Re: Telescope Focuser And Temperature Acclimationm
I drink beer! It relaxes me so I don't worry about the speed of optical cooling so much.What do you do to quicken the temperature acclimation of your telescope?
Just sayin',

Re: Telescope Focuser And Temperature Acclimationm
Lately with the temps in the teens to low 20's F (-10 to 0C), it takes about 45 minutes, especially for the long
I did discover one thing the other night when it was 15F (-10C). I took out my orange C80, which originally had the objective cover inside the aluminum dew shield. This was awkward, so I replaced it with one I made from a margarine container lid, some plastic and good ol' duct tape. Much easier, and it's a snug fit.
I let the scope sit for almost an hour. I went out, and saw I hadn't taken the cover off the dewshield. I went to do that, and for the life of me, it wouldn't budge! Seems the plastic contracts more/faster than aluminum in the cold...
Took the scope inside, was able to get it off after almost 15 minutes, took the scope back outside, let it cool down again...!! Lesson learned
Yup, time and beer; good call on both counts. And remove all plastic covers beforehand
All the best,
