Nebulae

IC410 Complex

This nebula is about 12.000 light years ago, in the constellation of Auriga. Embedded in this nebula, an open cluster can be seeb (NGC1893). The contrast between the nebula and the rich star field is impressive.

Technical data: 2011/02/05. Meade LX-200 8" at F6.6, QSI-583WSG with Astrodon RGB and H-alpha filters, guiding with the DSI Pro. The luminance layer is build with 30% of the H-alpha image. Subs are: two 10-minute through H-alpha, R and G filter, and only one 10-minute sub through the B filter (a satellite track spoiled the second one). Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

IC405, the Flaming Star Nebula

This nebula named after AE Aurigae, the hot star which dominated the field. This blue star strongly ionizes the gas with its powerfull radiation. Also it casts its intense blue light on the dust inside the nebula, which gives the whole thing this spectacular blue hue. What we see here is only a small portion of the nebula complex.

It is about 1.500 light years ago, in the constellation of Auriga.

Technical data: 2012/03/10. Meade LX-200 8" at F6.6, QSI-583WSG with Astrodon RGB and H-alpha filters, guiding with the DSI Pro. Both the luminance and the R layer are built with a synthetic "R" component which mixes H-alfa and R. Subs are: five 700-second through H-alpha, and four 500-second each through R, G, and B filter. Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

The Cone Nebula

This emission nebula is about 2.600 light years ago, in the constellation of Monoceros. It's strange shape is due to an absortion nebula in front of a light, emitting one. 

Technical data: 2012/02/11. Meade LX-200R 8" at F6.6, QSI-583WSG, thru Astrodon RGB and H-alpha filters, guiding with the Meade DSI Pro. 4 subs of 700 seconds, binned 2x2, trhu H-alpha filter, and 3, 400 seconds, binned 2x2, trhu RGB each. Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with Pixinsight.

The Tulip Nebula (Sharpless 2-101)

This emission nebula is about 6.000 light years ago, in the constellation of Cygnus. I's very close, visually, to the micro-quasar Cygnus X-1, a suspected black hole. The region surrounding this nebula is rich in Milky Way stars, which adds to the object beauty.

Technical data: 2011/10/08. Meade LX-200 8" at F6.6, QSI-583WSG with Astrodon RGB and H-alpha filters, guiding with the DSI Pro. The luminance layer is build with 50% of a sysnthetic R, composed of R and H-alpha. This synthetic R is also used instead of the normal R to form the RGB component. Subs are: 5 subs, 700-second each through H-alpha, and 3 subs, 500-second each through R, G and B. Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

Cocoon Nebula (IC5146)

This nebula is located in Cygnus, at 4,000 light years away. It is a fine imaging object, with interesting detail inside. It is surrounded by a dark nebula, which one can see looking for dark patches which hide the rich star background. It's also surrounded by faint nebulosity which created a tinny light gradient.

Technical data: 2011/09/17. Meade LX-200 8" at F6.6, QSI-583WSG with Astrodon RGB and H-alpha filters, guiding with the DSI Pro. Subs are: five 700-seconds and binned 2X2 through H-alpha, and only one 500-seconds and binned 2X2 through R, G and B filters (a problem with the anti-dew system prevented me from taking more subs!). Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

North America Nebula (NGC7000) portion

This nebula is very wide, and its gas emits under the radiation of a star. It's not clear which one is responsible for this emission, but some sources sign Deneb as the one.

Technical data: 2011/07/15. Meade LX-200 8" at F6.6, QSI-583WSG with Astrodon RGB and H-alpha filters, guiding with the DSI Pro. Subs are: five 700-seconds and binned 2X2 through H-alpha, and three 300-seconds and binned 3X3 through R, G and B filters. Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

go to the top....

Veil Nebula

This nebula is a remnant of a "recent" supernova explosion, abot 5.000 or 8.000 years ago. It is a wide-field object, with some different sections. This one is the western section, easily recognized because there is a 4-magnitude star near the center. Watch the delicate filemants and structure of this beautiful nebula.

Technical data: 2010/12/04. Meade LX-200 8" at F6.6, QSI-583WSG with Astrodon RGB and H-alpha filters, guiding with the DSI Pro. The luminance layer is build with 50% of the H-alpha image. Subs are: one 10-minute and two 5-minute for each one of the filters. Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

NGC7625 (Bubble Nebula)

This is an emission nebula in Cassiopea, and it's about 12.000 light years from here. The strong stellar wind from the hot, central star is clearing out the space around it.

