The Tulip Nebula SH2-101

 

Το Νεφέλωμα της Τουλίπας(Sharpless 101) είναι νεφέλωμα εκπομπής στον αστερισμό του Κύκνου. Απέχει περίπου 6,000 έτη φωτός από τη Γη και η διάμετρός του υπολογίζεται στα 70 έτη φωτός.

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

The Wizard Nebula

The Wizard Nebula is an emission nebula that surrounds the open star cluster NGC 7380 in the constellation Cepheus. The nebula is known for its unique shape, resembling the appearance of a medieval sorcerer. The active star forming region lies at a distance of 7,200 light years from Earth and has an apparent magnitude of 7.2. It has a radius of 100 light years and occupies 25 arc minutes of the apparent sky. It has the designation Sh2-142 in the Sharpless catalog of H II regions.

i totally reprocessed my previous published image of Wizard Nebula,hope you like it...

Whirlpool Galaxy M51

The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus.It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. Its distance is estimated to be 23 million light-years away from Earth.
