NGC6888_BiColour_15-6-2023

            This image is dedicated to my Uncle Ron who served in the RAF during World War II. He passed away last month at the age of 98 around the time this image was taken.

My first summer Nebula taken around the time of shortest night where even down south Astronomical Twilight doesn’t finish. Due to this I could only image between midnight and 2am, I was surprisingly fortunate to get 4 clear nights in succession. Though I have imaged this before this is the first time with a wider field scope and therefore managed to include the soap bubble in the top right.

OBJECT DESCRIPTION:-
NGC 6888 the Crescent Nebula is in the constellation of Cygnus and approximate 5,000 ly from earth with a visual mag of 7.4. It structure is formed by the star shedding its outer layer in a strong stellar wind interacting with slower moving material shed at an earlier time. The star is at the end of its stellar life and will eventually result in a Supernova.
Also included in the top right is the Soap Bubble Nebula (PN G075.5+01.7) a planetary nebula. It was discovered by amateur astronomer Dave Jurasevich in 2007/08.
