Show full image This is a supernova remnant in the constellation Cassiopeia. Basic astronomical data on the object is sparse to find, but recent information indicates a distance of approximately 6500 ly and an age of about 10 000 years. The size is approximately 1/100 of the distance. However, data are rather uncertain. It has […]

Show full image This comet was visible in the southeast in the early morning when the image was taken. This image was acquired early on Christmas Eve. I had the telescope out all night and had a lot of frost on the rig, possibly also on the secondary mirror. The FWHM was not ideal. I

Show full image This is the NGC 6888 Crescent Nebula imaged with a dualband filter. Near this nebula is also the Soap Bubble Nebula which is designated PN G75.5+1.7. The imaging session was framed in by clouds and fog. I could have done better with focusing and the FWHM was rather large. I would have liked

Show full image This image shows the M106 galaxy. It is located in the constellation Canes Venatici, just below the Big Dippers handle. It is of the Seyfert II type, which means that it resembles a quasar. It is believed that the inner parts of the galaxy are falling into a supermassive black hole located
Show full image A very beautiful nebula that was previously unknown to me. It consists mostly of hydrogen gas which glows with a dark red color. There are also areas with carbon-rich dust. These glow with reflected light and appear as gray-blue areas in the center of the image near the bright star. The distance

Show full image The horsehead nebula is located in Orion near the bright star Alnitak in Orions belt. It is a region of black dust covering a part of the much larger red emission nebula called IC 434. This whole area is a region of heavy star formation and is part of the much larger

Show Full image This is my version of the wellknown Rosette nebula, or NGC 2237. It is located just east of Orion in constellation Monoceros at 5 000 lightyears distance and it is about 130 ly in diameter. The bright stars in and around the nebula excites the atoms in the nebula gas, and this
Show full image This is a nice target for small telescopes. The surface luminosity is rather high which makes it comparatively easy to image. It is located in Canes Venatici at a distance of about 30 million light years. It is interacting with the close companion NGC 5195. It is believed that the two galaxies

Show full image The image is based on a number of short video clips. They were taken with my QHYCCD QHY5III290 planetary camera. From a total of 80 000 frames 1 000 was selected using PIPP and 80% of them was stacked with Autostakkert. Sharpening with wavelets in Registax. Quite seriously I did not expect
