Here is a screen capture from SkyTools 4 Imaging, for Uranus and the 5 brighter moons as viewed from Brisbane tonight, 24th Oct 2019 at approx. 11:55pm.
The separation between Miranda and Uranus is approx. 9 arc secs which is approaching maximum.
I'll give it another go to see if I can position Miranda away from my spider's diffraction spikes.
Cheers
