Everything is in great condition; the primary mirror and secondary mirror are in very good condition, the carbon fibre tube and anodised aluminium parts are unmarked, it’s fitted with the original focuser which can handle the heaviest cameras, three focuser backs included for various purposes.
The mirror is coated with Orion’s optional Hilux enhanced aluminium coating, which lasts 25 + years and reflects up to 97% of the light it receives, read about it here-

These scopes are advanced astrographs and at f6.8, they are reasonably fast for astrophotography, with a reducer they become even faster at f4.5; I have been successfully using an Astrophysics CCD Telecompressor (CCDT67) (not included) which brings the focal length down to f4.5. The Explore Scientific 3" Field Flattener .7x Focal Reducer - FFFR507X-00 also works with these scopes giving a focal length of f4.76.
The ODK16 can also be used visually.
Comes with - - Fan Cable
- Front Cap
- 3” Focuser
- 3 x Focuser Backs
- Collimating tools and instructions specific to the ODK16.
- Ronchi Collimating Eyepiece
PLEASE NOTE: CAMERA, GUIDE SCOPES, COMPUTER OCAL CAMERA ETC AS SHOWN IN SOME OF THE PHOTOS ARE NOT INCLUDED.
Reason for selling, too many big scopes and I am getting too old to keep swapping them on the mount.
