Η λήψη έγινε πριν λίγες ώρες από την κορυφή της Πεντέλης. Την επόμενη φορά θα δοκιμάσω με το τηλεσκόπιο να τον φωτογραφίσω. Canon EOS 450d Canon EF 200mm f/2.8 L 4 sec, ISO 800

The Cygnus Wall is a ridge of star-forming gas and dust about 20 million light-years long in the North America Nebula, NGC 7000. Like a mountain range carved by the erosion of water and wind, the Cygnus Wall is shaped by the energetic radiation of the young, hot stars nearby. The dark shapes that snake through the ridge are cooled gases and dust, the birth place of new stars.

Not much can be said or read about Sh2-124 molecular hydrogen cloud in the north-east Cygnus frontiers. It is pretty large emission nebula, but not too bright. The whole area is filled with the hydrogen, so every place you look you can see red. Not much science work has been done there, it is even not certain which stars are responsible for exciting hydrogen to shine in red. Pretty mysterious nebulosity.

IC 5076 (vdB 137, DG 165, Ced 185, LBN 394 and others) is a reflection nebula located approximately 5,700 light-years away in Cygnus. The stars around it appear to also be cataloged as open cluster NGC 6991.

Ο σπειροειδής γαλαξίας της Δίνης (whirlpool), που είναι επίσης γνωστός και ως Μ51 ή NGC 5194, έχει μια καθαρή δομή βραχιόνων. Αλληλεπιδρά με τον γαλαξία NGC 5195 σε απόσταση 23 εκατομμυρίων ετών φωτός και βρίσκεται στον αστερισμό των Θηρευτικών Κυνών.

Το Νεφέλωμα του Καρκίνου (M1, NGC 1952), ή αλλιώς Νεφέλωμα Καρκίνος, είναι νεφέλωμα του Γαλαξία μας, που ανακαλύφθηκε το 1731 από τον Άγγλο γιατρό και αστρονόμο Τζον Μπέβις (John Bevis). Αποτελεί υπόλειμμα υπερκαινοφανούς αστέρα: ένα διαστελλόμενο νεφέλωμα αερίων, τα οποία τα είχε αποβάλει η έκρηξη υπερκαινοφανούς αστέρα που συνέβη στις 4 Ιουλίου 1054, κοντά στο άστρο ζ Ταύρου, και η οποία καταγράφηκε από τους Κινέζους αστρονόμους της εποχής στα Χρονικά της Σινίκης. Παίρνει το όνομά του από το σχήμα του, που θυμίζει καβούρι (καρκίνος) όταν παρατηρείται με τηλεσκόπιο.

NGC 7331 Big, beautiful spiral galaxy NGC 7331 is often touted as an analog to our own Milky Way. About 50 million light-years distant in the northern constellation Pegasus, NGC 7331 was recognized early on as a spiral nebula and is actually one of the brighter galaxies not included in Charles Messier''s famous 18th century catalog. Since the galaxy''s disk is inclined to our line-of-sight, long telescopic exposures often result in an image that evokes a strong sense of depth. The effect is further enhanced in this sharp image by galaxies that lie beyond the gorgeous island universe. The background galaxies are about one tenth the apparent size of NGC 7331 and so lie roughly ten times farther away. Their close alignment on the sky with NGC 7331 occurs just by chance. Seen here through faint foreground dust clouds lingering above the plane of Milky Way, this visual grouping of galaxies is also known as the Deer Lick Group.
