NGC 6992/6995 Nebuolsa Velo est sent on September 07, 2015 (10:34) by _elio_. 5 comments, 865 views.

NGC 6992/6995 Nebuolsa Velo est è appunto la porzione est della nebulosa Velo un antico resto di supernova nella costellazione del Cigno: la stella che ha originato quest'oggetto è esplosa diversi millenni fa. Ciò che ora è visibile sono dei debolissimi filamenti, ancora in espansione alla velocità di decine di km/s; dell'intero complesso si distinguono diversi filamenti disposti in tre gruppi principali: il più ad ovest è quello di NGC 6960 (C 34), in direzione della brillante stella 52 Cygni; il secondo, poco più ad est, è formato dalle nebulose NGC 6974 e NGC 6979, e quello ritratto in questa fotografia astronomica che è formato dalle sezioni NGC 6992 (C 33) e NGC 6995 (ai quali si aggiunge IC 1340), orientato in modo speculare rispetto agli altri due, conosciuta anche come Nebulosa Rete. Si pensa che nel giro di pochi millenni questa "meraviglia" del cielo boreale scomparirà, perché ad una grande velocità di espansione corrisponde pure un elevato indice di dispersione della sua materia, che presto esaurirà la sua energia ricevuta durante l'esplosione, e si disperderà nel mezzo interstellare, "quasi" senza lasciare traccia. L'immagine di seguito è il risultato di una astrofotografia di circa 5 ore ripresa dal cielo della Sabina con una reflex Canon Eos 60D raffreddata e modificata, utilizzando un rifrattore Takahashi FSQ85ED, montato su Avalon M-Uno autoguidata con Lacerta MGen.

Hi Alessandro,
very nice photo.
Both signal for an SLR, field perfectly paved, good sharpness, perfect colors.
I seem to see the stars on the nebula very bright compared to the others, at least on my monitor, maybe pulling the signal in that area were a bit 'on.

Fab ... Bal ... I will forgive the slight delay ... but I read just now: - | I know they are a perennial rinco ...: - /

Fab were right (you ...) unfortunately the flat did not work well and pulling a bit the signal seems that in some areas has a crush ... :-)

Bal ... at Mt. Palomar would serve a large mosaic, if I remember, to take up this beauty :-)

however, it, technology is advancing dramatically and continually, with new techniques and computing ...: -o

a warm greeting, and again apologies for inattention! : - |
