[LewisM]

All night I have struggled with PHD, and only ONCE did it guide for the full 5 minute sub. The rest of the time it drifted out constantly. Turn PHD off and the mount kept tracking PERFECTLY, 3 minute unguided subs without difficulty. Tried PHD again, and off it goes AGAIN.

So, in desperation I fired up MaxIM, and set the autoguider up. After doing the star select, calibration and voila, I am tracking impeccably, 5 minute subs without trailing, pushed to 10 minutes with nice stars.

I have no idea what is going on in PHD (almost like the hemisphere is reversed or something, as it keeps pushing RA the wrong way!), but this has been an ongoing problem since upgrading it 2 revisions ago. For now, I will keep using Maxim, which is dead easy and you can zoom on your target star easily.

I LOVED PHD previously, but now it just frustrates all poop out of me.
