90D pushed images look clean (no banding)
11

I case someone was wondering what they can expect after pushing their long exposure images by 5 stops, I am happy to report that the images exhibit no banding.

30 seconds @ ISO 100 +5 stops from raw in LR Classic with no corrections/NR:

Normal exposure (reduced size, for brightness reference only):

The only thing of note in my quick test was a small streak of what looks like "hot" pixels. This is with long exposure NR on (dark frame subtraction). There was typically only one and it was in a different place each time and had a different orientation:

Here it is on one of the sweaters in the closet (not in the image above):

Here's a couple on different pictures of the closet wall:

So I guess if you're shooting stars at 30-sec exposures, you'll have a few additional streaks in your images. But they will be easy to find, since their direction/orientation will be different from rest of the stars.
