The two pictures below, taken at an interval of 24 hours, show the star field around Pluto : hence the planet is the only dot that moved in the meantime... Can you spot it by yourself, above the centre of the field? If you do, you are repeating the procedure that led to its discovery in 1930...

West is up □ Comet 6P/ d'Arrest, discovered in 1851, is a short period body (some 6.5 years), so it can be witnessed several times in a lifetime, although some of the approaches are not favourable to observations. On November, 24th, we succeeded to capture it, in Piscis Austrinus, at a respectable magnitude of 10.2, an easy target under clear skies.
The view below shows the brighter nucleus, slightly shifted (it moved some 15 arcsec. during the exposure time), all embedded in a subtle greenish coma.

On this view we can appreciate the two main spiral arms of the galaxy, with the supernova standing to the right of the upper arm (see the marks on the small icon at left).

Canon 60D at prime focus of SCT Meade 403mm reduced at f/6, total exposure 15 minutes, ISO 3200 ; East is up □ On November, 19th, at dawn, there was a partial eclipse of the Moon visible in almost all Americas, reaching up to 97% of the lunar disk covered, hence giving a nice display of contrasted colours.
Eclipse begins, the eastern limb already appears darkened :
