This image was captured by the Cuyahoga Astronomical Association’s member Lonnie Dittrick. The astrophotographer reports it took “fifty-two 90-second light frames over two nights (fighting waning gibbous moon and smoke from Canada)” from his backyard in Northeastern Ohio.

The North America Nebula (NGC 7000 or Caldwell 20) is an 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.” — Wikipedia

The Beautiful “Gulf of Mexico”

“Gulf of Mexico” Region of NGC7000

CAA member and local astronomy business owner Joe Golias has shared a new image with us that, well, all we can say about it is that it’s astounding! Here’s Joe’s description of how he produced his photograph of a region of NGC7000…

This was by far the most challenging imaging project I have attempted to date. It represents a four-panel mosaic of an area called the “Gulf of Mexico” which is part of a much larger area of nebulosity called The North American Nebula or NGC7000. This object is located in the constellation of Cygnus. This four-panel mosaic was acquired over a period of three weeks. Total exposure time was 56 hours. We’ve had a long stretch of clear skies here in Ohio which made this image possible.
