I always try to get my PA under 20 Arc seconds. I have found that Sharpcap gives me good results. I did need to turn on the atmosphere refraction option. It says that the atmosphere is refracting the light 1.4 minutes of arc. Do you use software for your PA?
No worries about the reducer!

I use the Synscan PA routine in the handcontroller, been using it since day one about 5 years
I just use my old Canon 600D in the newt , connect to BYEOS ( use PA alignment window reticle target ) switch on live view , zoom in 5x and select 2 brighter stars east of the south meridian above 30 degrees and below 65 degrees, one star is the PA alignment Star and the other is the second alignment Star , 2 or 3 iterations to centre PA Star by tweaking Az and Alt and 10 minutes later I’m under an arc minute. Take a 60 sec sub on that PA Star , zoom in , check that’s it’s nice and round ( my focal length is 1000mm ) and we’re done !!
I can use any 2 stars in the sky ( don’t need a view of SCP ) but closer to the south meridian the more accurate and quicker the process becomes
It’s as good as a Pole Master
