Cloudless sky all the time I was there OMO, 8:00pm to 1:15am. But with a maximum size full Moon, a Hunter's Moon. Re-collimated the ODK and took the focuser off and adjusted the 3 element corrector lens system, by moving it IN half a turn. Put it back and re-checked the collimation with my 4mm eyepiece, which gave a 505x magnification. Took a couple of shots of star clusters and M27. The sky was hazy as well as being full of Moonlight.
I checked the filter wheel and the 17mm Baader eyepiece in the small dome and took them home to clean, they haven't been used since Peter died. I think I'll keep the 17mm EP with the ODK when cleaned.
