Seantos, I like all of your images! I like your very blue and pink Orion Nebula. I like Venus and Jupiter through a Saguaro Cactus, with the Pleiades looking down on them from above. I like your star trail image too, particularly because I think I can identify some of the trails - that "cluster" of blue trails on the right must be the Alpha Persei moving cluster. Your last image is very nice too, with Orion and the Hyades and Pleiades looking like sprinkled sugar or salt on the blue night sky. Tell me, what are those trees called? They look a bit like Araucaria araucana to me. We call them "apträd", monkey trees, in Swedish!

Ann

Hi Ann! Thanks for the great feedback, it is deeply appreciated! The "trees" you're referring to are called the "Cholla Desert Cactus" or "Cylindropuntia fulgida"

Starsurfer, thanks for pointing out that it was Barry Goldpaint's who took the beautiful Milky Way image. And thanks for pointing out where the cometary globule is in your own fascinating image! I was staring at the large brown dust cloud, Sandqvist 101, and seeing the "V" in the upper part of it as a mouth. There is a dark "eye" to the upper left of the "V". The cometary globule, the structure to the left of Sandqvist 101, looked like one of the arms of the ghost to me! Hmmm - Melotte 66 - that's an interesting cluster, quite rich, and it looks old to me.

And thanks for the information about Matthias Kronberger and the MASH project.

Let me comment on a few of the new images here. Vegastar, it's always nice to see you here, photographing the sky from Paris! Here you captured brilliant Venus against a background of faint stars.

Stefano De Rosa, that's a nice image of a huge crescent Moon "smile" seen next to a sacred old building!

Petr Horalek, that's an incredibly beautiful picture of a wonderful twilight sky over a lake, with the Moon making a reflection in the still water and Venus and Jupiter flying high above.

Wolfgang Promper, those are three very nice images. I particularly like the not-so-often photographed one-armed spiral NGC 4725 and the brilliant portrait of the Orion Nebula. What perfect colors and structures, and what perfect brightness profile!

kwiechen, that's a nice wide-field image of the flocculent spiral NGC 2841.

M. Raşid Tuğral, there is a sweet sense of spring in your conjunction pictures of the Moon, Jupiter and Venus. That tree looks like it is about to open up a lot of new leaves!

Hello Ann! It's great to see how passionate you are about astronomy and your devotion to commenting on everyone's hard work!
Ann wrote:Frank Sackenheim, that's a very fine picture of the Coalsack region, particularly the largest version of it. The cluster is of course the Jewel Box. (It is quite a coincidence, isn't it, that the Coalsack is right next to the Jewel Box?) That blue star is Beta Crucis, isn't it?
Ann
You're right, the blue star is Beta Crucis. Its a beautiful coincidence that both objects appear next to to each other in the sky!

The cometary globule is the elongated structure towards the left of the image attached to the large brown dust cloud Sandqvist 101 on the right. The beautiful cluster at bottom right if Melotte 66 and the galaxy is NGC 2427. Can't see a ghost but I can see a magician in the Tarantula Nebula! :D

This image is actually by Brad Goldpaint! I agree, it is a marvellous image and can see why so many ancient civilisations had such diverse myths about the cosmos with the ghostly glow of the Milky Way serving as an ethereal almost other-worldly inspiration.
Ann wrote:Starsurfer, your picture of Kronberger 61 is very fascinating, although I must say that the colors had me stumped at first. Only when I found out that this is a two-color image, made with OIII and Ha filters, did the colors make sense to me.

Ann
This image isn't by me, it was taken with the 8 meter Gemini observatory! :D Considering that it was a major observatory image release last year, it's a mystery how it wasn't chosen for APOD. I absolutely love planetary nebulae!! But I hate it when Ha and OIII is mapped in a false colour palette. To me, Ha and OIII reveal a secret hidden universe that isn't normally visible with conventional RGB filters due to their massive wide bandpass. They are excellent at revealing more structures and details that are only visible with filters that isolate their narrow bandpass light.

Kronberger 61 is one of dozens of new planetary nebulae that were discovered by the amateur astronomer Matthias Kronberger. He is a member of a group called the Deep Sky Hunters, who specialise in finding new objects from scanning DSS plates. Many of them are currently being studied right now and they represent some of the more extreme and exotic examples ever found!

Ha and OIII are also valuable for the discovery of new planetary nebulae that are on the extremely faint end of the optical wavelength. In the past 10 years, the number of known planetary nebulae has been doubled from 1500 to 3000! More than 1000 planetary nebulae have been discovered in the AAO/UKST Ha survey of the southern sky as part of the MASH (Macquarie/AAO/Strasbourg Ha Planetary Nebula Catalogue) project, an undertaking of the Macquarie University astronomers Quentin Parker and David Frew.

