I have some accessories I purchased for my C8 Hyperstar from Buckeye Stargazer that only recently arrived and I no longer need. They are brand new, never been used.
Basically selling these at cost price. Save yourself the GST and postage costs from the US.
All accessories listed here are for the Celestron C8 Faster/Hyperstar model.
Firstly I have a Tri-Bahtinov Mask. The mask seperates into 3 sections so you can mount and remove the mask without removing your camera. Very handy for both focusing as well as confirming collimation.
