NGC6914

italy_flag_small

La regione, il cui oggetto principale è la nebulosa ad emissione NGC6914, essendo prossima al piano dell’equatore galattico, è molto ricca di oggetti.
NGC6914 è una vasta regione HII: la sua associazione con la grande nebulosa IC1318 ed i suoi tenui filamenti rossastri è ben evidente e l’intero complesso si trova alla distanza di circa 5500 a.l., trovandosi così nei pressi dell’associazione Cygnus OB2. La nebulosa riflette la luce azzurra della stella BD+41°3731, avente classe spettrale B3 e una magnitudine 9.84; essa presenta forti linee di emissione ed è classificata come stella Be.
Dello stesso complesso nebulare fa parte anche la nebulosa a riflessione VdB132, a sua volta illuminata da BD+41°3737, una stella azzurra di sequenza principale avente classe spettrale B3V e una magnitudine 9,27
Un oggetto peculiare presente nella ripresa, visibile al centro in basso, è la nebulosa a riflessione GN 20.22.7, illuminata dalla stella HBC694.

This region, whose main object is the emission nebula NGC6914, being close to the galactic plane of the equator, is very rich in objects.
NGC6914 is a huge HII region: its link with the large nebula IC1318 and its subtle reddish filaments is evident and the whole complex is located at the distance of about 5500 A.L., which places it near the Cygnus OB2 association. The nebula reflects the blue light of the star BD + 41 ° 3731, having spectral class B3 and magnitude 9.84; it has strong emission lines and is classified as a Be star.
VdB132 is a reflection nebula part of the same complex, in turn illuminated by BD+41°3737, a blue star of main sequence having spectral class B3V and a magnitude 9.27.
Another peculiar object is in the shot, visible at the bottom center: it is the reflection nebula GN 20.22.7, illuminated by the star HBC694.

Sh2-273

The complex molecular nebulous Monoceros OB1, also known as Complex Cone Nebula or the initials of the catalog Sh2-273, is a large H II region connected to a giant molecular cloud, situated in the direction of the constellation; It includes several reflection nebulae and other dark regions, as well as the famous Cone Nebula, located in a central position with respect to the cloud. It is about 2480 ly from the solar system, on the outer edge of the Orion Arm. The region is ionized and excited by the massive stars Monoceros association OB OB 1, which coincides almost entirely with the open cluster known as NGC 2264. The complex is also associated with the famous Hubble’s Variable Nebula, visible on the left side of the image, a cloud of cometary appearance generated by the star R Monocerotis, located inside.(Text adapted from Wikipedia)

Sh2-160

Continuo finalmente a mettere mano a file grezzi che attendevano di essere elaborati. Questa, tanto per chiarirsi, è una mia ripresa del 2014. Rispetto a come elaboro di solito le regioni ad emissione e vista anche la debolezza di quest’ultima, ho deciso di mantenere l’apporto di H-alfa meno invadente: questo proprio anche per sottolineare quanto deboli siano queste strutture.

Come sempre cliccando sulla ripresa qui sotto verrete portati sul mio sito dove potrete vedere una versione a risoluzione più alta e qualche informazione sulla ripresa.

AstroScheduler: una tipica sessione di ripresa

italy_flag_small

L’appetito vien mangiando ed avendo AstroScheduler in fase beta, posso cominciare a divertirmi. Ho iniziato quindi a riprendere, in notti diverse, la galassia IC342 nella Giraffa. Le riprese sono concluse, ma non sono state ancora elaborate. Ci tenevo però a farvi vedere il log di una notte di osservazioni automatiche di AstroScheduler.

Being AstroScheduler now in Beta version, I may start to have fun with it. I began to image, in different nights, the galaxy IC342 in Camelopardis. The imaging session on this galaxy is completed, but the image is not processed yet. However I wanted to show you a log of a full automated night of imaging by  AstroScheduler.
