Description

This region of the North American Nebula (NGC7000) is known as the Cygnus Wall.  It is a massive star forming region that is roughly 1,500 light years away from Earth in the Cygnus constellation.   The colloquial name for NGC7000 comes from this large nebula's resemblance to the North American continent.  In terms of that orientation, this image is a close up of the Mexico and Central America region with the Gulf of Mexico at the top of the image.  The region visible in this image is roughly 15 light years wide.  

This is an SHO image but I really tried to render this in a more natural color pallet.  I have been agonizing over multiple version revisions for days looking for the perfect balance between background and foreground while working with pixel math in PixInsight to fine tune the color pallet and bring out fine details.  All three channels are strong in this image so it was a real challenge to isolate the colors of the features and render them in a detailed way.  

For now, I have settled on a version where I used a luminance layer made with just Ha and Sii and stretched with GHS.  I wanted to create a bit of depth in the image and by going this route, I de-emphasized some of the Oiii detail in the background.   It is easy to drive yourself crazy looking at various options.   I left some of the prior revisions on the page so feel free to flip through them. 

This was one of the images that I captured over the past few weeks of glorious weather in South Florida.    Clear nights and good seeing provided a bonanza of data collecting after a long wet summer.  Unfortunately we are back to summer conditions over the next 10 days or so and even a strange November tropical storm.  So this will be the last image for a while.

Thanks for stopping by.
