Single 2mn frame with Pluto, red filter.

Pluto was visible on the evening sky, pretty low on the Western horizon. While waiting on my main target for the night to go up (Asteroid Dembowska for an 8 hours photometry run), I did a few 2mn frames on Pluto, also investigating a possible problem of movement/sag of the primary mirror in its cell (resulting in defocusing and decollimation) when pointing at very low elevation. Anyways, below is a raw frame (plate solved) with Pluto at Magnitude 14.4.

Zoom on Pluto.
