Caldwell 23, also known as NGC 891, is a spiral galaxy located approximately 30 light-years away in the constellation Andromeda. Its striking edge-on appearance has given it the nickname Silver Sliver galaxy. The galaxy is very similar in structure to our own Milky Way.

M79 is a small globular cluster in the constellation of Lepus. It maximally rises only 28° above the horizon, so is on the edge of what can be imaged from the observatory in Spain. Still an overall 12h of data has been collected in December 2024 and January 2025.

M37 is the brightest open cluster in the constellation of Auriga. Many of its 500 stars are fairly young bright blue stars, but the big star in the center (HD39183) is a yellow giant. M37 is photographed here during two consecutive full moon periods in December 2024 and January 2025 respectively.

Sh2-292 is an emission nebula in the constellation Canis Major. It is the head of te Seagull nebula. Most images will show the full Seagull nebula using a fairly wide field setup. But the Sh2-292 designated area is only referring to the head, which is shown here in an SHO palette.

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.

M71 is a nice globular cluster in the constellation Sagitta at about 13,000 light-years away from Earth. The object is located near the dense star fields of the Milky Way, making it an intriguing object to photograph.

IC4954 and IC4955 are two very small nebulae in the constellation Vulpecula. The total field of view of this image is only 12 x 9 arcmin, so very much zoomed in on an already long focal length telescope. Each night only 0.5-1.5h of data could be collected, so this image is the result of 20 imaging sessions.

Sh2-200 is a very dim planetary nebula in the constellation of Cassiopeia. By mistake it ended up in the Sharpless catalogue of HII emission regions, but recently its identity as a planetary nebula was confirmed. The nebula itself and especially the hydrogen regions around it are very dim, so require long exposure times

Sh2-206, also called the Fossil Footprint Nebula, is a beautiful emission nebula in the constellation Perseus. It is photographed here using the Hubble palette, creating the typical blue/golden look. For processing, the relatively new NPColourMapper script was used.

Caldwell 5, or IC342, is also known as the hidden galaxy, tucked away behind the dust of our own Milky Way. Individual frames did not reveal too much detail, but stacking 20h of exposure brought out the full splendour of this beautiful galaxy.

M32 is a small dwarf satellite galaxy to its big brother Andromeda Galaxy. It is not photographed on its own, but the purpose of this image was to zoom in onto M32 itself. It is not a spectacular target, but photographed here in a closeup that is not seen very often.

M103 is a small open cluster of only 172 stars, in the constellation of Cassiopeia. It is located 9,400 lightyears from the Sun and includes some rather bright stars of magnitude 10.5. The object is photographed under full moon conditions.

M52 is an open cluster in the constellation of Cassiopeia. Star clusters like these are ideal targets to image during full moon, which is done here.

M110 is at first glance a somewhat boring galaxy, always in the shadow of its close and popular neighbour M31, the Andromeda Galaxy. The main reason of imaging was to complete the Messier catalogue. But some very small scale structure appeared to be present, which in the end made this a fun object to photograph.

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.

Arp78 is one of the 'Peculiar Galaxies' from the Arp catalogue in the constellation Aries. Tidal forces from nearby galaxies pull the arms of Arp78 into the peculiar shapes as they are.

M77 is a nice small galaxy in the constellation Cetus. It has a wide area of gaseous rings around it, most of which could be pulled out in this image, due to 20h of exposure. M77 is also listed in the Arp Catalogue, as Arp37.

Sh2-86 is a rather faint nebula in the constellation Vulpecula at a distance of approximately 6000 lightyear. Especially the OIII and SII signals are very faint. But during processing they could be retrieved well. Using the Hubble Palette, the final result is rather impressive with the big pillar structures in the nebula.

M39 is an open cluster in the constellation Cygnus. It consists of young bright blue stars and thanks to their characteristic positioning it is also referred to as the Pyramid cluster. Open clusters like this appear to be great targets to shoot during full moon periods.
