Dust cap for 150mm Newtonian and RC telescopes

This plastic dust cap is suitable for:

• GSO Newtonians with 6" apertures
• GSO RC telescopes with 6" apertures
• Similar devices by Teleskop-Service, Meade and Omegon

Tube attachment: The protective cap is made from plastic. The cap has bars on the side for a better hold. In order to achieve an optimal fit on the tube, you can gently grind down the bars on the side with a file. However, bear in mind that the cap will always fit a little tighter in winter than in spring.
