3. The new ultra duty focuser with a new camera rotator will carry a 5 kg. load to accommodate the new large chip CCD cameras with an 88mm image circle with a 9.5° field . It includes the new Takahashi fine focuser.
  

4. A new f/3.6 reducer is a great option for wide field imaging producing a 6.5° field.
  

5. The redesigned modified four element double ED Petzval optics have been optimized for imaging and will produce outstanding visual images.
  

6. Color correction has been extended to 1000nm to provide non bloated imaged stars.
