cool down

[shanmac]

Could someone please advise me?

When taking my skymax 127 from inside my house to the outside garden to cool down before viewing, should I take the cover of the mirror and leave the eyepiece holder empty so as to let air curculate?

i would say no to both, just make sure you give it plenty of time especially if you are imaging! couple of hours should be enough

I put my scope in the garage for an hour or two before observing on cool nights. Don't expose the optics to air and dust if you don't have to, though! And make sure you cap everything securely before you come back in - that can prevent your optics fogging up when you come back inside - and save you a lot of headache from water spots!

Hope that helps,
