Every day our eyes catch the light of our memories – time spent with family, the journey to work, a special holiday, a beautiful sunset or a dark starlit night. Each image captured is a picture drawn in light – a photograph: only to be lost in our minds or forever forgotten. Nearly two hundred years ago a small group of amateur scientists achieved what had eluded mankind for centuries – the ability to capture a permanent record of an image seen by their own eyes – a moment in time frozen onto a surface. They had discovered Photography. They were the ‘Catchers of the Light’.

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
