COMET 41P Taken by Mike Broussard on March 23, 2017 @ Lafayette, Louisiana, USA

Comet 41P on March 23rd, 2017, 01:18 UT. 41P was leaving the M108 and Owl Nebula area, but it still fit in my field of view, so I had another go at it. 40x180 sec @ ISO 200, TV-85 at F/5.6, Canon T3.

Also, I revamped the image from the day before this when the encounter was at its best. Ive included it for comparison purposes.

An ok aurora display. The weather was nice and the milky way was hanging beautifully over the northern horizon.

Comet 41P/Tuttle-Giacobini-Kresak poses for a Messier moment in this telescopic snapshot from March 21. In fact it shares the 1 degree wide field-of-view with two well-known entries in the 18th century comet-hunting astronomer's famous catalog. Sweeping through northern springtime skies just below the Big Dipper, the faint greenish comet was about 75 light-seconds from our fair planet. Dusty, edge-on spiral galaxy Messier 108 (bottom center) is more like 45 million light-years away. At upper right, the planetary nebula with an aging but intensely hot central star, the owlish Messier 97 is only about 12 thousand light-years distant though, still well within our own Milky Way galaxy. Named for its discoverer and re-discoverers, this faint periodic comet was first sighted in 1858 and not again until 1907 and 1951. Matching orbit calculations indicated that the same comet had been observed at widely separated times. Nearing its best apparition and closest approach to Earth in over 100 years on April 1, comet 41P orbits the Sun with a period of about 5.4 years.
