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’.

Helix Nebula_NGC 7293_Ha 5nm
The Helix Nebula, also known as The Helix, NGC 7293, is a large planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae.The estimated distance is about 215 parsecs (700 light-years). It is similar in appearance to the Cat's Eye Nebula and the Ring Nebula, whose size, age, and physical characteristics are similar to the Dumbbell Nebula, varying only in its relative proximity and the appearance from the equatorial viewing angle.

Emission Nebula NGC6820 with Open Cluster NGC6823
NGC 6820 is an emission nebula that surrounds open cluster NGC 6823 in Vulpecula, near M27, the Dumbbell Nebula. The nebula NGC 6820 is also called Sharpless catalog Sh 2-86.
The most striking feature is the trunk-like pillar of dust and gas protruding from the east side of the nebula towards the open cluster, NGC 6823 in the west. The center of the open cluster is about two million years old and is predominantly represented by many young, bright blue stars. Outer parts of the cluster intimately involving pillars of emission nebula NGC 6820, contain even younger stars. The huge pillars of gas and dust are probably formed when surrounding gas and dust is pushed and eroded away by radiation from nearby stars. Remarkable dark globules of gas and dust are also visible in the nebula, much as is seen in the better known Eagle Nebula in Serpens or the Lagoon Nebula in Sagittarius.
Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away

M63 Sunflower Galaxy
M63 was discovered by Pierre Méchain on June 14, 1779.[4] The galaxy was then listed by Charles Messier as object 63 in the Messier Catalogue.
In the mid-19th century, Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.[4]
In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms of M63.

IC 1795 SHO
IC 1795 is an emission nebula located about 6,000 light-years away in the constellation Cassiopeia.
The dominant central star of IC 1795 is a blue dwarf on the main sequence. In addition there are three other stars of class O and B with ages between 3 and 5 million years. This being an age intermediate to the 6 to 20 million years of the shell structure that encloses the complex. The region is one of the sites most studied (besides Orion) for the formation of massive stars. This area is more dense and rich in H II. It is home to, and hides, a group of young blue stars, with their radiation ionizing the residual gas clouds. (WIKI).

The Cave Nebula
The Cave Nebula ( Sharpless 2-155, Caldwell 9) is part of an extensive region of ionized hydrogen gas region. Sharpless 2-155 is a dim and very diffuse nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus and associated with the Cepheus B giant molecular cloud, laying at a distance of about 2800 light-years. Part of the cloud is illuminated by a pack of hot, young stars known as the Cepheus OB3 association.

Cave Nebula , the wild beauty of black and white
S 155, also known as the Cave Nebula, Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus.
Visually it is a difficult object, but with adequate exposure, makes a striking image. The nebula gets its name Cave Nebula from the dark lane at the eastern side abutting the brightest curve of emission nebulosity which gives the appearance of a deep cave when seen through a telescope visually.

M20 Trifid Nebula in narrowband
The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764.[3] Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.

Photographic shots were completed in the period from 14 June to 6 August and needed a total of 7 nights.
Unfortunately, in all the shots I had problem with passing clouds and high humidity .
