Caldwell 63
Caldwell 63, also known as NGC 7293 or the Helix Nebula, is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, most likely before 1824, this object is one of the closest of all the bright planetary nebulae to Earth. The distance, measured by the Gaia mission, is 655±13 light-years. Its age is estimated to be 10600 years. It is similar in appearance to the Cat's Eye Nebula and the Ring Nebula.
Caldwell 15
Caldwell 15, also known as NGC 6826 is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "Blinking Planetary". A distinctive feature of this nebula are the two bright patches on either side, which are known as Fast Low-Ionization Emission Regions, or FLIERS. They appear to be relatively young, moving outwards at supersonic speeds. Caldwell 15 is located at approximately 2000 lightyears from Earth.
Caldwell 39
Caldwell 39 (NGC2392) is a bipolar double-shell planetary nebula (PN) in the constellation Gemini. The Sun-like central red star is surrounded by gas that it has emitted from its outer layers. The visible inner filaments are ejected by a strong wind of particles from the central star.
Caldwell 2
Caldwell 2, also known as NGC 40 or the Bow-Tie Nebula, is a planetary nebula located in the constellation Cepheus. The nebula is approximately 3,500 light-years away from Earth. It is a very small object, with an apparent diameter of only 0.9 arcmin.
Caldwell 56
Caldwell 56, also known as NGC246, is a planetary nebula in the constellation Cetus. The characteristic shape of the bright outer shell has given it its nickname Skull Nebula. It is photographed here as an HOO image. The central white dwarf is resolved from its companion.
M57
M57, or the Ring Nebula, is a small planetary nebula in the constellation Lyra. Usually, only the core is captured in images, but this photo also shows the outer hydrogen (Ha) and oxygen (OIII) gas clouds. The difference is significant, so two different HDR methods were needed to achieve this result.
Caldwell 6
Caldwell 6 is a beautiful planetary nebula in the northern skies, nicknamed Cat’s Eye Nebula. A particular challenge is to pull out enough detail from the super bright nucleus while still seeing the intricate details of the filaments in this emission nebula.

The Crab Nebula is a supernova remnant and pulsar wind nebula in the constellation of Taurus. Imaged here in a Hubble Palette. This is the first image using BlurXTerminator for deconvolution, which is nothing short of a revolution in PixInsight image processing.
