Mirror Temps?

[Mikezoom]

Hi All,

I have read how before observing it is reccomended to let your scope's mirror reach equilibrium but does this also work with Refracters and Binnos?

Many thanks,

Mike. B.

Refractors still require a cool down, although they do not require as much time. The air space will usually cool down quicker than a mirror. Bino's probably don't require much time at all.

Kool, thanks for that Paul. :)

my 10" reflector needs at least 1/2 hr to 1hr after the outside temp stablizies to get within 1 degree. Now the putside temp does not always stablize, so it gets fiddly when imaging down here in tassie

i am using ice packs to speed this up and making a mini "Bird" peltier cooler.
