Albireo Beta Cygni. Situata all'estremità della costellazione del Cigno, è una stella doppia tra le più famose. È considerata una delle più belle stelle doppie del cielo poiché è costituita da due stelle di colore contrastante: la principale è di colore arancio mentre la secondaria, di classe B8, è di colore bianco-azzurro. Con un piccolo telescopio mostra già le sue due componenti ed i suoi cangianti colori. Albireo A, di colore giallo/arancio è una gigante arancione con un raggio 50 volte maggiore del nostro Sole, ma una temperatura superficiale più bassa.Albireo B, è invece una stella bianco-azzurra con una temperatura superficiale molto più elevata di quella del Sole.Pur essendo conosciuta come sistema doppio in realtà è un sistema "triplo" perchè Albireo A è a sua volta una stella doppia, ma la sua compagna è irrilevabile da trumenti amatoriali.

Hello Serafix, thanks for the compliments.
The area is gorgeous, it always leaves me breathless. :-P
The instrument is the usual 10" RC f5.6. I'm glad I got a field all in all flat enough to get point stars almost to the edges.
Greetings
Gp

Hello Giancarlo, very glad you liked it.
Personally I am happy to have obtained a certain cleanliness and a sufficiently leveled field after the last retouching of the optics.
Let's say it's a good workout for the next galaxy season. :-)
Greetings
Gp

Hi Max
thanks, no course, I am self-taught since the age of 15.... then they were just paper maps of the sky, wake up in the middle of the night, darkroom for the first photos and a lot of passion and curiosity.
Hello
