Thanks Mick - still trying to work out Orbitron! Some good links & interesting background there. The 2 sats you mention are probably a bit too far west to be the one in the second image I posted.
I got the first one again tonight (almost due NE from my location). Image attached, a stack of only 8 untracked exposures this time. The shot has a cast of thousands, possibly the most cluttered image ever posted on IIS
.
My apologies!
Cheers -
