I came across this pdf from Bresser from last year that discusses a 12" variant offered, as well as the standard 10" etc:
Has anyone heard about this?
The major difference (other than the size) seems to be with the OTA
10": "Tube made of metal with adjustable brackets and altitude wheels made of aluminium.."
12": "GRP tube with adjustable tube clamp and aluminum altitude bearings.."
Would be happy to hear more about this 12" Dob! How does GRP material compare to metal?
