Apertura Dust Cap for 10" Dobsonian or Newtonian
Apertura 10" Newtonian Dust Cover
This dust cover comes standard on Apertura and GSO 10" Newtonian telescopes. We are offering it here just in case you need a replacement. It also makes a good frame should you wish to build a stop-down mask or, if you acquire your own mylar or other safe solar film, your own solar filter for your 10" Newtonian.
