The star-forming region around NGC 6726 in the southern constellation of Corona Australis (Southern Crown) about 400 – 500 light years distant is a complex association of dust and beautiful blue reflection nebula. In the image, the globular cluster NGC 6723 is also seen. Though prospectively near th...

VdB 152 is a dark nebula located about 1400 light-years away in the constellation Cepheus. Part of these interstellar clouds, which become visible only in long exposure photos, is illuminated by the reflected light of a nearby star, giving the upper part its characteristic blue-blue color. SkyWatche...

VdB 141 or Sh2-136, commonly known as the Phantom Nebula because of its shape, is an isolated Bok globule. Bok globules are the areas inside a nebula where gas condenses and new stars begin to form. This nebula is immersed in a large area of interstellar dust that weakly reflects light from nearby s...

The galaxy NGC 6946, also known as the Fireworks Galaxy due to the large number of supernovae discovered within it, is a beautiful spiral galaxy located about 10 million light-years away. Nearby, but only apparently, there is a cluster of stars: NGC 6939. In reality, this object is part of our galax...

The famous constellation Cassiopeia is immersed in the Milky Way. This causes its iconic W shape to be virtually unrecognizable in this long-exposure photo taken from the excellent sky of Lama Lite. On the other hand, some emission nebulae with their characteristic red color are clearly visible. Fro...
