Starship Asterisk*

Jupiter, Europa on January 16th, 01:35-03:08ut. The moon Europa transiting across the disc on the last image (right) the moon is between the South Equatorial Belt and the South Tropical Zone edge and casting its shadow. North is at bottom.

Flaming Star Nebula.
Diffuse nebula in the constellation Auriga and owes its name to the variable star AE Aurigae, to give the impression that is burning.

I just received a new Ioptron Sky Tracker and was anxious to try it out for the first time. I am really amazed; it took me fifteen minutes to set it up and start tracking the stars. It is spot on and very accurate! This photo of Jupiter in the heart of Gemini was a stack of nine 30 second exposures taken with a Canon T2i (f/3.2 / ISO 800 / Canon 100 mm lens).

This is an image of The Rosette Nebula (Caldwell 49) that I took between the 17-18th. This is my first image of this object taken with Narrowband filters and colored with the Hubble Palette.

Some more Hubble repeats, but people seem to like them. All credit as usual, Hubble team and scientists are awesome and Judy is just the processor. Please click through the thumbnails to view the large images.

Greatpictures, geckzilla. My favorite is the NGC 604 core. What a stunner!

Integrated flux nebula (IFN) and ngc 7479 in Pegasus.
this is an image which reveal particularly IFN near ngc7479.
IFN was imaged the first time by Steve Mandel in 2004, and with scientists collaboration , the Mandel-Wilson catalog was born.
Integrated Flux Nebula is the term coined to describe a nebula illuminated by the integrated visual and UV flux of the Milky Way.
this area in Pegasus never have been imaged with integrated flux nebula.
this image image is the fruit of collaboration from JP Cales (image acquisition) and me ,M. Vanhuysse (processing), with remote setup in south of spain in particularly high and dark area (5400 ft, 22 sqm meter), with astrograph 12" f3.6/stl 11k/paramount.

Wow! I knew there was integrated flux nebulosity in Pegasus but didn't know there was any near NGC 7479!

Comet ISON on Serra Grossa

C/2012 S1 (ISON) @ 2013-11-22
Sigma 135mm f/4.5 lens + Canon EOS 350D camera (30×4 sec. at ISO 1600)

Comet ISON on November 22, 2013 one of the last images before desintegrate 6 days after during perihelion. Its brightness was at magnitude 4, although the light from dawn fill the sky already, can be perceived a tail of 2º long in shape of a narrow "V". The most brilliant object at left of image is the planet Mercury.

Venus can be seen as a small crescent in this photograph taken on January 3, 2014. If you look closely you can just make out the crescent form in this image taken with a 100mm lens as Venus was nearing inferior conjunction.

Into the Shadow of the Horsehead
http://www.rolfolsenastrophotography.com
Copyright: Rolf Wahl Olsen Link to the full resolution image (3MB): http://goo.gl/IwdfjG

The Horsehead Nebula (also known as Barnard 33) is without doubt one of the most recognized and fascinating objects in the sky. This iconic feature is formed by the sharp outline of a dark dust cloud, with a remarkable likeness to a horse's head, silhouetted against a brightly glowing patch of ionized Hydrogen (IC434) that is being energized by the hard ultraviolet radiation from nearby Sigma Orionis, a quintuplet star system lying just outside the top of the image.

I sought to process this image to show not only the traditional Horsehead silhouette but also the details of the dense dust cloud (Lynds 1630 molecular cloud) from which it emerges.
Visible in the foreground is a large looming shadow being cast by the Horsehead's tower of dust, appearing as a dark fan-shape all across the image down towards the bottom centre-left, intercepted on its left edge by the intricate bright blue reflection nebula NGC2023.
In contrast to the red emission glow, the reflection nebula is caused by light from the nebula's bright blue central stars which is being reflected off the surrounding dust.The brightest member of the central cluster is the B star HD 37903, a very young star with intense ultraviolet radiation that has carved a four light years wide cavity in the dust that we see as the reflection nebula.

Throughout the dark cloud, both in and below the Horsehead, are several small glowing reddish patches. These are the feeble lights from new stars being born in the cloud. Some of these are Herbig-Haro objects; the result of plasma jets ejected from young protostars which collide with the surrounding gas and dust and cause the glowing emission. Inside the bright blue nebula NGC2023 are also several brightly coloured wisps of emission patches, further hints of young stellar objects and the regions' overall complexity and beauty.

Very nice indeed, Rolf. I had never before seen, or noticed, that fan-shaped shadow cast by the Horsehead Nebula.
