Every thing was fine, I had nice images of Jupiter and Saturn, up till two
days ago. Left the C-11(black OTA. it's been hot, here in East-Bay) mounted
in my back yard, last night not done any observation, but tonight I tried,
but the collimation is way off. Stars fanning all one way, can't even make
out Saturn's shape, it's a blob. Mount was under an umbrella sort of in the
shade, but can the heat do that?

Thanks, Julius
