NGC 1788 is a reflection nebula located in a corner of the constellation Orion and was first described by William Herschel, who included it in the New General Catalogue (NGC).
As a reflection nebula, it is illuminated by young stars nesting in its core... Read more,
Sharpless 200 (Sh2-200) is a planetary nebula visible in the constellation Cassiopeia.
This nebula was first discovered by the American astronomer Stewart Sharpless, who included it in the second edition of his catalogue of H II regions (1959) as Sh2-200... Read more,
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