There has also been a northern equivalent Ha survey called IPHAS (INT/WFC Photometric Ha Survey of the Northern Galactic Plane), which has been crucial in the discovery of many new objects. So far, only a few hundred new planetary nebulae have been discovered due to only a very small percentage of the Ha survey images being analysed. At the moment, many require spectroscopic confirmation and information about the IPHAS planetaries isn't widely available yet. However, there will be an online database later this year or next year.

Young Moon and Old Sacra
http://stefanoderosa.com/
Copyright: Stefano De Rosa The image shows the two days old young Moon setting “close” to the Sacra of San Michele (Saint Michael’s Abbey, located some 30 km from Turin, Italy). The monument, sitting high on top of Monte Pirchiriano (at some 1,000 mt), is one of the largest religious complexes in Europe, with its construction and subsequent enlargements carried out over the last 1000 years, since 983. According to legend, Hugo de Montboissier was advised by angels that the mountain would be a superb place for an abbey which was built and entrusted to five Benedictine monks.

Just a few comments on my favorite images here.

Thanks, Gilles, for posting that image of Minkowski's Object, and the interesting inset explaining it!

Reinhold, I like your Leo Triplet. The amazing long tidal tail of edge-on NGC 3628 is faintly visible, and I appreciate the bluish tint of M66, the most vigorously starforming of the three galaxies here.

Chris, your last quarter moonrise and temple of Poseidon is just amazing! The temple itself looks like a noble ruin, and the "sideways" Moon with its jagged terminator looks like a sort of ruin too, one that has perhaps just "broken off" the temple and is about to tumble off the hill of the temple of Poseidon! Amazing! I agree with geckzilla, it actually looks as if the tree below the Moon might just be "propping it up"! Just fantastic.

Alistair Symon, that's a nice image of Sharpless 290 and M67. The planetary nebula looks very beautifully colorful in your picture.

Emil Ivanov, that's a very beautiful image of fascinating spiral galaxy M77. The galaxy has an active nucleus and unusually blue outermost arms.

Rolf Geissinger, that's a handsome portrait indeed of NGC 2264, the Christmas Tree Cluster and the Cone Nebula region. Hubble's variable nebula looks good, too!

Leo Dy, that's a very fine image of the constellation Gemini, taken with simple equipment. You bring out the starry richness at the Twin's feet and the "stellar near-desert" between their feet and heads.

Frank Sackenheim, that's a very fine picture of the Coalsack region, particularly the largest version of it. The cluster is of course the Jewel Box. (It is quite a coincidence, isn't it, that the Coalsack is right next to the Jewel Box?) That blue star is Beta Crucis, isn't it?

Dieter Willasch, I like the aqua-colored filamentary supernova remnant superimposed on the blobby red emission nebulae.

Gerrit Burggraaf, your use of the Hubble palette really brings out the high level of ionization near the Trapezium cluster in Orion.

Leonardo Orazi, thank you for that very fine portrait of one of my favorite galaxies, "the jumping pig" of IC 2574! (Although the pig is upside down in this image!)

José Joaquín Pérez, I'm not altogether sure I can see a cometary globule in your picture, but I can indeed see what looks like a kiddie ghost that is smiling while it is saying "Boooh!".

José Joaquín Pérez, that's a beautiful portrait of the Milky Way arcing over zodiacal light and the conjunction between Venus and Jupiter.

Seantos, I like all of your images! I like your very blue and pink Orion Nebula. I like Venus and Jupiter through a Saguaro Cactus, with the Pleiades looking down on them from above.

A lot of people forget how visible the Great Orion Nebula is through binoculars or your basic telescope on a clear dark night.

"The Great Orion Nebula"

Image

Mid-March 2012 presents the best time to see a Venus-Jupiter conjunction in the evening for years to come. At mid-northern latitudes, these two brightest planets – Venus and Jupiter – stay out for nearly four hours after sunset. That’s about the longest period possible at these latitudes. You can’t miss these two worlds in the west as darkness falls. M45, also known as the Pleiades, is also visible right above these 2 planets along with the faint milky way on the right.

"Jupiter & Venus Trail"

"Zodiac"

In this image you can see several of the universe's phenomenons including the Zodiac Lights, March's Venus, Jupiter, and Pleiades Conjunction, and the Orion Constellation.
