push-pull spring loaded latches. It protects the optics and holds
the dew shield during transportation.

shield is rounded to improve aerodynamics of the front end of
telescope. Rounded edge creates less turbulence compared to
straight cut baffles.

ube assembly. The tube interior is coated with a special
light absorbent coating and has 4 sharp edged baffles, which
