NGC7662 // The Blue Snowball Nebula

by stargazer Email

//////////////////////////////////////////// OPiNiON & FACTS /.

this is an image of NGC7662, the blue snowball nebula. it was, with a visual
magnitude of 8.3, pretty easy to find, even though seeing was bad on that evening.
this planetary nebula has a variable star in its center and is located in andromeda,
about 5000 lightyears away with a radius of 0,8 lightyears. There you go again:

M33 // The Triangulum Galaxy

by stargazer Email

//////////////////////////////////////////// OPiNiON & FACTS /.

m33, also called the triangulum galaxy, is a spiral galaxy about 3 million lightyears
away in the constellation triangulum. its the third largest galaxy in the local group,
a group of galaxies that also contains the milky way and the andromeda galaxy and
it may be a gravitationally bound companion of the andromeda galaxy.
m33 has an apparent magnitude of 6.2. Heres the image i made:

M27 // The Dumbbell Nebula

by stargazer Email

//////////////////////////////////////////// OPiNiON & FACTS /.

this is another very famous, 1250 lightyear distant nebula and also the first object
of that type that has been discovered. the dumbell nebula has a visual magnitude of
about 7.4 and features an extremely hot blueish dwarf (85,000K) at its center. the
central star is quite bright at mag 13.5. the nebula would possibly look like a ring
viewed from a different angle (similar to m57, captured earlier). pretty cool imo.

M13 // Hercules Globular Cluster

by stargazer Email

//////////////////////////////////////////// OPiNiON & FACTS /.

another very interesting and bright object, m13, also called the hercules globular
cluster, discovered by edmond halley in 1714, and catalogued by charles messier
on June 1, 1764. m13 is about 25.000 lightyears away and has a radius of 145ly.
m13 features several hundred thousand stars. the arecibo message of 1974,
designed to communicate the existence of human life to extraterrestrials,
was transmitted into the direction of m13. heres my shot into its direction:

M31 // The Great Andromeda (Nebula) Galaxy

by stargazer Email

//////////////////////////////////////////// OPiNiON & FACTS /.

yet another very famous deepsky object, the great andromeda galaxy, m31 is
a spiral galaxy about 2.5 million lightyears away in the constellation andromeda.
it is in a moonless night visible to the naked eye. andromeda is the largest galaxy
of the local group, which consists of the andromeda, milky way, the triangulum,
and about 30 other galaxies. the 2006 observations by the spitzer space telescope
revealed that M31 contains one trillion stars, greatly exceeding the number
of stars in our own galaxy, the milky way. heres the pic i made:

M11 // Open Cluster

by stargazer Email

//////////////////////////////////////////// OPiNiON & FACTS /.

the wild duck cluster was discovered by gottfried kirch in 1681. charles messier
included it in his catalogue in 1764. m11 is one of the richest and most compact of
the known open clusters, containing about 2900 stars. its age has been estimated
to about 220 million years. Its name derives from the brighter stars forming a
triangle which could represent a flying flock of ducks. here is my image:

M57 // The Ring Nebula

by stargazer Email

//////////////////////////////////////////// OPiNiON & FACTS /.

yea, way more interesting... the ring nebula, m57, let the deepsky madness begin!
m57 is one of the most famous examples of the deepsky objects called planetary
nebulae,
often abbreviated by astronomers as simply planetaries or pn. the nebula
is located 2,300 lightyears away in the constellation lyra, south of its brightest star
vega and has a visual magnitude of 8.8. m57 is illuminated by a central white dwarf
or planetary nebula nucleus (pnn) of 15.75v visual magnitude
