M42 & M43 The Great Orion Nebula, an Awesome Stellar Nursery – Star Formation Region!  One of the most amazing objects to see through a telescope!  Who would like to explore this gaseous Cloud with me???
I pulled an all-nighter at my observatory using my Canon 6D DSLR attached to my 16″ scope ..and took lots of Data on many objects.
I’ll be processing images for weeks to come, but this one of M42/M43 in Orion was a two exposures stacked, one at 4 minutes for the outer regions and 1 at 30 seconds for the trapezium region.   ISO-3200, 10-26-2014 3:06am
and still working out my coma corrector configuration, also still a tad bit of vignette near corners with the large chip for this setup, but
I was amazed at what my new Unmodified Full Frame Canon 6D pulled out in less than 5 minutes through my Home-built 16″ Diameter F4.5 Fork Mounted Newt. Telescope. The camera seems to be more green blue sensitive than others, yet still able to record the red nebula regions well, and at higher ISO seems a lot cleaner (less noise) than previous DSLRs.
Although it did take me about 4 hours to carefully process it though!! Thanks to my winning the National Science Foundation/Discover Magazine/Astronomy Mag’s International Comet ISON Photo Contest, with the 1st place Award money I was able to buy this new camera a bit sooner than I had thought! ..Now I’m looking forward to many more quick and painless captures of the sky!Best Regards,
