Bit of an update:
- Work and excessively cloudy conditions meant I've only really been out observing for the past week or so.
- I built a wedge, CNC machined up some aluminium pieces and built a reasonable facsimile of the Celestron mass produced unit.
- However it's showed up the limitations in the single arm alt-az mount. Aligning using EQ South allows for accurate goto, but the tracking is woeful. The mount in straight alt-az mode tracks better.
- The whole assembly is less stable with the wedge fitted, even a slight whisp of wind shakes the OT enough to show up even in short exposure photos.
Looks like I'm shopping for a HEQ5 or better mount and tripod, hell I'm even considering a pier in concrete.
