Hardware Issues

A list of issues encountered:

• The OTA of my telescope is not mounted parallel to the fork arms. When I put it in polar home position and rotate the telescope back and forth in RA, I will never find position (by adjusting the declination) where the stars move around a center.
  
• The optical axis is not aligned with the mechanical axis of my optics. When I use the f/3.3 reducer or the f/6.3 reducer with a big spacer, the vignetting is off center. Coma is visible in one corner when I use the f/3.3 reducer.
  

• Internal reflection caused by the visual back.
  
• Telescope didn't fit in the JMI case.
  
• The handy microfocuser mounting thumbscrews that were included with the JMI case ruined the original visual back and many of my images.
