M8 composite (LHa)(RHa)GB by Ignacio Diaz Bobillo Via Flickr: Added 5.5 hours of H-alpha data to an old OSC image. The H-alpha data was added to the luminance and red channels, in different proportions, to achieve a pleasant color balance.

IC4592 – The Blue Horsehead Reflection Nebula by Leonardo Orazi Via Flickr: http://ift.tt/1IjP4zU Do you see the horse’s head? What you are seeing is not the famous Horsehead nebula toward Orion but rather a fainter nebula that only takes on a familiar form with deeper imaging. The main part of the above imaged molecular cloud complex is a reflection nebula cataloged as IC 4592. Reflection nebulas are actually made up of very fine dust that normally appears dark but can look quite blue when reflecting the light of energetic nearby stars. In this case, the source of much of the reflected light is a star at the eye of the horse. That star is part of Nu Scorpii, one of the brighter star systems toward the constellation of the Scorpion Scorpius. A second reflection nebula dubbed IC 4601 is visible surrounding two stars on the upper right of the image center.

OWL CLUSTER + Friends by Jaspal Chadha Via Flickr: NGC 457 (also known as the Owl Cluster, the ET Cluster, or Caldwell 13) is thought to be about 21 million years old, and about 7,900 light years from Earth. It contains about 150 stars. There are at least a several dim galaxies in the field, all 17th magnitude or fainter. Colour is a function of temperature (redder is cooler; bluer is hotter) there are several galaxies in the view of field Few galaxies that confirmed by SIMBAD Database 267 Million Light years PGC 2528351 galaxy (15+ Mag) PGC137485 galaxy (15+ Mag) PGC 4831 galaxy Technical Data Date: 19/07/2015, London UK ( Poor conditions ) Telescope: Altair Astro RC 250TT with Focal reducer QHY9S MONO CCD Chroma Technology filters L 5 x 300 seconds RGB 5 x 300 seconds Ioptron CEM60 mount

The Great Foot in Sagittarius by Rick Stevenson Via Flickr: The Lagoon Nebula, Messier 8, combines with the complex including NGC 6559 to look like a giant foot. The Trifid Nebula, Messier 20, floats above in the top right. Approximately 6 hours of LRGB data captured with a Takahashi FSQ-106ED scope and STL11K camera. Processed with PixInsight.
