This is a cropped picture through a 500mm Genesis 4" Refractor at F/5 covering about 3.7' x 2.4'. This was a 15 minute exposure taken on Hypered PPF 400, 35mm film, 30 miles NNE of Mojave California, (4 miles north of Red Rock State Park) on 18Feb97 at 13:10 U.T. The negative was developed normally in C-41 and scanned on Kodak Photo-CD. To get the most amount of detail from the dust & ion portions of the comet's tail(s) I processed the blue and red channels through an unsharp mask and shifted the highlighted color region with the hue/saturation functions in photoshop 3.0.4. The image was then color balanced to show a neutral black backround. Note the delicate tendrills along the beginning portion of the ion tail. Has anybody seen these features visually?
