I even made SerrurierTruss from rectangular 25mm Al tubing, but saved only ~1.5kg.. so I decided to abandon this approach, and go for bigger mount.
All I've managed to do is add weight to mine!
- Replaced original Meade rings with Parallax
- Replaced original Vixen dovetails with Losmandy
- Added a doubling plate behind the focuser to avoid flex
- Replaced QHY8 with QSI683ws8

I originally planned to replace the mirror cell with something more sturdy to help hold collimation however tighter springs seems to have worked ok with the original cell.

I had also contemplated Moonlite's new Nitecrawler rotating focuser but it is quite heavy so haven't progressed that plan (yet).

Guess I like tinkering!
