I just put in the Files section (folder phenrotay) 2 pics that show how the 3 reference stars are positioned in the PASILL4 after having achieved a good (< 1 arcmin) polar alignment:
- PASILL4-1.jpg : Polaris approximately with a perpendicular offset from its gap: it was near the base of the engraved arrow head pointing at the gap where Polaris should be. PASILL4 rotated to have the 2 other stars are put in their gap line or close.
- PASILL4-2.jpg , when rotating the polar scope to bring Polaris in its gap,the two other stars were far from their radial lines (30 degrees or so for delta UMi).
Not 100% accurate of course, just to give an idea of the deviations.
