Sharpless 2-224 (Sh2-224) is a supernova remnant in the constellation Auriga. Other designations for this object are SNR G166.0+4.3 and LBN 769 (The Sharpless and Lynds designations actually refer to the Ha regions within the remnant)... Read more,

NGC 1788 The Cosmic Bat

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,

Sh2-200 (HDW 2)

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,

Sh2-129 and Ou4 the Squid Nebula.

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,

Cefeus widefield with Sh2-129 and Ou4

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

Wolf - Rayet 134 (and WR 135...)

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

Widefield in Cygnus with Crescent nebula and Wolf-Rayet 134

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

M 78

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

Iris Nebula (NGC 7023)

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

NGC1333 reflection nebula in Perseus molecular cloud

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

Abell 39

Abell 39 (also known as PN A66 39 and PK 47+42.1) is the 39th entry in 1966 Abell Catalogue of Planetary Nebulae, compiled by George Abell in 1966 with data obtained from the Palomar Observatory Sky Survey (POSS).. Read more

M97 the Owl Nebula and M108 the Snowboard Galaxy

M97, the Owl nebula (also known as Messier 97 or NGC 3587) is a planetary nebula in the constellation Ursa Major.

It is one of the four planetary nebulae included in the Messier catalogue and was discovered in 1781 by the French astronomer Pierre Méchain... Read more (updated 25/04/2023)

Van den Bergh 152

Widefield image of a Cepheus region with special interest in Van den Bergh 152 (vdB 152, also known as Cederblad 201), the blue reflection nebula on the right-center and DeHt5 (PN G111.0+11.6) the planetary nebula on the bottom (a bit on the left), but including many other interesting objects: LBN538, B175, LBN528….. Read more.

Test of BlurXTerminator

I have tested BlurXTerminator with my image of NGC 2359.

I have chosen this one because last year I was very disappointed with the result I got when I processed it. In addition to the problem already mentioned about its very small rise above the horizon, the seeing ... Read more.

HFG1 & Abell 6

This field of view includes two extremely faint planetary nebulae in the constellation Cassiopeia.

In the upper part of the image, we find Heckathorn-Fesen-Gull 1 (HFG1... Read more

M1 the Crab Nebula

It was only very recently that I realized what ... I had never imaged M1 before, being the most famous, studied and imaged supernova remnant!... Read more

M27 Narrowband

M27, the Dumbbell Nebula, is a planetary nebula in the constellation Vulpecula. It is approximately 1360 light years from us...Read more 

 

LBN 576 in H alpha - Oxygen III - RGB (Reprocessed 20/05/2022)

LBN 576 (also known as Abell 85 and CTB 1) is a large supernova remnant in Cassiopeia.

It was initially catalogued by George Abell as a planetary nebula, but it soon became clear that it was an SNR. It was also recognized as a radio source and thus given the designation CTB 1... Updated 20/05/2022

Abell 31 (Sharpless 2-290): finished!

Abell 31 (Sh2 290) is a large, faint, ancient planetary nebula located in the constellation of Cancer. It is estimated to be about 2000 light-years away from us... Read more 

NGC 2359 Thor's Helmet starless

 Although I regularly use starless images  within my standard processing (to separate the image on its large scale and small scale components), I had not attempted until now to produce a final starless image (to improve the visual effect of the nebulosity)... Read more (updated 11/03/2022)
