IC1848 Soul nebula

Soul nebula is a beautiful HII region, where new stars are being born. It’s located in constellation Cassiopeia and it’s 7500 light-years from Earth. The nebula has neighbor Heart Nebula (IC1805). One can say that in this constellation the heart and soul are close to each other.

As usual, I used narrow band filters to capture this spectacular nebula. It didn’t fit into ma field of view; this means I would need shorter focal length.

IC5070 Pelican nebula

Pelican nebula is large cloud of hydrogen gas, where many stars are being born, located in constellation Cygnus (Swan). The nebula is approximately 2000 light-years away from Earth. If you use bit of an imagination, you will be able to see the pelican in the dark cloud surrounding the brighter center of the nebula – good luck with searching.

The picture was taken completely by narrow band filters. The first one is in “fake” Hubble palette and second one as a bi-color image (Ha in red channel, OIII in green and blue channel).

NGC6604 Open cluster

NGC6604 is an open cluster associated with nebulosity. It is located not far from my favorite Eagle nebula in constellation Serpens and it’s 5500 light-years far from the Earth. Since this deep space object is not that high on the skies, I rather used narrow band filters, because this part of the skies is strongly influenced by the light pollution, which is coming from the nearest town. First picture is processed in “fake” Hubble color palette, the second one should more or less look like in “true” color.
