Στο δεξί κάτω άκρο της φωτογραφίας ακριβώς κάτω από το αχνό τόξο που σχηματίζεται, έχει καταγραφεί η περιοχή που βρίσκεται η πρώτη υποψήφια Μαύρη Τρύπα Cygnus X-1 και μια από τις ισχυρότερες πηγές ακτίνων Χ του γαλαξία μας.
The Tulip Nebula (Sharpless 101) is an emission nebula located in Cygnus constellation. It lies at an approximate distance of 6,000 light years from Earth. It occupies an area of 16 x 9 arc minutes of apparent sky and has a linear diameter of about 70 light years
The Tulip Nebula is located in the same region of the sky as the microquasar Cygnus X-1, the first galactic X-ray source widely believed to be a black hole. Cygnus X-1 consists of a star, HD 226868, and a very small high-mass object. The two orbit around each other with a period of 5.6 days. The object was one of the first ever candidates for a black hole.
A new project begins...I hope to finish next year the other 2 narrowband filters
