We tuned the AC sensor on the power board. @lucboucher explained the need for a realistic current draw during the calibration process, so we used our PSU and a 10 Ohm power resistor to pull about 1 A to set the threshold voltage on the comparator. This works, albeit we need to test that when we turn off mains power, POCS reports the problem and shuts down the unit.
We are on the roof of Steward Observatory this week. I believe we succeeded in polar aligning our mount last night in spite of some cloud coverage. The process was pretty straightforward since @nem told us about the finder scope - it also helps that we’re not in LA. Here are some setup pictures:
SETTING UP THE UNIT
GOOD THING WE DON’T NEED TO LOOK SOUTH
And the polar alignment iteration we stopped on:
CAM 0 (the one used to solve for the celestial poles)
ROTATION OF CAM 0
ROTATION OF CAM 1
Assuming this polar alignment is satisfactory and, if necessary, we just have to tweak camera focus or other lens parameters, the next step is to set up an observatory in POCS and schedule an observation. We want to track a known transit much like PAN012 did.
We don’t have internet access on the rooftop as we initially predicted. This may change, but for now we’re just going to have to save all of our data onto an external hard drive and upload them to the Google cloud storage later.
