| Info |
Ngc 300 is a 9th magnitude spiral
galaxy (sc type) located in the Sculptor group of galaxies, in the constellation of
Sculptor. It's estimated distance
is around 7 million L.y. It has a very low surface
brightness. Originally
discovered from Australia by the Scottish astronomer James Dunlop in the
early 19th century, NGC 300 is one of the closest and most prominent
spiral galaxies in the southern skies and is bright enough to view easily
through binoculars. |

| Notes/ Conditions |
Conditions- Average seeing and transparency when taking the lum on both nights. When taking the colour set, the evening was also average. This galaxy is extremely faint and to better resolve the core, larger apertures, super dark skies and far more exposure time than used hear would bring out and resolve the fainter stars that appear as smudges in my image. |
