Hi Brendan,
The original design goal was to place Sigma Octans somewhere in the FOV of the Tak EM200 Polar Alignment ‘Scope (PAS) during daylight on the 1st day at astro camps, whilst waiting for nightfall to then get it spot on using the illuminated reticule.
The 4 stars that make the Octans Trapezium just fit inside the FOV of the Tak PAS, which is around 4 degrees.
Here is the link to the original post which describes the
Altitude and Azimuth set up jigs.
Cheers
Dennis
