The benefits at a glance:

  • pin-sharp optics with an above average image quality
  • 94% reflection at primary and secondary mirror for a brighter, high contrast image
  • large-sized 88mm secondary mirror for good illumination
  • Main mirror and secondary mirror version of metal - fully adjustable
  • MONORAIL focuser with 1: 10-micron reduction
  • ideal for commercial coma correctors for astrophotography
  • two Losmand- dovetails opposite: for mounting on the Mount and accessories such as a guide tube

The Carbon tube with stainless steel and aluminum compounds:

The tube combines the advantages of Carbontubus, as regards the temperature stability, with the stiffness of a Full tube. A refocusing when temperature changes is not necessary. The build quality is excellent, the connection parts are made of aluminum in precise CNC manufacturing.
