gso back focuser on combination of rc8 and ts flat2
Teleskop Service has a good customer service. Information about backfocus is also usually written on the flattener page.
I have the GSO RC8".
For the KAF8300-Chip there is no need to take a correktor, because the field of a RC is flat!
For APS-C or bigger you can use the 1:1 RC-flattener "TSRCFlat2" - Distance 109mm.
For reducing the focal length the CCDT67-Reducer is fine - Distance 85mm +/- 5mm.
By the way: for kollimating the RC the best and easiest way is, to use a Cheshire Collimating Eyepiece (TS-No: 0 TSCH)
