The Synscan PA routine was one of the earliest iterative PA alignment process systems requiring only 2 stars and no view of SCP developed by Synta 17 years ago.
I wonder who copied the idea from them ?
I use it and it’s free
I’m sceptical about these incredibly low PA errors from various other PA alignment software systems below 0.50 arc sec using clunky bolts and hand thread torque or pressure
I get mine to just under an arc minute with Syncan ( using a zoomed in mag 2 star slightly defocused) and the guide assistant in PHD2 says 2.5 arc min
IMO PA error is a moving target each night due to atmospheric dispersion
Your thoughts on PA error values
