These images are not from the original negatives (they must have been lost during three of our moves since the 1980s) but from 5x7 color prints which I enlarged and processed myself. One of my better astrophotographs is of M42 Orion Nebula but unfortunately the only remaining print I have is 11x14 and I don't have a flat-bed scanner large enough to convert it to a digital file. I suppose I could re-photograph it with one of my Canon DSLRs and post it some day if I can ever get around to doing that.
After originally scanning these astrophotos with a CanoScan 9000F flatbed about four years ago, I recently took an opportunity to digitally tweak them in the ArcSoft PhotoStudio 6.0 photo-processing suite which was originally packaged with the Canon scanner. Unfortunately, there's not a lot one can do with an image lifted from a color print that's probably about 35 years old!
I hope you enjoy looking at my old-school astrophotography knowing that it still doesn't represent the state-of-the-art of what was possible with hypered film and higher-end equipment. I don't have the original data specs for the individual pictures, so I'll do my best to recollect general exposure times and the lenses used to capture each photograph.
Equipment:
Olympus OM2N 35mm SLR camera
Kodacolor 400 non-hypered safety film (ASA 400 which is roughly equivalent to ISO 400)
Negatives processed in C-41 and printed in my darkroom on Kodacolor color print paper using a Durst M601 Dichroic Enlarger with color head attachment.
Most of the photos have been cropped to one degree or another to overcome some edge flaws and slight vignetting which would occur from time-to-time.
All exposure times are approximate because I don't have my notes any more and I'm working from an old man's memory! Heh! Don't scrutinize too hard or the flaws become more apparent. The best shot of the North American Nebula I got was on the first frame of a 36 exposure roll so the Mexico end of the image is a bit washed out being the first frame and too near to the exposed leader of that roll when originally loaded into the camera. My normal practice was to click past the first two frames once the film cassette was loaded in the camera and then the first exposed frame would theoretically be clean.
