GSO seems to have a cooling fan and seems to be made from glass. I have asked the shop about the lens material on skywatcher and if it has cooling fan on it. Also if it has knurled collimation knob.
If Skywatcher has cooling fan and knurled collimation knob and uses pyrex mirror should I go with skywatcher?

Some people say:
The main advantage of the (Skywatchers') Pyrex mirror is that besides cooling down quicker it tracks temperature changes during the night better than a plate glass mirror. No need for a fan.
Others have thought a SW mirror coating is better quality and lasts longer.
Others say that the GSO has so many other better options that it is better quality (eg dual speed crayford focuser, included cooling fan.)
Another thing, if you can get one with a right angle finder, thats a big difference too.
As you can see, its a tough decision.
One you have to make yourself.
Because people value different features differently.
