Running Big Model

Got a couple of relatively clear hours last night, so I ran a Big Model (308 points).

Raw results indicates that both Alt and Az polar alignment are fine. Results were something like 130 arcminutes for the inner ring, 200 for the outer.

Supermodel results (after removing the one outlier):

Wow – 6.8 arcseconds.

Interesting, the polar alignment now wants a change:

************* Azimuth ************
Recommendation: Azimuth alignment is excellent. No additional adjustments are necessary.
Supporting information
MA = 30.7 arcseconds (0.5 minutes) Sigma = 1.22483 – Adjust Confidence-High.
For latitude +42° 55′ 47″, rotate the azimuth axis West 41.9 arcseconds (0.7 arcminutes).
Paramount ME: Loosen the West knob and tighten the East knob 0.3 knob tics.
Paramount MX: Loosen the East knob and tighten the West knob 0.7 knob tics.

************* Altitude ************
Recommendation: Make the following altitude adjustment…
Supporting information
ME = 65.7 arcseconds (1.1 arcminutes) Sigma = 5.35898 – Adjust Confidence-High
‘Ideal ME’ = -64 arcseconds (the refracted pole).
ME adjustment to get to above ‘Ideal ME’: 130 arcseconds (2.2 arcminutes).
The polar axis should be raised 130 arcseconds (2.2 arcminutes).
Paramount ME: Raise the polar axis 1.1 knob tics.
Paramount MX: Raise the polar axis 2.0 altitude tics.
