Hello Friend,

  Many years ago Schmidt Cassegrain optical tubes were hand ground by optical technicians. It was a slow and labourious process to do this  and it required the constant attention of the optician.

Optical quality could be hit and miss depending on who was at the grinding apparatus monitoring the primary mirrors and corrector plates.

Even the optical coating chambers varied in terms of the quality of the coating applied.  Finding skilled optical masters became
more difficult as they either went into business for themselves (ie Cave Optical) or worked for the military, ,which was more
lucrative.

Yeah. You get paid more for killing the enemy.

A sobering thought, folks.

However, now with sophisticated CNC manufacturing equipment Meade Instruments is able to produce consistently high quality
Advanced Coma Free optics, in greater volume and that is why right now you can purchase one of these optical tubes, ready to mount
on your existing eq mount. at very reasonable prices.

Savings of up to $3500 on the largest Optical tube assemblies.
