Every day our eyes catch the light of our memories – time spent with family, the journey to work, a special holiday, a beautiful sunset or a dark starlit night. Each image captured is a picture drawn in light – a photograph: only to be lost in our minds or forever forgotten. Nearly two hundred years ago a small group of amateur scientists achieved what had eluded mankind for centuries – the ability to capture a permanent record of an image seen by their own eyes – a moment in time frozen onto a surface. They had discovered Photography. They were the ‘Catchers of the Light’.

Via Lactea Observatory


View of the interior

Via Lactea Observatory


Almost 18 years ago,i embarked on a very special, difficult and demanding journey in the world of astronomy and especially in astrophotography.
Through the light pollution of Athens, the whole venture seemed almost impossible.

Watching the first shadows of nebulae and galaxies appearing on the computer screen, the pictures of planets with their moons floating into space and the spectacular formations of craters and canyons of our moon, i realized that this is was makes me feel complete, that this is what I love doing.
After long hours of studying and investing a lot of time and money, i believe that i have managed to have a decent course in the field of astrophotography. The only problem that was holding me behind was the lack of a permanent observatory.

Completely by chance i had the opportunity to meet two lovely people , Kostas and Spyros Tsekas. Without their voluntary offer, i would have never managed to full fill my dream and have my own observatory today.I would also like to thank all my friends, relatives and fellow villagers that helped me complete the observatory.
And of course I would like to thank my wife Alice that without her encouragement and understanding I wouldn't even have dreamed of turning my dream into reality.

The Observatory is located in Kristallopigi Paramithias in Thesprotia , where I have settled permanently with my family the last two years. The purpose of the observatory is the dissemination of amateur astronomy in the province of Epirus, through seminars and night sky watching.

Good luck to all with clear skies

NGC 7635: THE BUBBLE NEBULA


NGC 7635, also called the Bubble Nebula and Sharpless 162, is a H II region[2] emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7[2] magnitude young central star, the 15 ± 5 M☉[4] SAO 20575 (BD+60 2522).[7] The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.[7] It was discovered in 1787 by Friedrich Wilhelm Herschel.[6] The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses.

The Elephant's Trunk nebula is a concentration of interstellar gas and dust in the star cluster IC 1396 – an ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth.[1] The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star that is just to the west of IC 1396A.The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.

The Elephant's Trunk nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.

The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk nebula. This pressure has triggered the current generation of protostars.[2]

Melotte 15 in IC1805 reprocessed


The bright open star cluster, in this image is known as Melotte 15 after its discoverer, Philibert Jacques Melotte (1880-1961). Melotte 15 is embedded within and illuminates the central portion of the much larger glowing nebula identified as IC 1805.

The Heart Nebula, IC 1805, Sh2-190, lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing gas and darker dust lanes. The nebula is formed by plasma of ionized hydrogen and free electrons.

The interesting structure in the right of the image is a giant area of hydrogen gas that is caused to glow by the intense ultraviolet radiation from the massive stars of the Melotte 15 star cluster.
Dust and gas clouds are eroded by the pressure of the intense radiation.

The Melotte 15 star cluster is estimated to be 7,500 light years away from Earth.
