M42 &M43 The Great Orion Nebula _ A stellar Nursery the closest to Earth. This star birth region is 1, 344 light years awayand is about 24 light years across.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky!!
My first Test of an Emission Nebula with my unmodified Canon 6D DSLR at the Prime Focus of my Home-built 16″ Diameter F4.5 Newt. telescope.
This is a quick 97 second exposure,
actually two shots layer Masked, to prevent over exposure!  A 7 second exposure for the center Trapezium region and a 90 second exposure for the full nebula is all it took to record this.
ISO was set at 3200. The Canon 6D tends to be a little more Blue/Green sensitive…a little noise in this image at 70F, but it does the trick if you need a quick image before the clouds roll in!!!
Transparency was not the best Friday night…but now I know it is easily capable of recording bright red Emission Nebula quickly!
Pretty impressive & sensitive for an unmodified DSLR.

This was just a test under poor sky conditions, so the next clear night I will go back and do a longer exposure & fully glory shot!

Best Regards,
