M-42 Trapezium Close Up
In 1989, I loaded my trusty Nikkormat FT3 with Konica 3200 ISO film, set it on the prime focus of the 31-inch f/7 Newtonian at Warren Rupp Observatory, near Mansfield, Oh. This is a two minute exposure, about the longest I could go without tracking. There is nothing like image scale! This was a wonderful film! This is almost the entire 35mm frame. The Nikkormat was great for this work since you can lock up the mirror.
