Sure, there's a whole article about it on my website.
https://joe-cali.com/ Go to the bottom of the home page and look for the article on
APPS. APPS stands for
Artificial Projected Pole Star. It's simple, quick and cost me $30 to build 4 years ago. I can usually do a precise align in about 4mins and then don't need to do any dec corrections in 3 min subs at 1300mm focal length. I've been using it since 2018 and it's never failed me. The only problems I have affect any method of polar alignment, tripod legs sometimes settling into soft ground during the night. I leave the laser in place turned off. Then it only takes a couple of mins to re-check and re-align the polar alignment during the night. This only occurs when the ground is saturated and wet.
