Polar Alignment Tool 2 - PAT2

Here’s the latest development in my eternal quest to obtain a good, rough polar alignment in the daylight at unfamiliar observing sites (e.g. astro camps). The FOV of my Polar Alignment Scope is approx 3° so this altitude technique should get me with ±1° of the SCP.

Basically, it is a 360° protractor glued and screwed to a piece of 20mm x 20mm aluminium angle, with a plumb bob weight attached to a piece of orange line to help read the scale.

Cheers

Dennis
