The Tulip Nebula (SH2-101) & NGC 6871 SH2-101, also called the Tulip Nebula, is a glowing cloud of interstellar gas and dust in the constellation Cygnus. This nebula is about 8,000 light-years from Earth, and 70 light-years across in size. The Tulip Nebula gets its name from the flower it appears to resemble when photographed. This nebula was cataloged by American astronomer Stewart Sharpless in 1959. An interesting fact about the Tulip Nebula is its "close" proximity to the galactic X-ray source known as Cygnus X-1. Cygnus X-1 is one of the strongest X-ray sources seen from Earth and is the site of one of the first suspected black holes. Cygnus X-1 is thought to be a stellar-mass black hole, a class of black holes created by the collapse of a massive star. On the left, we can see NGC 6871, a small, young open cluster. This cluster has fewer than 50 members, most of which are blue and white stars. It is located 5135 light-years from us. For this one, I needed 3 nights to get some good result as the signal seems to be very faint (especially for the O3). With that, Waxing gibbous Moon and some clouds entered in the battle. :D I had some issue popping the blue O3, that's the reason I'll retry this object in the future, trying to get more details on the Nebula and its surroundings, Clear Skies :) Lights : 58 x 600 sec (9h40) Darks : 60 ~ Offset : 100 ~ Flats : 60 Setup : Camera : ZWO ASI 2600 MC Main Scope : Skywatcher Esprit 100 ED Mount : Skywatcher EQ6-R Guide Camera : ZWO ASI 120MM Mini Guide Scope : ZWO Mini Guide Scope Filters : Antlia ALP-T Others : ZWO ASIAIR PRO, ZWO EAF #SH2101 #NGC6871 #tulip #nebula #backyard #stargazing #nightimages #nightshooters #nightshots #astronogeek #astrobackyard #astrophotography #belgium #nightsky #deepsky #astronomy #space #asiair #antlia #zwo #2600MC #astrobiscuit #skywatcher #esprit #100ED
