The North America Nebula (NGC 7000 or Caldwell 20)
The North America Nebula is an emission nebula in the constellation Cygnus, close to the bright star Deneb. The shape of the nebula resembles that of the continent of North America,
complete with a prominent Gulf of Mexico.
This Massive Stellar Nursery(star formation region) is located at 2,500 light years from Earth and spans about 100 light years across.
Also visible to the top right is the Pelican Nebula (IC 5070), part of the same larger North American Nebula complex.
This is 120 x 60 second subs exposures stacked, all taken from my backyard in the city of Dayton, Ohio. (2 hour total exposure)
I used an Optolong L-Pro 2″ Filter which knocks out the city light pollution, so it allows you to image/take deep space photos from the city. This is strictly visible light from deep space, with Light pollution removed via the filter.
I have used many types of light pollution reduction filters in the last 30 years of imaging, but most of them did not work as well as they claimed, or gave really strong color casts or strange gradients when imaging with color or mono cameras.
But this one really works well…
I love that I captured this using just a 135mm telephoto lens and ASI Air(2nd gen) and my old ZWO174 cooled camera, Bisque MyT mount, all controlled with an App on my IPAD.
Every 60 seconds a new image appeared on the IPAD, including some with satellites passing by and an occasional Aircraft buzzing through this(4.8 degree x 3 degree) wide field of View.
All automated while watching a movie, image processing other data, or even sleeping in my home, with an occasional glance at the Ipad Screen to see the progress of the images being acquired.
The technology just keeps getting better!!!!
