Photonis INTENS and L3 Filmless Image Intensifiers

Recorded in black and white for the purpose of eliminating any visual bias that would arise from phosphor differences. This Photonis INTENS uses P22 phosphor while the L3 Filmless uses P43. I specifically ordered a P22 phosphor INTENS so that I could take advantage of a longer decay phosphor. Though P22 has no effect on measured SNR, it can increase the perceived SNR the viewer is presented with. —————————— Targets: Ring Nebula Dumbbell Nebula
