Actually the outer case seems to have excellent heat conductivity. Even at delta T -15 degree under ambient, I am just measuring about under 1 *C in disperancy from the front and the back( even smaller if I keep the delta T lower) And since the etalon does not directly screwed into the outer case I think it wont introduce too much heat gradient into the etalon.
Any suggestion for a DIY Quark active cooler?

Re: Any suggestion for a DIY Quark active cooler?
Thanks Christian,
I still wanna do some testing with tilting as a 2 pronged approach to the tuning and see what works best.

Thanks Mark,
Hope it works. If it does I'll make a 3d printed case for better mounting mechanism

Re: Any suggestion for a DIY Quark active cooler?
Hi
When RodAstro took the retaining screw out of the joint between the red bit and the black barlow/combo that the joint is not screwed up tight.
There are a series of holes for the screw so its unlikely to be screwed up tight.
So the pressure of the tie downs will be tilting the joint I presume.
The screw is a imperial torq security one I think being USA.
Cheers. Andrew.

Re: Any suggestion for a DIY Quark active cooler?
Thanks Andy, I worried the same thing too. But i tried to flex the joint between the black telecentric barlow and the red outer case but it seems solid to me, no flexing. And when I make the radiator I already take this joint into account, the tie down and the radiator actually both applying pressure to the black telecentric (the radiator extends about 5mm and seats partly on the telecentric barlow) , the tie-down on the 1.25 inches eyepiece drawer is fixed lightly.AndiesHandyHandies wrote: ↑Fri May 21, 2021 7:58 am Hi

Re: Any suggestion for a DIY Quark active cooler?
Okay so the cooler works very well. Brings the temperature down about -12*C.

Re: Any suggestion for a DIY Quark active cooler?
Maybe I should patent it. "An apparatus for cooling optical filter". Sounds good )

You should sell the patent to DayStar ;-)
