Starship Asterisk*

New Horizons is still en route to its encounter with the Kuiper Belt Object, 2014 MU69.
The bullseye in the image marks the location where 2014 MU69 will be, as viewed from the
spacecraft, shortly before the encounter.

The data was acquired to look for possible variable stars, which might be confused
with the moving object. However since it's not far off the galactic centre, there
is a lot of stuff going on in the background: black clouds, emission nebulae and a *lot*
of stars. This is a false colour image: i, g, and r-band images were combined to produce
an RGB image. Thus the green nebula slightly to the left of
the bullseye is actually glowing red, presumably H-alpha emission.

versions of the images at higher resolution, and without the bullseye, can be found at:

A Starburst Galaxy and the Integrated Flux Nebula (IFN)

This HaLRGB image portrays the turbulent starburst galaxy Messier 82 in Ursa Major with its filamentary outflows of ionized hydrogen. Seen faintly in the image is the IFN, which is illuminated by the combined flux of the stars in the Milky Way Galaxy. Total of 18 hrs exposure with a Takahashi CCA-250 f/5 astrograph; Nights of 15, 24, 28 March 2015; 12, 13 Jan 2016; 8, 9 Feb 2016 in Mayhill, NM: Paramount ME, QSI683wsg, Astrodon Gen2 filters (Ha 5 nm); (Lum 16 x 20 min; Ha 17 x 20 min; R 7 x 20 min; G 7 x 20 min; B 7 x 29 min all @ - 20 degrees C), calibrated, registered, integrated, and processed in PixInsight 1.8.5.1353 (x 64).

Taken on September 20, 2017 with a Canon 40D through a Canon 100mm f/2 lens at f/2.8 and ISO 1600. Tracked on Super Polaris EQ mount. The camera was equipped with an Astronomik CLS clip filter.

Exposures: 13 x 121 secs; 26 minutes & 13 seconds total

Taken from near Barry's Bay, Ontario, Canada.

NOTE: The meteor(?) below Saturn was on my last 121-second frame.
