Messier 48 is an open star cluster in the constellation Hydra, the Water Snake. The cluster is situated approximately 1,500 light-years from Earth, making it one of the clusters closest to our solar system. M48 contains roughly 80 stars, most of which are young, hot, blue-white main-sequence stars.

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.

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.

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.

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.

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.

M56 is a globular cluster in the constellation Lyra. Clusters are always a bit challenging when it comes to resolving the stars in the center. Careful stretching of both the Luminance and RGB images was key in creating the required resolution.

M10 is a globular cluster in the constellation Ophiuchus. During processing special attention was directed towards fully resolving the stars, also in the center, while maintaining accurate colours.

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.

M16 is also known as the Eagle Nebula, but the central part of this nebula is made even more popular by the Hubble Telescope, and is nick-named the pillars of creation. Here in a narrowband version with a total of almost 40h of exposure.

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.

M4 is a globular cluster in the constellation Scorpius. It is located at a distance of 50,000 light years from Earth. During processing some interesting green stars stood out which appear to be RR Lyrae variable stars, often found in clusters. The intense green colour is an artefact of the way broadband images like these are taken.

M102 is a small galaxy n the constellation Draco. It is an edge on galaxy with the characteristic dust lane through the middle. It is located at a distance of 50,000 light years from Earth.

M61 is a beautiful ‘heads on’ spiral galaxy in the constellation Virgo, as part of the Virgo cluster. This particular image is shot in LRGB, but a comparison is made between LRGB and RGB processing as well.

M64 is also known as the Black Eye Galaxy, because of its characteristic detailed center in an otherwise a smooth and amorphous looking galaxy. Other nicknames are ‘evil eye’ and ‘sleeping beauty’ galaxy. This was an old set of data that had still not be processed.
