(These are test shots of the configuration - please don't judge their photographic quality, which is zero! The better one of the four was the brick corner I published above!)
No, no vignetting on these print scans... maybe I cropped it out. I do remember having that issue. I have to go down to the darkroom and fish out the negs...
Okay, it is back to bench for me. Thanks for your help, Rafa.
To the readers, we got these Metrogons years ago for about $35 each, including center filter - an irresistible challenge. They were so reasonable that I didn't even blink when I dropped one down a full flight of cement steps.True.
...and I have a couple more, still unmounted, that I bought some time later from the surplus place you connected me with! The assembled one is a different mount design. The two loose elements are very promising as experimental pieces.
Putting your feet to the fire, buddy. So, how did you manage a shutter other than a Packard?
.
Not sure what you ask... but it would not be you if you didn't...
The shutter came from the big auction site, it has iris and shutter and is in reasonably accurate working order. The Metrogon glass is approximately 41mm in diameter, which is the diameter of the threads of the old shutter. Clamping it against the glass, carefully, was not a great risk, as the Metrogon is uncoated. I believe that the reason for vignetting was that the shutter was held too far away from the glass by the depth of the threaded ring, and it "throttled the opening down" a bit... Can't think of what else to say... did I respond to the question?

Feet starting to smell bad and to feel pretty hot... Jac? I'd like to get up and go to the bathroom! Was that what you were asking?
Cool info for 8x10 enthusiasts! Thank you for this thread
