NGC 6888 - Crescent Nebula & More

The feature of this image is the Crescent Nebula or NGC 6888 which is an emission nebula in the constellation Cygnus approximately 5,000 light-years away. It formed when a highly energetic fast moving stellar wind encountered slower moving wind ejected when the star became a red giant over 250,000 years ago. It is currently 25 light-year across. This whole region is loaded with gas and dust as can be seen on the image. In addition to the high amount of hydrogen in and around the Crescent Nebula, a high amount of Oxygen is also present. The hydrogen is represented as red while Oxygen appears as a blue-green color. Also, found on this image is the Soap Bubble Nebula (PN G75.5+1.7). Located on the left side the Soap Bubble Nebula is a planetary nebula and was discovered less than 20 years ago.

This is my second image with the Celestron EdgeHD8 with Hyperstar. I once again used the IDAS NBZ dual band filter and the ZWO ASI294MC Pro. So far I am very happy with the results and look forward to continual use.

I made a video short (< 1 min.) of both the EdgeHD8 and AT115EDT setups if you want to see more.
