While testing some new polar alignment code this evening, I came across an interesting screenshot I wanted to share.
I positioned the telescope to point just North of the Equator, and just West of the Meridian (and I'm in the Northern Hemisphere).
I ran polar alignment with two 30-degree slews going West. I had intentionally messed up my polar alignment by about 1/2 degree.
Looking at the log, spot of the 3rd PAA image is azimuth 253.934 altitude 23.5716.
What I wanted to point out, is that the correction triangle is telling the user to use the altitude knob to move the star along the yellow line seemingly
AWAY from the ultimate target. When the user reaches the end of the yellow line, then adjusting the azimuth knob would bring the star along the green line to the target. It turns out that there are spots in the sky where azimuth and altitude corrections at the pole map to surprising directions like this. This is the reason I originally came up with the idea of introducing a correction triangle.
In fact, I followed the directions given, and the resulting correction worked fine. I verified this by re-checking polar alignment at the pole.
