Image Description and Details :

This image shows the area of sky above the constellation of Orion. In the top right, looking like a comma is the Flaming Star Nebula. Just to the left of it is the Tadpole Nebula. If you look at the high resolution image on my website you can see the tadpole shaped structures inside it that give it its name. To the upper left is Sharpless 232 which I always think looks like a person running in a hamster wheel! To the bottom left is the large supernova remnant Simeis 147 aka the Spaghetti Nebula. This is a 16 image mosaic taken at a focal length of 530mm with a 4 inch refractor. 171 hours of light was collected through H-alph, SII and OIII filters.
