Mi amigo Rafael ha preparado tres plataformas en su finca para que aniden en ellas cigüeñas (dos sobre postes de aluminio y una sobre el depósito del agua). Espero repetir el año que viene la fotografía con los tres nidos ocupados, y saber mucho más de Marte. /Google translate/ My friend Rafael has prepared three platforms on his farm for storks nesting in them (two on aluminum poles and on the water tank). I hope to repeat next year the picture with the three occupied nests, and know much more of Mars.

Moonlight on El Capitan

Note Cassiopeia above El Capitain, and I'm pretty sure that is Polaris as the bright star in the upper left corner. In terms of apparent magnitude, the sun is 400,000 times as bright as reflected moonlight during a full moon.

NGC7239 - The Helix Nebula

This may very well be one of the more "viewed" images I have created since the three at NASM. Strangely, the nearly finished product of this image was still on my home PC when the CBS News crew came in to interview me on Sunday for the imminent MSL EDL. So while discussing the Eyes on the Solar System Simulation and the events of EDL, I showed the crew this image which at first they could not believe was mine. After quickly disabusing the crew of their errooneous thought, we continued. I was speaking as a JPL Solar System Ambassador. Here's a URL to the video.
http://dfw.cbslocal.com/video/7581151-c ... s-landing/
NGC7239 The Helix Nebula: This "Eye of God" was imaged on 25 July from Atoka, OK and 3 August, 2012.from Rockwall, TX using Astro-Tech AT-130 on SkyWatcher EQ-6 Pro at Atoka and in Rockwall Orion Sirius mount using QSI 583-WSG camera withAstro-Tech 2" field flattener with AstroDon Gen 2 I-series filters.in Atoka and AstroDon TRU Balance 5NM Ha filter in Rockwall. Ttotal image time is 5 hours consisting of 60L and 40ea. RGB at Atoka and 6x20min Ha exposures in Rockwall. Images captured, calibrated, aligned and combined in MaxIm DL with post-processing in Photoshop CS2. Copyright 2012 Max Corneau
The Helix Nebula (also known as The Eye of God, NGC 7239, or Caldwell 63) is a large planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae. The estimated distance is about 215 parsecs or 700 light-years. It resembles the Ring Nebula, whose size, age, and physical characteristics are similar to the Dumbbell Nebula, varying only in its relative proximity and the appearance from our equatorial viewing angle. The Helix has often been referred to as the Eye of God by someone on the Internet and surely when I post it to Facebook, that will become a very popular appellation.
The Helix Nebula is an example of a planetary nebula, or 'planetary' formed on axis to our view so we see it as a ring instead of a tube. The remnant central stellar core, known as a planetary nebula nucleus or PNN, is destined to become a white dwarf star. The observed glow of the central star is so energetic that it causes the previously expelled gases to brightly fluoresce and retreat in the face of stellar pressure. The Helix Nebula in the constellation of Aquarius lies about 700 light-years away, spanning about 0.8 parsec or 2.5 light-years. The Helix is rising around 11pm photographically from Rockwall and from Atoka where the trees block its view, it becomes visible near midnight. Observing this image from Atoka with my friend Tom Smith was truly a blessing. Enjoy the image. Almost forgot, because it only occupies a small field in this image and some of that is very opaque, there are countless tiny background galaxies in the image....see how many you can find.
Regards,
max
Mars - Curiosity Landing

Efrain,
many times at public outreach events I am asked why people cannot see the moonlanding sites, or the flags or the rovers we left behind when looking through my 16-inch Dob. The nominal response is that the moon is a quarter million miles away and we would need a stadium sized telescope, not degraded by Earth's atmosphere to see things of that scale on Luna. Obviously a single rover on Mars would be orders of magnitude more challenging to directly image. Your martian image taken with an SCT is really great. Do you suppose you could be more clear about how impossibly difficult it would be to directly image the MSL from Earth because the way it's depicted on your image could be seen as mighty confusing? For example, maybe do a little math and determine how many miles wide your little red dot would be if it were to scale. Otherwise, it's kind of a disservice to the public's understanding of this great event. They see your big telescope and have no concept of scale. for example, I'll bet that the little red dot on your image that distinguishes Gale Crater is at least several hundred miles across.

Signals from distant Mars
In this picture of the antenna DSS-63 with a diameter of 70m (20 floor building) is pointing the Curiosity rover 8 hours before landing on the surface of Mars (Also pictured). This antenna is located in Madrid and it is part of the Deep Space Network (DSN) property of NASA JPL. At the moment of the picture, the antenna was busy doing Ranging and Doppler measurements of the signals travelling from spacecraft in order to calculate its position. At the end of this session the calculated position is radioed back to the Curiosity so it can make its EDL using only its IMU and radar

The Sun is shagadelic, baby!
Discover Blogs | Bad Astronomy | 2012 Aug 09
The wonderful astrophotographer César Cantú takes amazing pictures of the sky, and his shots of the Sun are truly cool. On Wednesday, August 8, 2012, he took
this image of the Sun and a sunspot called Active Region 1524:
The Sun is a 1970s orange shag carpet!
Actually, César used an Hα filter, which blocks almost all the light from the Sun except for a very narrow slice of color where hydrogen emits light, and in fact this is preferentially given off by hydrogen under the sway of magnetic fields on the Sun, so this image accentuates magnetic activity. You can see lots of structure like the
sunspots and the plasma flowing along magnetic fields – especially along the Sun’s edge, where they’re called
prominences.
The Sun looks amazingly different depending on how you look at it. Far from being a featureless white disk, it actually has detail all the way down to the resolution of our best telescopes. The surface of the Sun is fiendishly complex, and the amount to understand is equally daunting. And, as usual with astronomy, with this complexity comes astonishing beauty.

Ptolemy's Cluster - Messier 7

Large image: http://www.pbase.com/rolfolsen/image/145284502/original
This image shows Ptolemy's Cluster, the famous bright open star cluster easily visible with the naked eye near the tail of Scorpius. It lies at a distance of 980 light years and has some 80 member stars within its diameter of about 25 light years. The age of these young bright stars is approximately 200 million years.
The cluster was known as a hazy patch in the sky already in antiquity and was first described by the ancient astronomer Ptolemy in 130 AD.
Image details:
Date: 31st May 2012
Exposure: LRGB: 48:24:24:24m, total 2hrs @ -28C
Telescope: 10" Serrurier Truss Newtonian f/5
Camera: QSI 683wsg with Lodestar guider
Filters: Astrodon LRGB E-Series Gen 2

Hi Max!, Thanks! This image was made days before the actual sucessful landing of Curiosity and quite impossible to do a accurate location of the landing!, The key words on my text is "REGION" or else i would be working with the MSL team
) and Disservice to the public at the contrary I just saw an image of Pic du Midi Observatory in France with a comparison image of the MGS doing exactly the same method I used with no image scale either. So this image is ONLY a general idea of its location, Clear Skies!
