Tom Pickett: The Elephant's Trunk

19054955_1389177324463708_6238371311812216973_oHi Everyone.. I hope you are having a good day...:-)
Here is my first image processed by my new rebuild refurbished computer.
This is the Elephant's Trunk Nebula.
While my computer was down I focused a lot of time and attention on this object with my Canon 300mm FD F2.8 SSC Fluorite lens and my 2 Canon modified cameras.
This is over 15hr’s of 150 images stacked at ISO 400 at 6 minutes each plus just under 4 hr of 39 images shot with the Optolong 7nm H-Alpha filter with both images merged in Photoshop using the HA data as a second channel along with the RGB.
I hope all of you like it... :-) The details are below..
Have a good day and clear skies everyone. :-)
The Elephant's Trunk nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the west of IC 1396A. The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.
The Elephant's Trunk nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.
The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the centre outward lead to very high compression in the Elephant's Trunk nebula. This pressure has triggered the current generation of Protostars.
