Gathered some data over the past two New Moon cycles from a remote location with very dark skies. This was the first time I've used ACP from this location and it was completely successful.

NGC4631 7x600s LRGB with 253mm RCOS @ f/9 with ST-10XME

.62 arc sec/pixel - 2276 mm of focal length.

using the PIR, ACP put the guidestar on the chip *every* time and except for some minor configuration problems on my part the guiding went very well.

Kudo's Bob ! .... This was, and is, great fun.

Comments welcomed.
