Big K, did you notice any evidence of the dust storm in Chryse? My views were terrible until I got the fan running, then everything became tack-sharp. I would advise anyone using a scope with passive mirror cooling, or not breaking-up boundary layer in front of the mirror with a fan, to allow several hours of cool- down time before expecting the best views.
My view was too fuzzy in a 6" DOBm, but good point on the mirror cool down. I'll try pre-cooling the mirror. If the weather breaks, I'm trying for higher altitude, maybe in Big Cottonwood, and ending the evening with a drive out to SPOC. - Canopus56(Kurt) __________________________________ Yahoo!
