Starship Asterisk*

Just another outstanding wide field mosaic from Rogelio Bernal Andreo. A flawless image, beautiful colors, unusual composition, great detail, master processing.
As I already noted in other forums, congrats Rogelio.

Thanks for the great photos and information. I do like the little moon for size comparison in the top right hand corner. Or maybe I just hadn't noticed it before, but it's excellent reference for a mug amateur. Ta for that. Marianne

My software says that Atik is Omicron Persei, the upper of the two prominent stars between the California Nebula and the Pleiades in today's APOD. Anyway, Atik is surrounded by splendidly many-colored nebulosities. That's so beautiful![/quote][quote=" http://en.wikipedia.org/wiki/Omicron_Persei"]

<<Omicron Persei (ο Per) is a star in the constellation Perseus. It has the traditional name Atik (also Ati, Al Atik, Arabic for "the shoulder"). Atik is a spectroscopic binary star consisting of a spectral type B1 giant and a type B3 dwarf orbiting each other every 4.5 days. [b][color=#FF0000]Some sources, including Starry Night (planetarium software), an atlas, and a web site attribute the name Atik to the nearby, brighter star Zeta Persei.[/color][/b] Omicron Persei is perhaps best known from the animated television series Futurama, where it is the solar system of the Omicronians- a race of [url=http://asterisk.apod.com/memberlist.php?mode=viewprofile&u=124138]giant horned toad creatures[/url].

<<Xi Persei (ξ Per) is a star in the constellation Perseus. It has the traditional name [b][color=#0000FF]Menkib (from Mankib al Thurayya: Arabic for "shoulder" [of the Pleiades])[/color][/b]. Menkib has an apparent magnitude of +4.06 and is classified as a blue giant (spectral class O7.5III). It is approximately 1800 light years from Earth. It is visually 12,700 times brighter than the Sun with absolute magnitude -5.5. If we include the ultraviolet light that emanates from Menkib its total, bolometric, luminosity is 263,000 times that of the Sun. [b][color=#FF00FF]The star has a mass of some 30 solar masses and a surface temperature of 35,000 kelvins, making it one of the hottest stars that can be seen with the naked eye.[/color][/b]>>[/quote]

Where's the Pleiades?[/quote]

Wow, nice image...

Between, as described in the caption...is the Perseus OB2 molecular cloud complex...

I could not find much on this region on the web...maybe did not look far enough....however....

Shows a different view...California Nebula is at the top...what a star field!!

RHCP reference - very nice!

Is it a big deal that it emits nuclei?

Beautiful picture; a keeper! + 8-) :clap: :yes: :thumb_up: :thumb_up:

Oh, this is such a lovely picture! So [size=130][b][color=#FF0000]c[/color][color=#FF8000]o[/color][color=#FFBF00]l[/color][color=#FFFF00]o[/color][color=#00BF00]r[/color][color=#0080FF]f[/color][color=#0040FF]u[/color][color=#0000FF]l[/color][color=#8000FF]![/color][/b][/size]

And the picture is so detailed and just fantastically widefield, like an incredible map over a huge stretch of sky.

What a great image! Welcome back, Rogelio Bernal Andreo! :D :D :D :D :D

From California to the Pleiades. Idaho what's between them, but it looks good also. :mrgreen:

[b] Explanation: [/b] An astronomical trip from the California Nebula to the Pleiades star cluster would cover just 12 degrees across planet Earth's night sky. That's equivalent to the [url=http://apod.nasa.gov/apod/ap130801.html]angular extent[/url] of 25 Full Moons, as your telescope sweeps over the borders of the constellations Perseus and Taurus.

On the left, cataloged as NGC 1499, the [url=http://apod.nasa.gov/apod/ap080307.html]California Nebula[/url] does have a familiar shape, though its coastline is actually over 60 light-years long and lies about 1,500 light-years away. The nebula's pronounced reddish glow is from hydrogen atoms ionized by luminous blue star Xi Persei seen just to its right. At the far right, the famous [url=http://apod.nasa.gov/apod/ap031227.html]Pleiades star cluster[/url] is some 400 light-years distant and around 15 light-years across. Its spectacular blue color is due to the reflection of starlight by interstellar dust. In between are hot stars of the Perseus OB2 [url=http://en.wikipedia.org/wiki/Stellar_association#Stellar_associations]association[/url] and dusty, dark nebulae along the edge of the nearby, massive [url=http://en.wikipedia.org/wiki/Perseus_molecular_cloud]Perseus molecular cloud[/url].
