Caldwell 39 (NGC2392) is a bipolar double-shell planetary nebula (PN) in the constellation Gemini. It was discovered by William Herschel in 1787. The formation resembles a person's head surrounded by a parka hood. It is surrounded by gas that composed the outer layers of a Sun-like star. The visible inner filaments are ejected by a strong wind of particles from the central star.

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, 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.

Sh2-290 is a faint planetary nebula in the constellation Cancer. It is a typical dual band colour image, with relatively strong signals in Ha and OIII. This image is captured using a total of 20h of exposure. Sh2-290 is a member of the Sharpless catalogue of HII regions.

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.

M76 is also known as the Little Dumbbell nebula, a small but bright Planetary Nebula in the constellation Perseus. Here imaged using HOO narrowband imaging.

M27 is a very bright planetary nebula, of which often only the core is shown. In this case, the outer and much fainter areas are made visible as well in this HOO image, using a new HDR script.

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.

M97, or the Owl Nebula, is a small planetary nebula in the constellation Ursa Major. Using Halpha and OIII narrowband filters enabled imaging while the moon was out at almost 100%.

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.
