Thanks Asher. I've taken a little heat lately on other forums such that I blabber too much about the lens and the picture would not stand alone without the ecclectic lens info so I chose not to say anything much about that.
But since you asked :~'))
The lens is a very simple achromatic meniscus from about 1880 called a
Waterbury. They were included with a cheap everyman's Model T of a camera that
Scovill marketed in the 1885 era. The lens is factory throttled to about f12 or so with a soldered disc. Knowing that some of the best soft lenses on earth are AM's I wanted to remove the disc and use it wide open, which I did here. It surprised me being sharper that way than I expected. The glow from abberation is there but it's almost microscopic. I doubt sharpening anywhere would improve it, wrong tool for that job.
Here is a much larger file though if anyone would like to fiddle with it. I welcome that.
