Imaging In Freezing Temperatures

[Andyb90]

Hi Everyone,

Looks like I may get a clear spell tonight, but the temperature will be 0 to -1 degrees.

Will my 80mm ED refractor, HEQ5 and finder guider (with QHY5-ii) be okay in that temperature range or is there anything else

I should/need to do to protect the equipment.

I don't have a permanent setup so the scope and mount will be out in the back garden with my laptop.

I've got a dew heater and tapes for the scope and finder guider.

Any advice on this would be appreciated.

Andy.

It will be fine - this type of gear is designed to be used in sub-zero conditions. Your laptop could usefully be covered with a simple cardboard box (open to the front) but provided it's powered up it will not come to any harm.
