How reliable is the temp reported by SGP?
I use a 1600MM and cool the cam to -20C when imaging.
I tested different temperatures from 5C to -20C and I don’t see much of a difference in the noise level in the subs making me doubt of the cooling.
Can I trust SGP for reorting the right values?
Is there another way to test the cooling of the camera than to rely on SGP reported numbers?
thanks
