In trying to set up a dual side by side system I have come up against the enemy, differential flexure. This is some form of often miniscule movement between the two scopes that leads to elongated stars. Until now i have been using the Takahashi Clamshells. It's been suggested that these could be causing the small movements and so I've moved to scope rings.
Unable to easily find 95mm scope rings, I have bought and fitted Prima Luce rings and a Losmandy dovetail. An excellent and well made product I am hopeful that this will resolve my flexure issues.

Finally after weeks......a clear night.
The moon is MASSIVE and the conditions with high humidity are far from ideal, but as this is a 2 pane mosaic I knew that I'd get away with it..... 9x1800s in each pane, more data needed but it's a start.
