Cooler Box
I build the cooler box some time ago.
Found it cumbersome and painful to insert it in the focuser.
Lately I tried building a box with the camera at the rear instead of on the side
But gave it away. Too fiddly.
I went back to the original box, improved the insulation and the access to the camera and was able to get the temp down to 10 - 13 degrees below ambient with the camera in the box.
Am now quite happy with the box despite still being a bit of a nuisance, but prepared to put up with it. Now for some clear nights.
