Very nice Paul! Glad to hear your back surgery was a success!

Years ago one of the astronomy magazines (?) used this title to describe
"recent" data recovery from archived B&W observatory plates. That article
came to mind after I found some of my lost 1997 color negatives of comet
Hale-Bopp. These showed little color and no ion tail in the commercial
print on my wall. Coincidentally, my doctor told me to avoid heavy
lifting after my recent successful back surgery, and that's offered
wonderful opportunities to do light work. Since 1997 I had acquired an
Epson large format negative scanner. The film was 6 x 7 cm PPF-2 hypered
film. Two of the processed images show a nice blue ion tail and can be
seen at:

I'll check the exposure data later, but the camera was my original 8 inch
f/3.6 hyperbolic astrograph (1996) with hypered Kodak PPF-2 6x7 cm color
negative roll film on a vacuum back. Exposures were about 5 minutes.
Corner-corner images span about 4 degrees (see vignetting in one of the
images) .
