Digital cameras do often have problems with long exposures. The pixelation you refer to is generally referred to as “noise”. The noise can be intensified from the heat generated by the sensor during long exposures. It’s even worse at high ISO settings. I have a few things going in my favor to keep the noise low. 1 - Canon is touted to be one of the best cameras when it comes to low noise although Nikon has may have caught them in their most recent offerings. 2 - I usually shoot at ISO 100. The fact that the first shot above is at 400 is unusual for me. 3 - I have a piece of software called “Neat Image” that does a great job of noise reduction in post processing. Another popular one is called “Noise Ninja”
