I did use an orange filter (taped onto the front of the shutter, cell mounted behind the shutter). The single cells are anti-apochromatic (if that is a word!LOL!) Blue light is focused in a much different plane than the other wavelengths. Eliminate much of the blue light and one eliminates much of the problem (and gain darker skies, if so desired)
It is a contact print -- I suppose using a single cell on a 4x5 and trying to enlarge to 16x20 might show excessive softness...but I did not notice any softening in the platinum/palladium print (which are not the sharpest way to reproduce an image to begin with).
I used the 28" cell to photograph a lunar eclipse (5x7 back on the 2D), no filter used and the cell behind the shutter. An exposure every 10 minutes. On the 5th exposure, the cold night air (just outside Yosa-mighty) froze up the shutter and it did not close, the shutter stayed open for ten minutes -- I discovered it trying to start the next exposure. So, a few images of the moon coming out of totality, then a long white streak! Your Packard shutter could probably handle it. I'll put on a filter just to protect my shutter from the cold and damp next time!
Minimilist is a valid approach. In a universe of infinite possibilities, any 'restrictions' placed upon oneself by limiting one's gear will still result in an infinite number of possible images!
