Quote:thanks for the help. It will give me something to do tonight. I imagine that each time I change a parameter in the settings, I should recalibrate. Is this the case? I have not changed a thing, other than what I have done to my imaging camera. I have always guided with the st80/ssag combo, and this scope/mount combo.mike

Quote:I was imaging (or trying too) the horsehead nebula - pretty close to the ecliptic. The night was cloudless, but seeing was really bad. My exposure for the guide scope was 3.5 seconds. The star was pretty bright, but not the brightest in the frame - should I use the brightest star? I was afraid that it would take up too many pixels and mess up guiding.
