GETTING TO KNOW YOUR TELESCOPE

The parts of the telescope and their functions are identified and described below.

1  Front Cover. - black anodized mashined Aluminum with
push-pull spring loaded latches. It protects the optics and holds
the dew shield during transportation. 
2  Retractable Sliding Dew Shield. This feature makes the OTA
shorter for handling and transportation. The open end of the
shield is rounded to improve aerodynamics of the front end of
telescope. Rounded edge creates less turbulence compared to
straight cut baffles.
3  Shield flange. It holds the shield with four 4-40 screws.
4  Tube assembly. The tube interior is coated with a special
light absorbent coating and has 4 sharp edged baffles, which
block internal reflections. 
5  OTA Focusing Mounting Flange.
6  Focuser.

See following Instructions written by Detlef

Schmidt (Starlight Instruments Inc.).
The focuser’s tube is coated inside with the same special coat-
ing as the tube assembly.
7  Plug. It is a small part that keeps the focuser end closed.
