There are 3 ways to do polar alignment, let's Rank them by accurate level:
- Most accurate: Polar Scope
- Mid accurate: Star Pointer
- Less Accurate: Emergency Hole
A, MSM-SiFo Polar Alignment with Star Pointer.
Turn on the star pointer, aim the beam to Polaris, try to align the laser beam with the Polaris. Once aligned, then you are ready to shoot.
B, MSM-SiFo Polar Alignment with Polar Scope.
Firstly, with the help of the star pointer you've almost aligned with the Polaris, then install the Polar scope on to the mount. (The same mount with Star Pointer). With the help of the engraving marks on the scope lens, you can do an accurate alignment with the Polaris.
Polar Scope is necessary for the long focal lens.
How to use the engraving mark on the Polar Scope?
C. Polar Alignment without Star Pointer /Polar Scope (Emergency Help Hole).
Thanks to Alyn Wallace's idea.
Use this hole for draft polar alignment once you forget your star pointer or Polar Scope home.
