Okay, but the graininess across the entire field really needs to be removed. It looks like film developed in hot developer.

Almost all of your images have this kind of graininess. We need to figure out at which stage it appears. First, we should look at the raw files and camera settings, to see if it's already present in the raw data. Then, we should examine the post-processing. Could you provide a link to one or two raw files and the stacked image after calibration (bias, darks, flats, and frame registration)? You can send it in a private message.
