I bought both 10” and 8” Klaus Helmerich Carbon fibre OTA’s ( tube only ) through Sidereal Trading in Melbourne and retrofitted my own GSO focusers , spider and mirrors etc…
Ended up with good quality light weight imaging Newts . I use f5 , too many issues with f4 tube newts , f5 is faster enough for DSO and Planetary in my experiences
Sidereal Trading are now making their own carbon fibre 10” and 12” newts in f4 and f5 as well
Give Paul or Diego a call
Cheers
Martin
