#crescentnebula

My picture involved 9.5 hours of sub-exposures plus calibration frames, taken in Colchester, England, on a modified Nikon D750 DSLR, Sky-Watcher Explorer 150p, EQ5 Pro, via Stellarmate in Kstars/Ekos. Stacked in AstroPixelProcessor, cropped and adjusted in Photoshop and Lightroom.

These Merging Black Holes Have Been Discovered! This pair of black holes is known as “GW190521”, and they are slowly merging together to form a supermassive black hole! This pair of black holes lie approximately 17,000 million light years away, and was discovered by gravitational wave signals. If you are unfamiliar with black holes, allow me to explain: a black hole is a region in space where nothing can escape from it, not even light. A black hole forms when a massive star explodes in an event known as a supernova . . . #outerspacemag #outerspacestore #NGC6888 #crescentnebula #nebula #universetoday #OPTeam #ASIweek #natgeospace #apod #space #astrophotography #astronomy #cosmology #astronomyfacts #spirituality #stargazing #universe #telescope #astro #astronomer #astrophysics #elonmusk #spacepicture #spacex #nasa #nebula #universetoday #OPTeam #ASIweek #ZWOasi #astronomypicturesdaily #photography #natgeospace #apod #space #astrophotography #astronomy #cosmology #astronomyfacts #spirituality #stargazing #universe #telescope #astro #astronomer #astrophysics #elonmusk #spacepicture #spacex #nasa view all 106 comments https://www.instagram.com/p/CdupwH3pQQr/?igshid=NGJjMDIxMWI=

I couldn’t resist. The Crescent Nebula again. I used also images from a previous work so now total integration is 4.55 hrs. I used the l-enhance Optolong filter. Loving it! 53 pics * 300 sec.

NGC 6888 by infinitalavita https://flic.kr/p/29f9aK5

Located 5,000 light years away from Earth in the constellation Cygnus is the Crescent Nebula or NGC 6888. This gorgeous nebula is fascinating because it has a Wolf-Rayet star (WR 136) which is shedding layers at unfathomable speeds. This star is nearing the end of it’s stellar life and approaching the end-result as a violent supernova. The wind-blown nebula is sculpting gasses such as oxygen which can be seen in the blue-greenish hues. It’s ejecting the equivalent of the Sun’s mass every 10,000 years! What’s even more amazing is that this nebula stretches 25 light years across! That would be around 250 trillion KM across, which would be one long trip. The closest start to Earth is about 4 light years away so you can imagine this trip is a bit longer than going to the grocery store. It truly is incredible the amount of gas a star expels as well as the enormous amount of energy it releases towards the end of its life. This is a beautiful snapshot of what it looks like when a star is about to die and give birth to new stars like our own.  Photo credit: J-P Metsavainio #astronomy #space #astrophotography #Cygnus #CrescentNebula #NGC6888 #NASA #nebula #wolfrayetstar #wr136
