The North America Nebula (NGC 7000) is a large emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. The distance from earth is around 1600 light-years with a size of 100 light years, covering an area of more than four times the size of the full moon). (dixit Wikipedia )
To take this photo i used the following setup:
Scope: TSOptics 80/350
Mount: AZEQ6
Camera: Atik One 6.0
The total exposure is around 8 hours over 2 nights in july 2016. As my camera is black & white i use Hubble color palette by stacking and mapping to RGB a combination of:
9 photos of 20 min flitering around Ha ray of Hydrogen
7 photos of 20 min filtering around OIII ray of Oxygen
7 photos of 20 min filtering around SII ray of Sulfur
I used the software Prism 10 to manage the capture, the pre-treatment (Removing offset, dark and flat). The stacking and the post-treatment was done with Pixinsight and at the end Photoshop.
