While waiting for the cloud to clear I decided to tilt the RH200 so it pointed at the deck. I then loosened both Zero Tilt Adapters sequentially and made sure everything was fully home before retightening the bolts. This would eliminate any small misalignment in the image train due to assembling in the horizontal position.
After the cloud finally went away I took a series of exposures in HA. Each exposure differed by 200 steps of the Atlas focuser or about 20 micron of travel..
Here is the single 4 minute exposure where focus was best. No flat or dark correction.

Managed to get some quick data. This is 10x4 min with 3nm NII of the SMC processed upsized at x1.6 in size. 5MB

Note this was collected with a near full Moon and the SMC fairly low in a light polluted sky.
It is obvious something was not fully inserted home. I may not need to touch the back plate adjustment at all.
The guiding still needs a bit of tweaking.

Tomorrow the weather report is favourable. We live in hope.
