Off Axis Guider and Reducer for SCT's

Off axis guider for SCT's that have a 2" visual back plus a 0.5x Reducer lens/ Tele-compressor. The OAG has an adapter ring the other end that screws in to standard Nikon, Canon and Sony Nex, T rings.

These were sold to me by a reputable IIS member. I no longer have a C8 and they have sat in my accessory case for too long so I need to let them go as I don't think I'll ever use them now.

I can not work out how they both attach together. You may need an additional adapter to attach them together and more spacer rings to reach focus for both camera and guide camera hence the low price.

I can not find any info online for these or any that look similar but they do come with some old instructions from the film photography days. They are in good condition and will get someone going with off axis guiding or the reducer lens to reduce their image scale for astrophotography. The reducer will make your f/10 SCT into a fast f/5 SCT and reduce your focal length by half as well as your exposure time.

Please don't ask me specifics as I have no idea and all the info I know about them are on the old instruction sheet.
