Vixen PF-L II Polar Alignment Scope – Easy & Accurate Polar Alignment for Equatorial Mounts & Star Trackers (ES35532)

Accurate Polar Alignment for AP, SX, AXJ, and AXD Mounts

The PF-L II Polar Alignment Scope inserts into your mount's polar axis and uses a 3-star alignment method to get you to within 3 arc minutes of true polar alignment — precise enough for confident long-exposure astrophotography. Align three reference stars (Polaris, δ UMi, and 51 Cep in the northern hemisphere) with their positions on the illuminated reticle, and you're done. The reticle includes Big Dipper and Cassiopeia constellation patterns as guides, so no hour-angle calculations are needed in the dark.

Compatible with AP, SX, AXJ, and AXD series mounts, as well as the POLARIE star tracker.
