Hi Johnny,
The FC-60 is 500mm at f8 or 1000mm effective on the E-1. My 1 sec
exposure in the second image was underexposed as I had to increase the
EV by 0.7 in RAW development and thus the noise came up a bit. Your
exposures were closer to being optimal. Later exposures during totality
were at 3.2 seconds at ISO 200 though all were a bit soft.
The Takahashi is extremely sharp with high resolution and would have
performed better piggybacked on the Meade with the drive running.
