Yeah guys I worked with film also ,400 and 800 iso mainly. Just short moon shots using my 8" at prime focus and longer hand guided using reticle in 8" and piggy backed pentax K1. Mount was AOS samson with drive corrector. Still using same mount for visual. 3-4yrs ago wife found a roll of techpan 2415 in the freezer that I forgot about that I must have bought 30yrs ago
