Imaging Projects

In this blog, I will share the results of all of my imaging projects. The newest will be at the top and the oldest will be further down the stack. Going back in time here is interesting - some of my early stuff was pretty rough - but I did not see it that way at the time - I was thrilled to get anything back that looked like an image! Hopefully, you will see how my work has progressed with time!

NGC 6820 and NGC 6823 - An Open Cluster w/Nebula - A Grudge Match…

Located in the constellation Vulpecula, NGC 6823 is a small open cluster of stars and associated nebula, NGC 6820. The cluster is about 6000 light-years away and measures about 50 light-years across.

A year ago, I shot this, and it was one of the worst images in my collection. I came back again this year to reclaim my honor and vanquish this target foe!

NGC 7000 (The North American Nebula) with IC5070 (Pelican Nebula) in Narrowband- Total of 9.33 Hours

NGC 7000, also known as the North American Nebula and Caldwell 20, is a large H II emission nebula located in the constellation of Cygnus (The Swan). It measures roughly 2 degrees by 1.5 degrees in size, making the nebula about 10X larger than the area covered by the full moon.

Also included in this view is the Pelican Nebula IC 5070

This image is the result of 9.33 hours of integration in Narrowband and rendered in the Hubble Palette.

Extensive notes on image processing are included for the first time.

SH2-101 - The Tulip Nebula - 12.8 Hours in SHO

SH2-101 - The Tulip Nebula - 12.8 Hours in SHO

Sharpless 101 (specifically Sh2-101) is also known as the Tulip Nebula and is located approximately 6000 light-years away in the constellation of Cygnus (The Swan). Steven Sharpless first cataloged this rich H II emission region in 1959 in his second catalog of nebulae. Early photographic images of this area resembled a flower, and this gave rise to its common name.

This was a 12.8-hour integration with the AP130 platform using the ZWO ASI2600MM-Pro Camera.

Messier 8 - The Lagoon Nebula In the Hubble Palette

Messier 8, also known as the Lagoon Nebula and NGC 6523, is a huge cloud of molecular gas and dark dust located about 4000-6000 light-years away in the constellation Sagittarius. This is a large emission nebula that is bright enough to be seen with the naked eye. Within the cloud is the open cluster NGC 6530, and a bright central feature is known as the Hour Glass.

This is my third effort on this target - a mono image in SHO - working from minimal data taken the troubling month o July 2021
