APPENDIX
Slowly remove the polar axis scope from the Polarie and replace
the cap and camera mounting block.
The position of the north celestial pole moves gradually each year
due to precession. According to this, the position of Polaris shifts
every year as shown in the figure. Place Polaris at a position on the
alignment scale in the reticle to match the year of your observation,
between 2005 and 2025.