Technical data: 2007/10/13. Meade LX-200R 8" at F5, Meade DSI Pro, 70 frames 30 secods each. Processed with AstroArt

A more recent picture, with improved stacking and processing, and using color filters.

Technical data: 2009/08/19. Meade LX-200R 8" at F5, Meade DSI Pro, 24Red42, 16Green60 and 17Blue60. Stacked with DeepSkyStacker, and processed with MaximDL and AstroArt.

go to the top....

NGC6888 (Crescent Nebula)

This nebula is the remnant of what was a red supergiant which lost its outter layers. Now the star, still 30 times more massive than our Sun, is very hot, and creating a very powerfull stellar wind which is pushing the nebula ahead. This star is near the end of its life, and will end up as a supernova explosion. It's 5.000 light years from here.

Technical data: 2007/09/01. Meade LX-200R 8" at F3.3, Meade DSI Pro, 155 frames 15 secods each. Processed with AstroArt, and a anti-blooming plugin.

Technical data: Meade LX-200R 8" at F3.3 thru color filters, Meade DSI Pro, 20 frames 30 seconds each Luminance, R, G and B. Processed with Astroart.

And with the new QSI! 

Technical data: Meade LX-200R 8" at F.6.6. QSI-583WSG, thru Astrodon RGB and H-alpha filters, guiding with the Meade DSI Pro. False color composition, with H-alpha as luminance (2 subs of 10 minutes each). Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

Deeper into the Crescent: Meade LX-200R 8" at F.6.6. QSI-583WSG, thru Astrodon RGB and H-alpha filters, guiding with the Meade DSI Pro. H-alpha and R blending. Subs of 600 seconds, binned 2X2 (5 subs for H-Alpha, and 3 sub s for RGB). Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

Horsehead Nebula

This is one of the most famous nebulas! In Orion, it's basically a dark nebula whose profile appears drawed in front of an emission nebula. This is the kind of deep sky object which I could see in text books when I was a child: those remarkable pictures of Monte Palomar. Now, these objects are at reach of modest amateur scopes!

Technical data: 2007/11/16. Meade LX-200R 8" at F3.3, Meade DSI Pro, 80 frames 21 secods each. Processed with AstroArt.

Technical data: 2007/12/06. Meade LX-200R 8" at F3.3, Meade DSI Pro, 44 frames 60 seconds each. Processed with AstroArt.


Ok, and this is my first attempt with the new QSI CCD. Not bad, although a lot of noise indicates that more signal was needed.

Technical data: 2012/02/11. Meade LX-200R 8" at F6.6, QSI-583WSG, thru Astrodon RGB and H-alpha filters, guiding with the Meade DSI Pro. H-alpha and R blending. Subs of 700 seconds, binned 2x2, trhu H-alpha filter, and 400 seconds, binned 2x2, trhu RGB, totalling about 2 hours and a half. Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with Pixinsight.

This is a cropped image, so that more detail of the nebula can be seen.

M1 (Crab Nebula)

This is the remnant of a supernova explosion which took place in the year 1054, from a star whcih had about 10 times the Sun's mass. Now, at its center, sits a rotating neutron star (pulsar), giving a complete turn on only 0,33 seconds!!! At 6.500 light years from here, it is one of the most studied objects in the sky.

Technical data: 2007/11/01. Meade LX-200R 8" at F5, Meade DSI Pro, 32 frames 30 secods each. Processed with AstroArt  and with an anti-blooming plugin.

go to the top....

M8 (Lagoon Nebula)

The Lagoon is a very extensive nebula, covering about 45 arcminutes X 30 arcminutes of the sky in Sagittarius. Embedded in the nebule, one can find NGC6530, and open cluster. The Lagoon is thought to be a star nursery. It lies about 5.000 light years away, in the direction of our galactic center.

Technical data: 2007/08/09. Meade LX-200R 8" at F3.3, Meade DSI Pro, 21 frames 8 secods each. Processed with AstroArt and a deconvolution filter. This was one of my first pictures, and using an altazimuthal configuration (and a very short exposure!)

Technical data: 2009/07/25. Meade LX-200R 8" at F3.3, Meade DSI Pro, 8 frames 60 secods each through filters G and B, and 8 frames of 20 seconds each through R filter. Processed with AstroArt and GIMP.

go to the top....

