Thanks again E.L. I did as you suggested and lightened the words and logo. Definitely improve the shot. One thing I didn't mention the shot is 4 stacked images for greater focus. I missed the right knob, one more focus shot for that area would have got it. Now this area is all I see. Another thing I should have done was to tether the camera to see the full image better on computer screen. I thought about tethering but thought I had it.
I don't find the slightly soft focus on the right knob distracting at all, rather I think it improves the image.
