Did anyone have tested the Orion DSLR camera cooler???
It seems very interesting. And I'm I wrong in thinking that this would be an easyer way of dealing with dark frames since we can control the temperature ??? If I want to take all my pictures at -20 degree , iso 800 ,for a while I could use the same master dark ???
Tell me what you think about it .
Thank you guys !

I was looking at that as well. I know when its 20deg F outside, my T3i chip runs 25-30 deg warmer, roughly 54deg.

Not sure it would yield much better results and is kind of pricey. I do see where many have made their own by tearing down a 12V cooler from say wal mart. seems like a lot work too.

Seems if the chip isnt cooled by a 'cold finger' we still have the camera housing insulating the chip which keeps it warm.

My 2 pennies, curious to see what folks say. would love to have darks at way smaller temp range somehow, not to mention a cooler camera to lower noice to begin with :)

Does this camera cool to a specific temperature or does it cool to something like 40 degrees below ambient.

If it cools by 40 degrees below ambient it is good. But your chip temperature would still be dependent on ambient, and therefore would have to be careful matching (or scaling) the dark frames.

And this says nothing about whether it is "worth" it. And whether cooling around the camera will get your chip cooled. And whether it is good to add that much weight to your focuser, and all the other things that will be mentioned here.

I went and look in the instruction manual and there is no control of the temperature...I was disapointed ! I thought that it had a thermostat and that we could set a temperature and it would stay around that setting but no.
So because of that I dout i will buy it. And you have a point there Alex ,it is heavy at 2.5 lbs .
Thanks man !

I think it would help ,but to what extend ? 2.5 lbs is heavy for my kit ,and $400 is heavy on my wallet !
If only we could control to a desired temperature and it would keep it there ,but no ! No control ,not buying !
Thanks DrDispatch !

I have the Orion cooler and love it. It drops my cameras temp by 30-40 degrees F. I used to image with my sensor temp around 40-45 degrees C in the summer, but with the cooler my sensor never goes about 25-30 C. Its a bit heavy on your Dec axis but other than that its a good buy.

Anything capable of reducing the sensor temperature (without causing internal dewing) would help. From all the research I did on this device, it doesn't seem worth it. The outside of the camera body can be cooled by a few degrees, but the sensor itself is unlikely to get below maybe 8 or 9 degrees centigrade, which is pretty close to what you can achieve by blowing cool air over the outside of the body during a freezing night anyway.

And as others have noted - it reports the current camera body temperature digitally, but offers no thermostatic control over it. I'd pass.

How on Earth (or maybe it was somewhere else) did you manage to get your sensor at 45 degrees F in a Texas summer, without some sort of cooling? I am totally impressed.

Power requirements?? I just plug mine into the AC power strip I use. Not too bad of a requirement.

I wonder how much can it cost for the shipping ???
Because it is exactly the same as the Orion one ,only the price is way better ! Even with the shipping ,it will be a better deal...
Thanks Jeff !
