I was using PHD2 for guiding since long. I had doubt if PRiSM v10 can do better sub pixel guiding with 50 mm guide scope (I modified 9x50 finder scope to a guide scope with help of 48mm adapter). Earlier, I preferred 80 mm short tube refractor for guiding but it was increasing mount load...

I just changed guiding parameter into PRiSM v10 and results are with you..