M17 (Swan Nebula)

Also called the Omega nebula, this object sits in the constellation of Sagittarius, and it's about 7.000 light years from us. It shines because the stars inside the nebula ionize it.

Technical data: 2007/08/09. Meade LX-200R 8" at F3.3, Meade DSI Pro, 21 frames 20 secods each. Processed with AstroArt and a deconvolution filter. This was one of my first pictures, and using an altazimuthal configuration (and a very short exposure!)

This is a more recent picture, using color filters and improved stacking and processing. And longer exposures, that allows more nebulosity to be captured!

Technical data: 2009/08/15. Meade LX-200R 8" at F3.3, Meade DSI Pro, 17Red30 9Green60 8Blue60. Stacked with DeepSkyStacker, and processed with MaximDL and AstroArt.

go to the top....

M20 (Trifid Nebula)

The Trifid is a remarkable, spectacular object! It glows because the stars that shine inside it, and  it owes its name to the three-lobe configuration seen throught the telescopes. It's in Sagittarius, and it's about 5.000 light years from us.

Technical data: 2007/08/09. Meade LX-200R 8" at F3.3, Meade DSI Pro, 50 frames 8 secods each. Processed with AstroArt and a deconvolution filter. This was one of my first pictures, and using an altazimuthal configuration (and a very short exposure!): this demonstrates the impressive brightness of the Trifid, and makes it one of the easiest objects in the sky.

Technical data: 2009/07/25. Meade LX-200R 8" at F3.3, Meade DSI Pro, 8 frames 60 seconds each, through R,G and B. Processed with AstroArt amd GIMP.

go to the top....

M27 (The Dumbbell Nebula)

This is an all-time, favorite of amateurs around the world, because of its beauty and also because it's a real easy target. The first time one visually sees it through a modest telescope, on a dark night, is unforgettable. The name comes from its shape, resembling a big Bell. The Dumbbell sits in Vulpecula constellation, and it's thought to be the product of a old, big star giving off its outer layers. It's 1.000 light years from here.

Technical data: 2007/08/31. Meade LX-200R 8" at F5, Meade DSI Pro, 10 frames 30 secods each, and using an altazimuthal configuration.. Processed with AstroArt.

Technical data: 2008/07/04. Meade LX-200R 8" at F5 thru color filters, Meade DSI Pro, a combination of 300 seconds Luminance, and 180 seconds R, G and B. Processed with Maxim DL and Astroart.




Technical data: 2007/08/04. Meade LX-200R 8" at F10, Meade DSI Pro, 75 frames, 4 seconds each. Well, this was my attempt to image with the LX native configuration, at F10, and showed to me what difficult is to frame with a bad combination of scope and CCD! Since then, I've been using a focal reducer in most of my images!


OK, and with better exposures, and improved stacking and processing this is one of my preferred pictures so far.

Technical data: 2009/08/17. Meade LX-200R 8" at F5 thru color filters, Meade DSI Pro, a combination of 12Red42 12Green60 and 10Blue60. Stacked with DeepSkyStacker, and processed with MaximDL and AstroArt.

M42 (The big Orion Nebula)

The Orion Nebula is one of the famousest objects in our sky. It is so bright that it can be seen with naked eye, looking south, in the Orion sword bell, on clear winter nights. M42 is a star nursery, and it glows because it's ionized with the hot, young stars inside. At its center, lies what it's called as Trapezium (the very brightest part of the picture), which is a "multiple star" complex of 17 stars! The Orion nebula is about 1.500 light years from us.

Technical data: 2008/12/20. Meade LX-200R 8" at F3.3, Meade DSI Pro.

go to the top....

M57 (The Ring Nebula)

In the constellation of Lyra, this remarkable planetary nebula is the result of an old star blowing off its outter layers about a thousand years ago. This shell is expanding at about 50 Kms per second. Another astonishing and very easy target, it's a must in every summer session. It's 2.000 light years from here.

Technical data: 2007/08/04. Meade LX-200R 8" at F10, Meade DSI Pro, 70 frames 4 secods each. Deconvolution filters have produced a strange star effect. Imaged with the native F10 configuration, and giving a very demanding pixel resolution combined with the DSI, it is one of the tests that convinced me about using a focal reducer!

