In the news!

SBIG Camera user wins the overall 2019 CWAS David Malin Award

and the Deep Sky prize for the third year in a row.

(M42 overall winning image above, image Copyight Peter J Ward 2018, 2019)

World renowned Astrophotographer, Dr David Malin's (OAM) citation "This is a vivid and astonishing rendition of the well-known Orion nebula.

While it's the vivid red of the ionized hydrogen that catches the eye,

the picture also reveals the subtle texture and shading of the dusty regions around and within it.

This is one of the finest images of this object (M42) that I have ever seen.
