Triangulum Galaxy – M33

The Triangulum Galaxy (M33, NGC598) the third largest member of the local group, with its larger sisters the Andromeda Galaxy and our Milky Way. It consists of 40 billion stars, really small compared to the 400 billion of the Milky Way and the 1 trillion of the Andromeda Galaxy. This in an LRGB image of […]

Usually we admire the mysterious blue glow of the reflection nebula diverting the light of the embedded magnitude 7 star, SAO 19158. However, there […]

Dark nebulae are something completely out of reach for my usual imaging conditions… pitch black skies and long exposures are mandatory. Deep Sky West offers both, so dark nebulae are a prime target for RGB imaging there. This is the “Howling Wolf” Nebula, consisting of a collection of objects, i.e., vdB 149/150 and LDN 1235. […]
