I sold the scope I used this on so I no longer need this. It was made for a Meade ETX or Orion Apex/StarMax but I used it on a 80mm ShortTube and a FS70 too. Will fit tubes with a 4.1" OD or slightly smaller with felt or something similar. Glass is like new, housing shows a few marks from use. Sells new for $60 plus shipping, I'll sell this one for $40 shipped. Paypal (add 3%) or Money orders.
