In response to Alexs' post, and I may be right off track, is there benefit in pre-heating/warming your EP so as to alleviate the difference which will then allow for quicker stabilization. Has this been tried?
Fans on Newtonians, is this considered a mandatory item that if not fitted is something that is worth fitting? If this is the case what is the suggested method?
Cheers,

With fans, their main purpose is to assist with cooling the mirror prior to use. I never normally run mine while in use simply because I never bothered setting up a system to power it while moving the scope around. If dewing does turn into an issue with your primary then a fan can possibly help.
Some people have made up heated eyepiece boxes, I made one up but in the end went with a rack that held all my eyepieces with heater straps on them and then had them prewarmed prior to placing in in the focuser.
