I decided to do a rotation movie of an iconic view from Voyager 2 of Neptune on August 17, 1989. It is in Voyager OGB-o-rama, interpolated to 10 minutes per second from three or four frames of each record. I copied Ian Regan's brilliant idea of injecting the spacecraft movement back into the video, and took it one step further by putting the reseaus back in. I geometrically corrected a raw dark current calibration image using the GEOMA program in VICAR but didn't erase the reseaus or clean or calibrate it in any way, keyed out the dark current, and laid the reseau image over my video. There is very little subjectivity here - you see more or less exactly what the narrow angle camera saw during this sequence, with only geometric and radiometric calibration and removal of digital artifacts. Personally, I love the reseaus - you know you're looking at images taken with an old, analog spacecraft camera when you see them.
