Since 2011, when the French amateur astrophotographer Nicolas Outters discovered Ou4, the Squid Nebula, I have wanted to photograph it, but until this summer I had not had the chance to do so.
The image covers a field of almost two degrees... Read more,
This image started out as an auxiliary image to be taken with my FSQ-106 N to get just some RGB data for the stars for my narrowband image of Sh2-129 and Ou4...
But, as stated in my previous image, the FSQ is such a nice instrument that I quickly saw that this field deserved an image of its own... Read more
The so-called Wolf-Rayet stars are a rare set of stars that exhibit very uncommon spectra showing outstanding broad emission lines of ionized helium, nitrogen or carbon. Their surface temperatures are between 20.000 K and 200.000 K higher than most other types of stars... Read more
This image started out as an auxiliary image to be taken with my FSQ-106 N to get just some RGB data for the stars for my narrowband image of WR 134....
But the FSQ is such a nice instrument that I quickly saw that this field deserved an image of its own.
Total exposure time is about 12 hours in 5 minutes sub-exposures... Read more
M78, also known as NGC2068, is a bright reflection nebula within the Orion molecular cloud complex. This wide-field image also includes the bright nebulae NGC7129, NGC2067 and NGC2064. This group of nebulae is located about 1500 light-years from Earth and many Herbig-Haro objects (energetic jets of forming stars) ... Read more
NGC7023 (also known as the Iris nebula and Caldwell 4) is a bright reflection nebula located in the constellation Cepheus. Its unusual structure of interstellar gas and dust clouds evokes the image of an iris flower. The dusty blue petals of the Iris nebula spread out over six light-years… Read more
Although NGC 1333 is catalogued as a reflection nebula located in constellation Perseus, it is in fact a more complex object that it is part of the Perseus molecular cloud. It lies approximately 1000 light years away from us and is about 15 light years across… Read more
