Witch Head Nebula

30мар

IC 2118 (also known as Witch Head Nebula due to its shape), is an extremely faint reflection nebula believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel in Orion. It lies in the Eridanusconstellation, about 900 light-years from Earth. The nature of the dust particles, reflecting blue light better than red, is a factor in giving the Witch Head its blue color. Radio observations show substantial carbon monoxide emission throughout parts of IC 2118 an indicator of the presence of molecular clouds and star formation in the nebula. In fact candidates for pre-main sequence stars and some classic T-Tauri stars have been found deep within the nebula.

Galaxy Messier 110

29мар

Messier 110 (also known as ‘The Edward Young Star’ and NGC 205) is a dwarf elliptical galaxy that is a satellite of the Andromeda Galaxy. M110 contains some dust and hints of recent star formation, which is unusual for dwarf elliptical galaxies in general. Although Charles Messier never included the galaxy in his famous list, it was depicted by him, together with M32, on a drawing of the Andromeda galaxy; a label on the drawing indicates that Messier first observed NGC 205 on August 10, 1773. The galaxy was independently discovered by Caroline Herschel on August 27, 1783; her brother William Herschel described her discovery in 1785. The suggestion to assign the galaxy a Messier number was made by Kenneth Glyn Jones in 1967.

Lambda Cen Nebula – Minimal colour data

28мар

IC 2944, also known as the Running Chicken Nebula or the Lambda Cen Nebula, is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star Lambda Centauri. It features Bok globules, which are frequently a site of active star formation. However, no evidence for star formation has been found in any of the globules in IC 2944.

Star Trails over Natural Bridges

27мар

The iconic rock stack at Natural Bridges State Beach in Santa Cruz, CA poses serenely under a dome of star trails captured in 27 60-second exposures and combined in Photoshop.

The air was super misty and by the end of the exposure run the bulbous Nikkor 14-24mm f/2.8 lens glass was fogged with moisture, so I wasn’t expecting the shots to even be usable, but they seem no worse for wear. This is a preliminary processing; I still need to clean up many airplane light trails that litter the image, though they may not be too prominent at this low resolution.

That black “fringe” on top of the rock formation is seabirds hunkered down for the night!

Equipment: Canon EOS 6D, ISO 800, 20mm, f/2.8.

Jones-Emberson 1 (PK 164+31.1)

26мар

Jones-Emberson 1 (PK 164+31.1) is a 14th magnitude planetary nebula in the constellation Lynx at a distance of 1600 light years. It is a larger planetary with low surface brightness. The 16.8-magnitude central star is very blue white dwarf. Discovered in 1939 by R. Jones and R. Emberson, it’s “PK” designation comes from the names of Czechoslovakian astronomers Luboš Perek and Luboš Kohoutek, who in 1967 created an extensive catalog of all of the planetary nebulae known in the Milky Way as of 1964. The numbers indicate the position of the object on the sky. (“PK 164+31.1″ basically represents the planetary nebula that when using the galactic coordinate system has a galactic longitude of 164 degrees, a galactic latitude of +31 degrees, and is the first such object in the Perek-Kohoutek catalog to occupy that particular one square degree area of sky).

Partial Sun Eclipse in Rome

25мар

This composed image represents the demonstration of the Sun Eclipse in the Rome skies and the Angel with lance, lat. Vulnerasti con meum, (sculptor  Domenico Guidi) one of  the Saint Angel Bridge’s Angels.  The shadow of the lance marks the Sun disk, which isn’t eclipsed yet. The sequence  of eclipse itself was made using a telescope and than attached to a photograph of the Angel. The shots of the solar disk are made with Eos 5DMK 3 set with 1/500 and 800 Iso and optics –  Toa130 telescope, focal  1000 f / 7.7 with 2X multiplier; as a sunscreen – Baader Herschel wedge. Obviously the pictures of solar discs were resampled before being placed in the setting.
