In restoring a Mak scope, I have had to totally remove the paint. This has left a rather attractive bare aluminium OTA, and I was thinking ... would it help in cooling a Mak faster if it was left bare?
I seem to recall some doing similar things to OPEN tubes like Newts, but insulating Maks, so would I actually be better served painting the tube?
I like it shiny
(plus no paint 'n polish blues
)
