I am surprised with this shot, I didn’t think the K3 was that good at high iso. What did you do for post processing

I agree with Lowell, this is an excellent result at such high ISO. Also, a cute pic!
Thanks! I have found that indoors high iso on the K3 often turns to mud but outdoors it can be ok. Playing around in Lightroom I came to the conclusion that the biggest problem with K3 sensor is that the noise pattern is just right to be super enhanced by sharpening algorithms so I aggressively apply a sharpening mask. Other than that I don't feel I did anything special in post. Here are the Lightroom settings I applied.

WB: As Shot Temp 6650 Tint +2
Exposure: -0.88
Contrast: +33
Shadows: +25
Whites: +5
Clarity: +14
Sharpening Amount: 65
Sharpening Radius: 1.0
Sharpening Detail: 25
Sharpening Masking: 80
Noise Reduction Luminance: 16
Noise Reduction Detail: 50
Noise Reduction Contrast: 0
Noise Reduction Color: 50
Remove Chromatic Aberration: On
Post-Crop Vignette: -33 (to take the emphasis away from the bright sky on the right)

I managed to get the Astrotracer calibration a little better and got this shot of the Orion Nebula. K1ii with a DA* 300. I stacked 17 shots in Sequator. Each was about 5 seconds at ISO 800.

Northern Flicker
Pentax K3 with DA* 300mm F4

Not as critically sharp as I hoped but I am new to this. Couldn't get a clear shot with no branches in the way and this guy didn't wait around for me to get a better position.
