Hi Greg,
Thank you for your input. Very interesting. Can you explain what PA with a T point is ? I use the PA sequence in my ASIair. It tends to get me within a couple of dozen arc seconds. I find that the Dec is pretty good at under 0.5 RMS which I would imagine suggests that the PA is “ good “ relatively speaking. I am interested is what the T point is though. To be honest I’m not expecting miracles from testing the different filters, I just find it interesting. I image in Bortle 8 skies and my seeing is never “ good “ so I’m working with a pretty bad canvas to start with.
Cheers
Ryan
