Mandel Wilson 9 in Apus
This wide-field image explores the complex of faint galactic cirrus known as Mandel Wilson 9 in the far southern constellation Apus- the final entry in Mandel and Wilson's "Catalogue of Unexplored Nebulae"
The light of stars in the Milky Way are reflected by these cosmic dust clouds that soar 300 light-years or so above the plane of our galaxy. Amateur astronomers refer to these as integrated flux nebulae though astronomers I believe prefer to call these galactic cirrus. These clouds commonly found at high galactic latitudes are incredibly faint and there is a barely a hint on individual sub exposures. But they can be traced over large regions of the sky toward the North and South Galactic poles. Along with the reflection of starlight, it is reported that studies suggest the dust clouds produce a faint reddish luminescence as interstellar dust grains convert invisible ultraviolet radiation to visible red light..,there is I feel a hint of rust in my image.
If you look closely you can see two tiny galaxies shining through the cirrus- a face on spiral (IC 4733) and a edge on galaxy below (IC 4635)
8 hours of integration over two sessions separated by nearly 24 months. 300 second subs
