Description

In spite of a nearby waxing moon and owning no filters for my Newtonian, I tried to capture M57 in Lyra as the constellation was rising. The oval and distorted star shapes are still a headache, perhaps a result of inaccurate collimation or distance between coma corrector and DSLR. Anyway, when PHD2 throws a "star did not move enough" error during calibration, connecting the ST4 cable helps.
