I've decided to ditch the GSO Crayford focuser on the rc8 due to unreliable autofocus issues.

TS show two suitable rack and pinion units, TSFOCR25 and TSFOCR25S.
The 25 does 6kg and teflon bearings, the 25S does 4kg and ball bearings.

Apart from that, they seem amost identical, but the 25S is 40 euros more. Perhaps a case of "yer gets what yer pays for".

Any advice?

Can't help other than say I bought the 25S, when I had my RC8. Hands down fantastic "upgrade".
A bonus for me was that I already had a reducer, and a flattener, both were bought for my TS90mm CF apo, and they both fitted (screwed straight on) to the 25S.

Thanks for the info, Gary. I will email TS asking their inputs on both versions. The difference in payloads is a bit puzzling, one would expect the higher payload to be the better build, not the lower cost model.
