I needed two attempts. Yesterday I got up at 4 o'clock. By the time I had found the stars below in Ophiuchus, the comet was behind a tree. Today I got up at 3:40 and was started observing at 04:00 with a pair of 10x50 binoculars. And there it was, exactly where the search map said it would be. It was not easily visible, about as bright as M10/M12 and I had to look really well. I saw a big grey spot that was not exactly round, but couldn't see any tail. In the process, I also spotted Mars and Saturn, IC4665, M5 (very bright) and M10 and M12 and the asterism Sudor Opiuchi.
Comet 252P/LINEAR passing through the constellation Mensa and approaching Earth on the 18th March 2016 by Mike O'Day ( 500px.com/MikeODay ). Comet 252P/LINEAR is a near-Earth comet that was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) project in April of 2000. 252P has an orbital period of 5.3 years and passes close to the orbit of the Earth. In 2016 it passed 'very close' to Earth (in astronomical terms) on the 21st of March 2016, when, at its nearest, it was only 14 times the distance to the moon (~5.3 million kms). This image was taken three days before comet 252P/LINEAR made its closest approach when it was at a distance of about 5.9 million kms ( position as at ~16:22 Fri 18 Mar 2016 UTC as seen from the Blue Mountains above Sydney Australia ) Links: https://500px.com/MikeODay http://photo.net/photos/MikeODay Details: RA 06h 40m 38s, Dec -80 deg 18' 37" (Epoch 2016.2) Skywatcher Quattro 10" f4 Newtonian Skywatcher AZ Eq6 GT Mount Guiding: Orion Shortube 80 guidescope, Starshoot Autoguider, PHD2, (guiding on star) Baader MPCC Mark 3 Coma Corrector Hutech IDAS D1 light pollution filter Nikon D5300 (unmodified) Field of view (min) ~ 74 x 49 Stack of 185 x 7sec images @ ISO6400 Pixinsight (incl.
