I’ve mentioned the Sadr region before. The bright star in this image is Sadr, or Gamma Cygni, or the intersection of the wings and the main body of Cygnus the Swan. The dark nebula separating the two glowing nebulae is B 347 while the other two are IC 1318 and IC 1318B. This was made from 43 sixty second images using my 11″ SCT with Hyperstar and an L-eNhance filter. Taken Thursday evening from the River Ridge Observatory.
As a follow-up to the DSLR image of the North American Nebula that I posted yesterday, Sunday evening I went back to the River Ridge Observatory and did a close up of that nebula and the adjacent Pelican Nebula. I used my 11″ SCT with Hyperstar and L-eNhance filter to shoot in three narrow frequencies. Each image is made from 40 sixty second images. I did a minimum of processing this morning as I had to get to work.In the first image you see the shape of North America and specifically the “Cygnus Wall” in “Mexico” and “Central America”. On the right hand edge you can see the start of the Pelican Nebula which is the focus of the second image.
Here we have the Sagittarius Star Cloud taken Friday night with a Canon EOS 800D and 75-300mm kit lens at 80mm. ISO 3200 and about 40 sixty second frames stacked. It’s in the center and looks like you had pressed your left thumb against the glass. The bright clump in the lower left is the Lagoon Nebula and the one two the right, horizontal to the cloud and halfway to the edge is the Eagle Nebula. This is toward the center of our galaxy and a busy part of the sky.According to Wikipedia, “The Sagittarius Star Cloud (also known as Messier 24 and IC 4715) is a star cloud in the constellation of Sagittarius, approximately 600 light years wide, which was discovered by Charles Messier in 1764. It is sometimes known as the Small Sagittarius Star Cloud to distinguish it from the Great Sagittarius Star Cloud located to the north of Gamma Sagittarii and Delta Sagittarii.”.
