Taken with the double stack PST mod at 2000mm fl with the DMK31, this picture shows double stacking does show some promise, however these images from saturday are all slightly in the wings of the Ha line. The DS PST mod is complicated to setup, and at the moment i'm still working out all the many variables and their innumerable combinations. The problem I do have is a spell of consistent and continuous sunshine to test out properly. Still, with each outing i'm getting a better understanding of how it works and the optimum way to set this combination up.
