    That's got a 'war of the worlds' vibe. Neat! Do you know what it's meant to contain?

    Not sure except to say it could be the remains of a pulp and paper mill. There are 6 other larger, cylindrical digester tanks at the Port of Bellingham, WA, that was part of the pulp mill.

    These seem like they should be launching into space!

    Well, I got a new lens. It was on the list of lenses that are deemed good IR lenses. So, I took a chance and bought one. Plus, I wanted a wider lens.

    Tested at my favorite place. Went from f5.6 to f22. Used the 850nm filter to really stress test for hot spots. Never found a spot, even at f22!



    2022:06:12 13:36:20 : NIKON D810 : 20mm : 20mm f/2.8 AF D : 64 ISO : F8 : 1/13 sec : 5/3 EV

    Now, to go out and really use it!

    Looking good, Jon! That was my main wide angle lens from about 1994-2021. I had to retire mine as it stopped focusing. Otherwise, I'd still be using it.
