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’.

Crab Nebula M1

The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The nebula was observed by John Bevis in 1731.
The supernova was noted on July 4, 1054 A.D. by Chinese astronomers as a new or "guest star," and was about four times brighter than Venus, or about mag -6. According to the records, it was visible in daylight for 23 days, and 653 days to the naked eye in the night sky.
At X-ray and gamma-ray energies above 30 KeV, the Crab is generally the strongest persistent source in the sky, with measured flux extending to above 1012 eV. Located at a distance of about 6,500 light-years (2 kpc) from Earth, the nebula has a diameter of 11 ly (3.4 pc) and expands at a rate of about 1,500 kilometers per second.
At the center of the nebula lies the Crab Pulsar, a neutron star (or spinning ball of neutrons), 28-30km across,[5] which emits pulses of radiation from gamma rays to radio waves with a spin rate of 30.2 times per second. The nebula was the first astronomical object identified with a historical supernova explosion.
The cloudy remnants of SN 1054 are now known as the Crab Nebula. The nebula is also referred to as Messier 1 or M1, being the first Messier Object catalogued in 1758.

Rosette Nebula

The Rosette Nebula is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.
The cluster and nebula lie at a distance of some 5,200 light years from Earth (although estimates of the distance vary considerably) and measure roughly 130 light years in diameter. The radiation from the young stars excite the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.
It is believed that stellar winds from a group of O and B stars are exerting pressure on interstellar clouds to cause compression, followed by star formation in the nebula. This star formation is currently still ongoing.
A survey of the nebula with the Chandra X-ray Observatory in 2001 has revealed the presence of very hot, young stars at the core of the Rosette Nebula. These stars have heated the surrounding gas to a temperature in the order of 6 million kelvins causing them to emit copious amounts of X-rays.

NGC 7331 and Stephan's quintet

                                       
The spiral galaxy NGC 7331, in Pegasus, can be seen with small telescopes under dark skies as a faint fuzzy spot. It is an island universe similar to our own Galaxy (or maybe somewhat larger) and placed at a distance of 50 million light-years. NGC 7331 was discovered by Wilhelm Herschel in 1784
Stephan's Quintet in the constellation Pegasus is the first identified compact galaxy group of five galaxies about 300 million light-years away. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory. The group is the most studied of all the compact galaxy groups.
Recent infrared observations made with NASA's Spitzer Space Telescope have revealed the presence of a huge intergalactic shock wave, or "sonic boom" in the middle of Stephan's Quintet. This discovery, made by an international research team including scientists from the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg, provides a local view of what might have been going on in the early universe, when vast mergers and collisions between galaxies were commonplace.

Pickering's Triangle NGC 6979

Pickering's Triangle is part of the Cygnus Loop supernova remnant, which includes the famous Veil Nebula.
Astronomers estimate that the supernova explosion that produced the nebula occurred between 5,000 to 10,000 years ago.
Pickering’s Triangle was discovered in 1904 by Williamina Fleming of the Harvard Observatory while examining photographic plates of the area. The object was named in honor of her boss, astronomer Edward Charles Pickering, then director of the Observatory. Pickering’s Triangle goes by a number of aliases, including Pickering’s Wedge, Fleming’s Triangular Wisp, and Simeis 3-188. Current estimates place this supernova remnant at about 1800 light years from Earth.
The entire Veil Nebula complex, of which Pickering’s Triangle is but a portion has an apparent diameter of about 3° or nine full moons!

M13

M13 was discovered by Edmond Halley in 1714, and catalogued by Charles Messier on June 1, 1764.
With an apparent magnitude of 5.8, it is barely visible with the naked eye on a very clear night. Its diameter is about 23 arc minutes and it is readily viewable in small telescopes. Nearby is NGC 6207, a 12th magnitude edge-on galaxy that lies 28 arc minutes directly north east. A small galaxy, IC 4617, lies halfway between NGC 6207 and M13, north-northeast of the large globular's center.
M13 is about 145 light-years in diameter, and it is composed of several hundred thousand stars, the brightest of which is the variable starV11 with an apparent magnitude of 11.95. M13 is 25,100 light-years away from Earth.

NGC 4565

                                        
NGC 4565 is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Coma Berenices.
The 10th magnitude galaxy sits perpendicular to our own Milky Way galaxy.
It is also known as the Needle Galaxy for its narrow profile.First spotted in 1785 by Uranus' discoverer, Sir William Herschel (1738-1822), this is one of the most famous examples of an edge-on spiral galaxy.

M97:The OWL NEBULA



Owl Nebula was discovered in 1781 by Pierre Méchain, collaborator of Charles Messier, and it was incorporated into Messier's catalogue of diffuse objects with number 97. Although its surface brightness is quite low, it can be seen with amateur telescopes in dark nights. Large telescopes, or photographic techniques, are required in order to perceive the two cavities that justify its name. Only photographs reveal the surprising display of colours of M97.
The planetary nebula M97 is placed in the constellation of the Big Bear. It is very difficult to evaluate the distances to planetary nebulae and this case is not an exception. Thus, astronomical literature registers distances ranging from 1500 to 2500 light-years from Earth.
The central, dying star, is a small and hot object, around one hundred thousand centigrade degrees at the surface. The radiations from this white dwarf excite the atoms of the nebulous layers and make them shine. As other planetary nebulae, the shine of M97 comes mainly from the emissions from ionized hydrogen and oxygen atoms, what gives these objects their dominant reddish and greenish hues. But this object has, also, a considerable portion of light from the white dwarf that has been reflected by nebular particles. This mechanism makes its color bluer, and distinguishes this from other planetaries with a smaller reflection component.

Pinwheel Galaxy M101

 
The Pinwheel Galaxy (also known as Messier 101 or NGC 5457) is a face-on spiral galaxy about 27 million light-years away in the constellation Ursa Major.
It was discovered by Pierre Méchain on March 27, 1781, and he subsequently communicated his discovery to Charles Messier who verified its position and added it to the Messier Catalogue as one of the final entries.
M101 is a relatively large galaxy compared to the Milky Way. With a diameter of 170,000 light-years it is nearly twice the size of the Milky Way. It has a disk mass on the order of 100 billion solar masses, along with a small bulge of about 3 billion solar masses.

W.O FLT110 focuser upgrade


The Feather Touch FTF3025 Focuser from Starlight Instruments, is a major upgrade from the stock W.O focuser.
Replacing the original focuser on my FLT110 with the Feather Touch unit required about 5 minutes.
The fit and finish of the Feather Touch was something that had to be used to be appreciated!!!
