Thanks Glen,

Yes the clouds started to limit my viewing as well which is why I quit when I did.

If you have the scope out you can easily 'see' the atmospheric conditions by selecting a star and defocus (outward usually) to see the effects of the atmo on your view - if It's wobbles all over the circle your seeing will be atmo limited, if it is rock solid and you can see the collimation rings clearly then you have good seeing, relatively speaking.
This actually brings up another question I had, and it still relates to viewing, but is more a collimation question. :-)

When I de-focus either one of my scopes, the image I get is no where near textbook. It has always been a full light circle, with multi-colored scintering inside. On the newt I can see the spider as well. I have concluded that this was due to atmospheric reasons, mostly heat related. Am I correct in the understanding that this is probably more a combinative effect of the atmosphere in general, including light pollution, and that I would never see the collimation circles until I have a much better sky to look through?
