Thank you Lester, Jeff & Troy
I’ve just completed the animation; it’s not perfect as I just couldn’t seem to normalise the background between frames so there is a little “flashing” between frames.
I’ve also included a mosaic showing the position of Neptune. The Neptune component (lower slot) was a 3 min exposure and you can see the huge bloom. In the (upper) 20 minute frame, at the bottom edge, you can just see a glow which indicated the position of Neptune, well below the border.
I noted that the text book magnitude of Nereid was around 19.6 mag., but decided to have a go as the NASA/JPL Horizons ephemeris indicated 18.72, just within reach of the C9.25.
