NGC7789 aka Caroline’s Rose… NGC 7789 is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. Her brother William Herschel included it in his catalog as H VI.30. This cluster is also known as “The White Rose” Cluster or “Caroline’s Rose” Cluster because when seen visually, the loops of stars and dark …
The Double Cluster (also known as Caldwell 14) is the common name for the naked-eye open clusters NGC 869 andNGC 884 (often designated h Persei and χ Persei, respectively), which are close together in the constellation Perseus. NGC 869 and NGC 884 both lie at a distance of 7500 light years. NGC 869 has a mass of 3700 solar masses and NGC 884 …
In 1995 the Hubble Space telescope wrote history by recording he image of the Pillars of Creation in the Eagle Nebula which is one of the most famous images ever made by Hubble. By then it was not known what disaster is waiting for the pillars to happen to them. An image taken by NASA’s Spitzer …
On Monday 17th of June I went to London to visit the Diamonds in the sky exhibition in London. At this exhibition artwork can be seen made by Roksana Ciurysek based partly on my images. At the Annoushka Jeweller store I had a meeting with Roksana and could I look at the images myself. I was …
Sun in H-alpha on 28-05-2012. An inverted solar disk is shown with surrounding proms… This image was image of the month on cloudy nights in June 2012…
Here is the final result of my M106 hubble processing. Unfortunately the F435W and F814W data were not clean enough to generate a good color image. So I decided to combine the Hubble data with groundbased data. This is comparable with what was done with the famous Carina Nebula image of Hubble where also groundbased …
Well, this was my hardest processing job until now. Combining the different hubble datasets to get equal colors was really hard. M77 was not fully covered by one dataset, so I had to combine channels of the WFPC2 with different wavelengths and tune the colors to get them to fit. But the result is in …
NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius. This nebula was given the name War and Peace Nebula by the Midcourse Space Experiment scientists because of its appearance. They said that in infrared images the bright, western part resembles a dove, while the eastern part looks like a skull. The …
Messier 106 (also known as NGC 4258) is a spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy, which means that due to x-rays and unusual emission …
Here are some images taken of Mars on the 19th of March 2012 with good seeing. Images were taken at different times to show the rotation of Mars. Clearly the Tharsis volcanos and Olympus Mons can be seen and also an indication of morning haze disappearing in the late Mars morning can be seen on …
