The perfect adapter to connect your Canon Mirrorless camera to your RASA 8

Enhance your 8” Rowe-Ackermann Schmidt Astrograph (RASA) by blocking light pollution, improving image contrast, and darkening the sky background.
This filter selectively blocks wavelengths of light from sources of light pollution, such as streetlights, not broad regions of the spectrum.
Does not block wavelengths associated with emission nebulae, keeping your nebula images bright and detailed.
Fits into the 8” RASA’s integrated filter mount, maintaining peak optical performance.
Optically flat surfaces free of defects, constructed of Schott glass with anti-reflection coatings.

The Celestron Focus Motor for SCT and EdgeHD enables electronic focusing using a computer or Celestron computerized mount hand controller for remote/hands-free observing.

Self-powering: When connected to a Celestron computerized mount, the mount provides the power. When connected directly to a computer, USB provides the power.

Compatible with a wide variety of Celestron Schmidt-Cassegrain, EdgeHD, and Rowe-Ackermann Schmidt Astrograph optical tubes.

Motor controls include multiple speed rates, automatic GoTo indexed focuser position, and focuser backlash compensation.

Focuser Utility software for Windows provides a simple user interface. Also compatible with Celestron PWI.

Enables autofocusing with a camera and third-party software via ASCOM.

Indexed focus position allows the motor to automatically return to a previous focus position and prevents the focus motor from reaching the end of telescope’s mechanical focus travel.

If you have an 11" Celestron RASA telescope, and you want to attach the Celestron Electric Focuser #94155  you will need this retrofit kit to make it happen.

• 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 – six precision sealed ball bearings virtually eliminate 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.
• 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.
• The CGX, with its 55 lb. load capacity, is Celestron’s most innovative, state-of-the art, computerized equatorial mount to date, and provides a very sturdy and rigid platform for the fully-loaded RASA 8.
• The drive system utilizes low cog DC Servo motors with integrated optical encoders, belt and pulley motor connection, spring-loaded steel worm gears supported by precision sealed bearings, and brass worm wheels for smooth, accurate slewing and tracking performance with little backlash.
• Fully remote imaging capable, with optical limit switches, home sensors, through-mount cabling, and hard stops.
• Included Celestron PWI software allows direct computer control via USB 2.0 connection.
• Proven NexStar+ computerized telescope control technology supports functions to address imagers’ needs, such as All-Star Polar Alignment, Permanent Periodic Error Correction (PPEC), and adjustable tracking through meridian.

700 Maksutov-Cassegrain telescope with f/15 focal ratio provides high contrast views of the planets and lunar landscapes, perfect for serious planetary imagers and visual observers.

Celestron’s premium StarBright XLT coatings ensure maximum light transmission.
