The static DoF (Skyrim blur) is as customizable as the fog values (except for the coloring of it) and I have actually turned those values off for the time being in my weather mod, except in one weather SkyrimCloudyRE or rather I turned it off in the imagespace of the weathers except for that one. This will be added back again once I have reached a good looking value for it, depending on the weather. So that it can be turned off by the RemoveBlur command if a user don't like to have that blur.
EDIT:
Here is the WeatherTundra outside Solitude. The regional weather WeatherTundra stretches from Whiterun all the way to Solitude, check the Weather map in my signature for more area coverage.
Vanilla with ENB Activated, vanilla sun texture

ELE with ENB Activated, vanilla sun texture

ELE with ENB Activated, ELE sun texture

I have not added a noise filter as the vanilla texture had to prevent banding, so it will be a clear sun. Instead I worked out the banding issue by adjusting the gradient brightness of the sun glow around the "Sun disc" circle that makes up the sun. Also to note is that the size of the Sun is the same as vanilla but the glow is less intense so it won't blow out the sun but still keep those long nice sun rays

Vanilla settings (auto generated enbseries.ini settings) where used here except for these things;
Every effect except for DoF was activated.
