Still another image! The Thor’s Helmet

A new image has been uploaded. This time it concerns NGC 2359, the Thor’s Helmet Nebula.  It is a beautiful emission nebula, imaged in narrowband (HII and OIII). Being a Hydrogen and Oxygen rich nebula, these two filters should provide the “natural” color. In my opinion, this is the case…

  2. Eng: It has surprising colors and definition. It also gives an idea of proximity with very clear shapes. It might be easy to compare its evolution along the time…

    Cat: És sorprenent en claretat i colors. També dóna una idea de proximitat amb formes molt definides. Potser serà fàcil de comparar amb el pas del temps la seva evolució.
