This time of the year, when the indoor temperature is a lot warmer than the outdoor temperature, I put my scope (SCT which requires a "longer" cool down time than some other types), in the garage as soon as I get home, then a couple of hours later, I set it up outside, figuring cool down time is significantly reduced. -Ken- PJ Savolainen wrote: > Hi all > > Any knowledge of which type/brand of telescopes have shortest cooldown time? > > Regards > Pena
