M 76 the Little Dumbbell Nebula

Messier 76  (also known as M76, the Little Dumbbell Nebula or NGC650/651) is a planetary nebula in the constellation Perseus. 

This nebula was discovered by the French astronomer Pierre Méchain in 1780, and was included in the Charles Messier's catalogue of comet-like objects as number 76 as a double nebula without stars (for this reason, it was also catalogued as ,…Read more

LBN 251

This image shows a very crowded area in Cygnus. At the centre of the image is LBN 251, whose core is bluish due to a high concentration of ionized oxygen. 

The field shown in the first image (North is up) reveals many other nebulae such as LDN 892, LDN 891, LDN 894,…Read more

Sh2-174 Planetary Nebula

This nebula, popularly known as Valentine Rose Nebula, has both Sh2-174 and PK 120+18.1 as catalogue designations. 

It is therefore an unusual object: the fact that an object shares…Read more

Elephant's Trunk Nebula

IC 1396 is a large and fascinating gas ionized region in constellation Cepheus, 3000 light years from Earth. Among the intriguing dark structures in the interior of IC1396, the Elephant's Trunk Nebula certainly stands out.

The nebula is so named because of …Read more

M16 the Eagle Nebula and the Pillars...

It is a bit unclear for me why, in so many years of imaging, never tried M16 the Eagle Nebula. Maybe the only reason is that there are so many interesting targets and the limitation of time...

Anyway, this season I decided to image it and I devoted three nights to gather data…Read more,

Van den Bergh 152: Halpha added

Widefield image of a region of Cepheus with special interest in van den Bergh 152 (vdB 152, also known as Cederblad 201, or the Wolf's Cave Nebula), the blue reflection nebula on the right-center and Dengel-Hartl 5 (DeHt5, PK 111 +11.1) the planetary nebula on the bottom (a bit on the left), but including also many other interesting objects: LDN1217, LDN1219, B175…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...)
