Comet 41P/Tuttle–Giacobini–Kresák

Closest Approach of Comet 41P/Tuttle–Giacobini–Kresák at Magnitude 8.6 in the Constellation of Draco.

Comet 41P is still visible in Binoculars from a dark location, it is heading for Perihelion on the 12th of April.

On April 1st – 2nd, the comet passed by Earth at a distance of about 13 million miles (0.14 astronomical units), or 55 times the distance from Earth to the moon; An unusually closer approach for this Jupiter-family comet. Comets are frozen balls of Ice, Gas, & Dust that start to sublimate when heated by the sunlight as they approach the inner solar system.
The green color is the Comet P41 Spewing C2 Diatomic Carbon which glows green when lit by the sun in the Vacuum of Space!

Here is my shot of Comet 41P as it passed within 13 arc minutes of 4.58 Magnitude Star 10 Draconis, & 4.7 Magnitude Double Star WDS HJ 3342 (WDS = Washington Double star Catalog)

Taken with my Homemade 16 inch Diameter Newtonian Telescope and a Canon 6D DSLR,
20 frames x 30 second exposures (10 minutes) stacked in Deep Sky Stacker, comet Mode.
Captured from 08:26 U.T. to 08:46 U.T. at my Observatories at JBSPO in Yellow Springs, Ohio

Comet Jacques C/2014 E2 Putting on a Show!!!!

Here is my shot of Comet Jacques from last night 08-28-2014 from 05:19 U.T. to 05:42 U.T. Still very bright about 7th mag, looks good in Binoculars too! The Comet is up all night for us Northern observers.

It is currently moving through the Constellation Cassiopeia in to Cepheus and is Visible rising high in the North all night long now.

Comet Jacques C/2014 E2

08-28-2014 from 05:19 U.T. to 05:42 U.T. Taken at my Observatories & MVAS Dark Sky site In Yellow Springs, Ohio www.mvas.org

20 x 1 minute subs, unmodified Canon 6D, ISO 3200, Prime Focus of my Homebuilt 16″ Diameter Newt. Scope. I’m working on the movie, but that will come later. The faint tail shows up much better in a long exposure Stack, after stretching the 16 bit data in Maxim DL. I used StarStax in Comet mode to make this 20 minute exposure stack.
