FOUND: Thank you Robert.
Looking for an Optec TCF-S (with RS232 serial I/F) focuser in good working condition. Also interested in adaptors to 2.7" AP R&P and SCT (C11 and Meade 12"), 2"-to-T-thread, cables, PC port converter. Please let me know what you have to offer, images will be appreciated.
CA SF Bay Area local/pick-up would be great but shipping ok.
