Astrophotography Accessories

• Allows the user to replace the FeatherTouch MicroFocuser on the RASA 11 with a traditional focus knob for compatibility with the Celestron Focus Motor
• When combined with the Focus Motor, this kit enables you to focus the RASA 11 using a computer or Celestron hand control for remote/hands-free astroimaging

• The EdgeHD .7x Focal Reducer Lens makes your EdgeHD 9.25" one full F-Stop faster than f/10, reducing your exposure time by half to capture the same brightness of object
• 4-element lens design
• Maintains similar flat-field performance as native EdgeHD optical design
• Increases field of view by 43% to better capture wide field images
• Threads directly onto the 3.25" threads of the EdgeHD which reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders
• Maintains the identical back focus when used at f/10 and provides generous back focus to accommodate additional accessories and wide variety of cameras
• Allows use of existing EdgeHD T-Adapters with or without the Reducer Lens

This accessory allows to connect a ball head adaptor on top of the star adventurer mount. It features a 3/8″ thread.
