I added the RA/Dec values given to SkyMap's "deepsky.txt" file
and predicted ETS 6.
The first point is suspiciously perfect, though the reminder is
progressively distant from the (RA/Dec "Equ") track plot.
Switching to Stereographic projection, and Alt/Az ("Hor")
coordinates as of 21:28, the match is almost perfect.
So it appears the RA/Dec was computed from alt/az values
using siderial time of 21:28 instead of actual time.
ETS 6 should be flashing with 7 (?) second interval.
