Messier 1 – Crab Nebula

This deep sky object is called the Crab Nebula. It is a supernova remnant that was the first Messier Object – M1. It is located in the Constellation Taurus and is a Milky Way Galaxy resident that is about 6500 light years away. Messier was tired of finding objects like this when he was searching for Comets, so he devised a list of deplorables like this in order to avoid them in the future. I managed to tease out some interesting detail in M1 by using three extremely narrow band filters (Oxygen, Hydrogen and Nitrogen) and assigning them to colors that would enhance the detail in the image. One advantage of narrow band filters is that they filter out moon glow which was almost at it’s peak during these imaging sessions. The 25 stacked exposures totaled about 12.5 hours through a six inch refractor at f8 with a 1200mm focal length. More details are available at my Astrobin site. http://astrob.in/287183/0/

The Spaghetti Nebula – Simeis 147

From Wikipedia:

Simeis 147, also known as the Spaghetti Nebula, SNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Auriga and Taurus. Discovered in 1952 at the Crimean Astrophysical Observatory using a 25-inch Schmidt-Cassegrain telescope, it is difficult to observe due to its extremely low brightness.

The nebulous area is fairly large with an almost spherical shell and filamentary structure.  The remnant has an apparent diameter of approximately 3 degrees, an estimated distance of approximately 3000 (±350) light-years, and an age of approximately 40,000 years.

It is believed that after its stellar explosion a rapidly spinning neutron star known as pulsar PSR J0538+2817 was left behind in the nebula core, emitting a strong radio signal.

Tadpoles – Happy New Year

These are the Tadpoles of IC-410.  They seem appropriate for the New Year when we are celebrating a fresh start or a new beginning.  This emission nebula lies about 12000 light years away, and the Tadpoles are about 10 light years long.  This is a stacked composite of 17 half hour h-alpha exposures taken through my 5 inch Astro-Physics Starfire refractor with a .75 focal reducer.
