Moving to ONAG so selling the OAG. It was bought from second hand back in 2021. It is missing some extension barrels, buy I never needed them for my Celestron EdgeHD 11, my countless adapter and those that come with my cameras plus the filter drawer is all I ever needed. Please see the manual picture with the red crosses indicating the missing ones. What I include, and I did always use is the large STC adapter for ONG, usually cost around £30. I will post anywhere in GB for NI will have to pay the difference in postage, buy very happy to post there too. Postage included.
