H
So we are clear, are you telling me 2arc/secs P/P 0.45RMS guiding with say 2-4 arc/sec seeing is 1. Shocking atypical 2.Very bad atypical or 3.Just bad atypical ?.
Even at 3000mm FL I found that guiding to be more than acceptable image wise, and was more than happy with it on my G11.
Are you sure your not talking about a flat line in perfect still dark conditions in the field?.
I think youll find 99% of astroimagers would be extatic with 0.45 RMS error H, not sure how or why you could dissagree frankly.
