One thing I observed afterwards is the fact that Sky Safari can not be made use of in conjunction with PHD2. Sky Safari reviews an error when guiding is in development. evidently only one application may be used to manage the mount’s motions in a time.
. in the course of the 1977 occultation, astronomers envisioned the star’s light to disappear because the World moved across it.
