Hi Geoff
Thanks! The apparent size of Pluto is around 0.1” and I think the Mewlon can resolve around 0.6” (Dawes limit) so what we are seeing is not the disc of Pluto, but the effects of smearing due to the Earth’s atmosphere along with errors in tracking.
I think this is why the stars, which are effectively pin points of light, also appear as discs?
Cheers
