NGC1365 | The Great Barred Spiral Galaxy | LRGB
The beautiful and majestic barred spiral galaxy, NGC1365, lays in the depth of space some 56 million light-years away in the constellation of Fornax. But NGC1365 is not alone, as it forms part of the enormous Fornax galaxy cluster which is said to be the second most richest galaxy cluster within 100 million light years from earth [with the Virgo cluster of galaxies being largest].
This galaxy shows intense star forming regions, defined by the pinkish, magenta tones surrounding the galaxy core and out into and along its arms. The nature of this barred typed spiral galaxy resides in the shape of its core, and how it extends to its arms. With highly defined dust lanes that etch across this bar section, the barred shape is easily confirmed. Astronomical studies reveal the gravitational nature of this bar structure serves as a perfect funnelling mechanism, channelling stellar material, such as stars, dust and gas, towards the centre that ultimately feed a discrete, super-massive black hole.
Matter of interest: To the right of NGC1365, and between what seems to be a distant elliptical galaxy, are a number of very faint and possibly fine galaxy arm extensions, or tidal tails that may be associated to NGC1365. Their positions extend out far and wide of that of the main structure. This observation may only be that of coincidentally aligned structures.
This image was captured over the months of October to November 2019, with the top 23 hours of sub-exposures taken with Luminance, Red, Green and Blue filters. These sub-exposures were individually calibrated and then medium combined to create a master filter set. This master set was then combined and edited to create this final image.
