Hello Hello Astromarters!
I have a telescope dust cover manufactured for an Orion SkyQuest XT4.5. I imagine it would work for any 4.5" dob also. This is only a dust cover, and is meant for indoor use. There is padding in the tube fabric to protect against light collisions. There is a drawstring around sewn into the fabric to place underneath the base.
Sells for $45 new from Orion and is backordered till 3/3/04. Buy yours now for $30 shipped CONUS via priority mail. Fedex and UPS extra. Will take MO or Paypal (+3%).
