Finally had some decent weather last night so despite the full moon I took the opportunity to see if my OTA internal reinforcement around the focuser had resolved the issue of the tube bending under the weight of my heavy QSI683-ws8. I also wanted to see if the coma corrector spacing was right. After fiddling around with polar alignment for quite a while I managed to capture 10 x 2 minute luminance subs on M27 before it disappeared behind the house. I think the flexure issue has gone and the coma corrector seems to be working well.
Thanks for looking
