonal, and a 6x30 finderscope

• 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 2 focal ratios: native f/10 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

• Massive 44-pound payload capacity support guiders, filters, cameras, and more
• Equatorial GoTo mount with built-in USB PC control
• Belt drives provide minimal backlash and significantly reduced periodic error while remaining whisper quiet
• Stepper motors have no internal gear box, further reducing backlash
• SNAP port eliminates the need for remote shutter release cable
• Autoguide port compatible with most of today’s best autoguiders
• Sturdy carry handle to ensure safe and easy set-up

• An incredibly simple and intuitive astrophography computer
• Control your mount, camera, and more wirelessly
• Automatically stack and process images for extraordinary deep sky or planetary images

• Anti-Light Pollution: The Antlia Quad Band filter is an effective solution for reducing light pollution, as it cuts out most of the orange-yellow lights from 589nm and part of blue lights from LEDs
• Possible to shoot over 95% of deep sky objects
• Unique spectral design offers more possibilities for astrophotography
• High transmittance of the main emission lines Ha/SII/OIII/H-Beta in the visible region, enhances the astrophotography's high SNR and contrast;
• Near-infrared (NIR) region transmittance
• Passing near infrared region is for shooting deep sky objects that cannot be shot with other filters without NIR transmission
• The broad bandpass designed to cope with faster optics up to the f/2 focal ratio.
• Good color balance
• It is easier to achieve color balance by adding the short-wavelength transmission
• Superior optical reliability reduces post image processing
• Basic Substrate: Optical, Single / Non-glued substrate
• Surface Quality: S/D (scratch/dig)= 60/40 (Refer to MIL-O-13830)
• Transmitted Wavefront: Lambda/4 or better.
• Parallelism: less than 30 arcsec
• Warranty: 3-years against delamination
