Dob cooling part IV
Some of you may remember I had cut a hole in the side of my OTA to remove the boundary layer a few months back. I had since cover it with cardboard and a rubber band once i got my peltier system up and running.
Well I took it off and now am peltier cooling extremely well.
I can keep the mirror at 1 degree below ambient as it is falling.
Very nice!
