GETTING TO KNOW YOUR TELESCOPE
PARTS AND THEIR FUNCTIONS ARE IDENTIFIED AND DESCRIBED BELOW:
1 - Front Cover. Made of anodized black aluminum. It has TEC logo in the center.
2 - Retractable Sliding Baffle. This feature makes the OTA shorter for handling and transportation.
Open end of the baffle is rounded to improve aerodynamics of the front end of telescope. Rounded
edge creates less turbulence compared to straight cut baffles
3 - Baffle flange. It holds the baffle with four 2-56 Button Head Screws
4 - Tube assembly (OTA). The tube interior is coated with special light absorbent coating and has two
sharp edge diaphragms, which block internal reflections.
