    Your issue now is high ISO noise? try to overexpose slightly and the noise should be reduced, since it will form a smaller component of the entire signal.
    ACtually it is always good to "expose to the right" and then pull it back down in PP. that way you maximize details in shadows, and at the same time minimize noise.

    Bro, this is a 100% of a pic i took few days ago. 100s exposure at ISO 50. So these are noise or "stuck pixels" resulting from overheating of sensor?

    Those are commonly known as 'color noise', totally removable..

    When you do NR in PP, you are always offered 2 kinds of NR, Luminance noise, and color noise. Doing Color noise NR will get rid of this.

    I think we need to set aside another outing date to talk about shooing to avoid noise... "Exposing to the right"

    I think that will be very valuable and necessary for most of us...
