Orion Nebula

... The Orion Nebula Christmas Night ...
The famous Orion Nebula, Messier 42, is such a beautiful telescopic object. I took this picture Christmas night in my backyard using the big 11" Celestron telescope with the 0.7X reducer lens to reduce the focal ratio to f/7 which widens out the field-of-view. This is only a 7 minute exposure. My goal in this image was to NOT blow-out the core so that I could see some of the individual stars.

This is a large gaseous region where new stars are being born and located about 1,344 light years away. It is just a blur to the naked eye but looking through even a small telescope exposes its colorful nebulosity. But still, it takes several seconds to several minutes of camera exposure to really capture the beautiful colors associated with it. The colorful reds, blues, and greens are illuminations and reflections from the radiation given off by these new stars.
This nebulae is located high overhead around 1 am in early December.

Other Pictures of Orion from my backyard
March 4, 2018
My first picture with my new 80 mm ED80T CF Apochromatic Refractor in the backyard. This is a wider view (f/6) and a 72 minute exposure using 1 minute subframes and stacke in Pixinsight. To the lower left is the so-called "Running Man" nebula (can you see the runner?).




December 22, 2017
My first picture of Orion with the Celestron 11" Edge HD. This image was made December 22, 2017 using 15 of the best 30 second images then stacked in Photoshop CC to yield a 3 and a half minute exposed picture.
Camera used was Canon T2i at ISO setting of 1600
