Fits like a charm on my ‘80s Celestron Orange OTA.
This mount fit my older Celestron c8 perfectly, allowing me to use my new mount. Really good quality and solid.
Exact fit for an older celestron carbon fiber 8" tube. No issues and came with what was needed.
Overall was good but OAG prism was found a bit damaged.
Quality of the product is excellent. New screw was supplied for the single front mounting but had to reuse the two original small screws for the rear mounting. Dont know if they were supposed to be supplied? Shipping of nearly $30 to Aus is a bit excessive for an $80 product. Packaging was good, probably a bit excessive, may account for the volume base shipping cost.
