Congrats Adam! Those are really nice images
As a PHD user who has still to get this whole thing going, I have a question for you: do you remember what durations PHD used when guiding?
Down the bottom in the status bar when guiding, it says something like
E dur=xxxx dist=yyyy
Where xxxx is the last guide pulse duration in ms (I believe) and yyyy is the distance in pixels of how far the guide star has moved.
For me PHD is using dur=1000, so 1 second guide pulses, but my guide star keeps drifting steadily away anyway. I think this is due to atrocious polar alignment (I have problem doing a drift alignment due to where I setup tonight - basically no western or eastern horizon views).
Cheers and congrats again,
Steve
