3” focuser

Recommended Posts

I could do with replacing the 3” focuser on my 102 refractor. Without paying silly money my options seem to be the Revelation from Telescope House

or the TS-optics focuser

Anyone with any experience of these or opinions would be appreciated.

Hi Doug,

 

If its of interest, i have this focuser sitting redundant in the garage :

I've been meaning to advertise it on ABS but have not got round to it.

I believe it has an M95 thread (on its own) and has an adapter to fit a 116mm tube. Other sized adapters for it  can be purchased i'm sure.

Its a good quality rack and pinion and has 90mm drawtube travel iirc.

 

PM me if you want to meet up and check it out etc.

Cheers, Rob.
