No idea how it does but it does it!! In the actually camera controls it goes down to -40!!
I still have my K3 and K20d IR. I am hoping to get a K1 next year.

This was not taken by a Pentax, but....
Instead this was taken with a cooled Deep Space Object Dedicated Camera, a ZWO ASI183MC Pro. It has a 1in 4/3 sensor at 20mp and 2.4um pixel size. I traded in a couple of Pentax bodies I haven't used in months, and an unused EQ mount.... because for what they are, they are not cheap!
But they are cooled.... really cooled... the sensor can be cooled down to -20°. This makes them extraordinarily sensitive, as well as reducing noise. The advantage of this is (apart from the fore mentioned ones), unlike a DSLR, in which you have to allow the sensor to cool (usually half the time of the exposure) between shots. With this one, you don't. That means you can shoot half as many light frames again.
So.... as you will probably figure out from now on the vast majority of images I'll show you guys, will be taken with this camera!
Enough waffle now....

UPDATE
Sorry for taking my time! Been a bit busy....
BT Web Protect is off...
Cleared all date and caches...
No effect... the website is still doing all the stuff I mentioned in my previous posts.

Number 6 is the standout one here, for me that is!

You cannot beat some nice weather outdoor!
Especially with a camera.... i like all of these, especially the doorway one in the other post.
If you don't mind me asking.... did you use a polariser?

Well here they finally are.... Same location as the others I posted!
Last night I left the DIRTY word camera's at home, and grabbed my camera bag with all my Pentax kit in it.
Kit used - K3, Sigma EX DC HSM 10-20mm f3.5, iOptron SkyTracker Pro, a tripod, ballast, a lens heater, and big powerbank powering them all!
These are composites. The Milkway image was shot with the camera pointing pretty much straight up! I couldn't really shoot towards the horizon because of light pollution. Next I took several foreground images. The Milkway image is a stack of 80 images, then stretched in Siril and PP'd in PS and TopazAI DeNoise/Sharpen. Image 3 is the most realistic one. The other two have a bit of artistic interpretation!
Oh by the way.... the red nebula at the top of the images, that's the North American Nebula, and the star just down to the right is Deneb!

Cool and Bugger!!!
Was hoping you might know someone down there!! I've been looking for a place to do DSO Photography that way... It's probably the part of the Peak to do it.

Here are a few more utilising full frame, dirty word camera.... I sooooooo want a K1. Hopefully next year! I think my days shooting APC maybe over.... Altho I hope not, as I love my K3!
But....
Until then I will have to use dirty word full frame one!
Here they are, also which do you prefer A or B?
A
B
And finally, same sky shot composited in ti a different foreground.

From what I can understand of the principle, it's temperature difference that counts so the temperature you dial in might be the difference with respect to ambient rather than the actual temperature of the sensor - perhaps worth checking.
Steve
If the ambient temp is 25, the the camera will cool it by 35 degrees to get it to -10. If the cameras max temp (for cooling purposes) is say 30. Then it will only be able to cool it to -5. Mine is cable as of 45....
That's a WOW image!!!!
