ASI224 Hot Pixels?

johnp

I seem to be getting more hot pixels lately then I used to. Please look at the attached images and tell me if this amount of hot pixels is in the "normal" range. Is there a way to get rid of them?

Dark frames stacked in Sharpcap

10 x 5 seconds gain 250

you need use dark to calibrate it

They show up on my dark frames generally in the same location. How will this help if stacked? It seems like I'm getting a lot more then I use too. Is my sensor defective?

Sam@ZWO

they are hot pixels

this is normal

usually cooling can help to reduce the hot pixels

that's why we need cooled cameras

software can calibrate by checking the hot pixels in your dark frame

.Hi
My asi224 sensor has some hot pixels that show up bright and colorful at medium gain and low exposure and don't disappear after stacking when shooting planets.
How to get rid of them?
How and with what program can the sensor be reset by hardware to return to the initial state?

Please provide any software and hardware solutions that can help.
Thanks
