I tried beta 345 last night under less than ideal skies with haze and imaging low in the north east on M 82. Every thing worked well. I had one star lost message and recovery started . I checked PHD2 and the star was not lost and the guider was still tracking thought poorly. I was impatient so I clicked on try now and every thing worked again. I just love the new auto focus and both manual and program auto focus work well with no errors. I had a problem with SGP shutting down with my Atik camera and filter wheel but this seams to have been resolved now. So congratulations this is now becoming very stable platform for me.
