I used PHD2 tonight for the first time. The drift align tool is amazing. Even with the learning curve, it took less than 10 minutes to go from an error of 3 degrees down to 3 arc minutes. Sure beats looking at a crosshair reticle for 45 minutes while swatting mosquitos.
I was a little shocked ant humiliated looking at the error curve displayed in arc seconds rather than pixels as in PHD1. I guess this gives me something to work at improving, although I was happy with the guiding results I was getting with PHD1.
