Hoping to observer and image Friday night.

Hopefully clouds don't ruin the night. I am just wondering how much time do I need to give my scope to acclimate to the outside temperatures? I believe the temp will be around 30 degrees Fahrenheit.

cool down time really depends on how much glass/mirror you will be cooling. that said, I rarely wait if observing as the deep sky stuff can handle a low mag. be aware that the moon is going to be close to full this week-end so I'd stick to moon for imaging.
