Welcome to my Astrophotography webisite. My name is Michele Vietri, I live in Tuscany and this is a website of deep sky astrophotography. I'm not a professional astrophotographer, the photos I've taken are the results of passion and patience. All images are Copyright © 2012-2020.

The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years from Earth in the Andromeda constellation. Also known as Messier 31, M31, or NGC 224, it is often referred to as the Great Andromeda Nebula in older texts. The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way galaxy, but not the closest galaxy overall. It gets its name from the area of the sky in which it appears, the constellation of Andromeda, which was named after the mythological princess Andromeda. The Andromeda Galaxy is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 30 other smaller galaxies. Although the largest, the Andromeda Galaxy may not be the most massive, as recent findings suggest that the Milky Way contains more dark matter and could be the most massive in the grouping (Wikipedia).
Gamma Cygni (γ Cyg) is the Bayer designation for a star in the northern constellation Cygnus, forming the intersection of an asterism of five stars called the Northern Cross. It has the traditional name Sadr (also spelled Sadir or Sador). With an apparent visual magnitude of 2.23, this is among the brighter stars visible in the night sky. Parallax measurements give a distance estimate of 1,800 light years (560 parsecs), with a 15% margin of error. The stellar classification of this star is F8 Iab, indicating that it has reached the supergiant stage of its stellar evolution. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified. Compared to the Sun this is an enormous star, with 12 times the Sun’s mass and about 150 times the Sun’s radius.It is emitting over 33,000 as much energy as the Sun, at an effective temperature of 6,100 K in its outer envelope. This temperature is what gives the star the characteristic yellow-white hue of an F-type star. Massive stars such as this consume their nuclear fuel much more rapidly than the Sun, so the estimated age of this star is only about 12 million years old (Wikipedia).
The Tulip nebula (SH2-101). This photo was taken on august 2012 by using a filter modified Canon Eos 400D with EF 135 mm lens at f/2.8 on Astrotrac. The photo is the sum of 30 frames, each of 2 minutes. Sharpless 101 (Sh2-101) is a H II region emission nebula located in the constellation Cygnus. It is sometimes also called the Tulip Nebula because it appears to resemble the outline of a tulip when imaged photographically. It was catalogued by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years (5.7×1016 km; 3.5×1016 mi) from Earth. Sh2-101, at least in the field seen from earth, is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. Cygnus X-1 is the bright star near the bottom right corner of the image presented here.
The inner region of the Milk Way. This photo was taken on august 2019 by using a filter modified Canon Eos 400D with EF 135 mm lens at f/2.8 on Astrotrac. The photo is the sum of 38 frames, each of 2 minutes. M16, the Eagle nebula, is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7000 light-years distant. A spire of gas that can be seen coming off the nebula in the northeastern part is approximately 9.5 light-years or about 90 trillion kilometers long. The cluster associated with the nebula has approximately 8100 stars, which are mostly concentrated in a gap in the molecular cloud to the north-west of the Pillars. The brightest star (HD 168076) has an apparent magnitude of +8.24, easily visible with good binoculars. It is actually a binary star formed of an O3.5V star plus an O7.5V companion. This star has a mass of roughly 80 solar masses, and a luminosity up to 1 million times that of the Sun. The cluster’s age has been estimated to be 1–2 million years. M17, the Omega nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses. The total mass of the Omega Nebula is an estimated 800 solar masses. It is considered one of the brightest and most massive star-forming regions of our galaxy. Its local geometry is similar to the Orion Nebula except that it is viewed edge-on rather than face-on.
Barnard 142-143. The “E” or “Barnard’s E” Nebula (officially designated as Barnard 142 and 143) is a pair of dark nebula in the Aquila constellation. It is a well-defined dark area on a background of Milky Way consisting of countless stars of all magnitudes. Its size is about that of the full moon, or roughly 0.5 degrees, and its distance from earth is estimated at about 2,000 light years.
NGC6940 and the Veil nebular complex. This photo was taken on august 2020 by using a filter modified Canon Eos 400D with EF 135 mm lens at f/2.8t on Astrotrac. The photo is the sum of 30 frames, each of 2 minutes. NGC6940 is a rich and large open cluster that lies approximately 2,500 light-years away and near the border between Vulpecula and Cygnus. The Veil nebular complex is what remains visible of a Milky Way star exploded about 9,000 years ago. The Veil nebular complex is physically huge, however, and even though it lies about 1,400 light-years distant, it covers over five times the size of the full Moon. The bright star on the left is Epsilon Cygni.

IC 405 and IC 410. IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula in the constellation Auriga, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0. Its celestial coordinates are RA 05h 16.2m dec +34° 28′. It surrounds the irregular variable star AE Aurigae and is located near the emission nebula IC 410, the open clusters M38 and M36, and the K-class star Iota Aurigae. The nebula measures approximately 37.0′ x 19.0′, and lies about 1,500 light-years away from Earth. It is believed that the proper motion of the central star can be traced back to the Orion’s Belt area. The nebula is about 5 light-years across.
California Nebula, Ngc 1499. The California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It can be observed with a Hβ filter (isolates the Hβ line at 486 nm) in a rich-field telescope under dark skies. It lies at a distance of about 1,000 light years from Earth. Its fluorescence is due to excitation of the Hβ line in the nebula by the nearby prodigiously energetic O7 star (Wikipedia).
