I have for sale a BRAND-NEW-IN-THE-BOX JMI Motofocus system for the C8 which was never used (see photo). The installation instructions also include information for the Ultima, PowerStar and Classic. Although I am not 100% sure, I think (?) it may also be suitable for other SCT's above 8" as the focus knob seems to be the same.
I am asking $115.00 plus $10.00 for insured air mail shipping. PayPal only please (I will cover the commision fees if you are using a cash balance).
If you have any questions, please feel free to send email requesting additional information.
