cooler box
I have the GEOPTIK cooler which I acquired from Teleskop in Germany I think.
It is heavy, and the things I don't like about are...
it's fiddly to undo the box and change the mode from M to B etc when using a software focus using live view- all the cold escapes!
the screws are in the front so you have to put your hand between the box and the scope to undo them.
The thermometer it came with was dodgy.
SO.. I upgraded the thermometer, and once sealed in (blu tac around the lens hole and cable hole) I got a drop from 12'c to -4.8'c within about forty minutes.
it does create condensation so you need dessicant.
With judicious removal of a tad of foam it also accomodates the 60Da.
I think with upgraded quick release clamps and the blu tac it will be a bonus for the camera.
Yo do need a sturdy focuser as along with the camera it is quite hefty.
Cheers
Graham
