2 Panel Mosaic featuring Gum 17 nebula.
Reminds me of Cosmic Cotton Candy on a Stick!

Taken from suburban Melbourne, Australia.

Probably a bit light on for data as we had a patch of cloudy and uneven nights with short clear breaks – but was keen to get what data I could prior to passing on my faithful QSI 683 wsg-8 to it’s new owner. This camera has served me very well for five years, but I’ve now got the big QSI 6162 to play with!

About this Nebula

The plane of our Milky Way Galaxy runs through this complex and beautiful skyscape. Seen toward colourful stars near the northwestern edge of the constellation Vela (the Sails), the mosaic is centered on the glowing filaments of the Vela Supernova Remnant, the expanding debris cloud from the death explosion of a massive star. Light from the supernova explosion that created the Vela remnant reached Earth about 11,000 years ago. In addition to the shocked filaments of glowing gas, the cosmic catastrophe also left behind an incredibly dense, rotating stellar core, the Vela Pulsar. Some 800 light-years distant, the Vela remnant is likely embedded in a larger and older supernova remnant, the Gum Nebula. Objects identified in this broad mosaic include emission and reflection nebulae, star clusters, and the remarkable Moustache Nebula. (text: Apod)