Technical data: 2007/08/27. Meade LX-200R 8" at F3.3, Meade DSI Pro, 7 frames 42 seconds each. Processed with Astroart. Compared  with the F10 picture,  I clearly loose detail... but I gain light, stability, ... and fun!

And one of my last pictures in color. I'm quite proud about this one. The seeing was extraordinary, and the contrast I've got in the frames was very good.

Technical data: 2009/09/10. Meade LX-200R 8" at F5, Meade DSI Pro, R17X42s, G8X60s, B8X60s. Stacked with DeepSkyStacker and processed with Maxim DL. 

And here the same image but doubled in size. The seeing was so good that the image can afford this!

NGC6960 (The Veil Nebula)

In Cygnus, the Veil is the remnant of a huge supernova explosion, that ocurred about 5-10 thousand years ago. In this cataclism, a star of about 15 times the Sun's mass died. This nebula is a huge target, and appers divided up into two main sections. The whole surface is too big to be captured with my configuration, and we only see a small fraction in this picture. The Veil nebula is about 1.400 light years from us.

Technical data: 2007/08/31. Meade LX-200R 8" at F3.3, Meade DSI Pro, 23 frames, 42 seconds each.

go to the top....

M16 (The Eagle Nebula)

This nebula got famous after the Hubble pictures, called Pillars of Creation, in which it's shown how some parts of this object are nurseries of new stars. The Eagle is in the constellation of Serpens, and about 6.500 light years from us.

Technical data: 2009/08/13. Meade LX-200R 8" at F3.3, Meade DSI Pro, 17 frames Red 30 seconds each, 12 frames Green 60 seconds each and 11 frames Blue 60seconds each. Stacked with DeepSkyStacker, and processed with MaximDL ans Astroart.

Galaxies

NGC3190 galaxy group in Leo

The picture shows the galaxy group knonw as NGC3190, some 60 million light years away, in Leo.NGC3193 is the difuse elliptical near the center. NGC3190 is the beautiful spiral, near edge-on, showing the clear dust lane in its plane. NGC3187, to its right, is another spiral, with distorted arms due to the interaction with NGC3190. NGC3185 appears in the top right side of the picture, but it is not related with the group. Also, at least two other faint galaxies can be seen.

Technical data: 2011/04/09. Meade LX-200 8" at F6.6, QSI-583WSG with Astrodon RGB and Luminance filters, guiding with the DSI Pro. Subs are: four 10-minute through Luminance, and three 10-minute subs through R, G and B filters (130 minutes total). Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight. I haven't been able to completely remove the small gradient at the top of the image without affecting the faint galaxy there. Also, a satellite track shows at the left.

M33 (Pinwheel Galaxy)

This galaxy is the third most luminous one in our galaxy local group (this group contains 40 galaxies, along with our own galaxy and the Andromeda galaxy). At 2,8 million light years, it is a spiral galaxy about half the size of our Milky Way, and contains about 10 billion stars. It hosts a central black hole weighting about 3.000 solar masses.

Technical data: 2007/09/15. Meade LX-200R 8" at F3.3, Meade DSI Pro, 85 frames, 42 secods each. Processed with AstroArt.

Well, and this is the image taken with my new QSI583WSG. What a change!

Technical data: 2011/06/26. Meade LX-200R 8" at F6.6, QSI583WSG, guided with the DSI. Subs are: four 10-minute thru L filter, binned 2X2, and three 10-minute subs trhu R, G and B, binned 3X3. Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

go to the top....

M51 (Whirlpooll Galaxy)

M51 is a grand spiral, lying about 30 million light years away. What seems to be a close interaction with a small galaxy, NGC5195, is only an optical illusion, as the small companion is perhaps half million light years appart from the Whirlpool. Nevertheless it is pretty provable that the two galaxies have interacted in the past, and that interaction triggered star formation in M51, process which continues today at a rithm of 4 new stars per year. This is the same birth rate as in our galaxy, ... but M51 has 10 times less mass.

Technical data: 2008/03/17. Meade LX-200R 8" at F5, Meade DSI Pro, 21 frames, 20 secods each. Processed with AstroArt.

And this is M51 with a supernova! Imaged in Juny 2011, after some days the supernova was discovered there.

Technical data: 2011/06/26. Meade LX-200R 8" at F6.6, QSI583WSG, guided with the DSI. Subs are: four 10-minute thru L filter, binned 2X2, and three 10-minute subs trhu R, G and B, binned 3X3. Adquired with Maxim/DL, registered with DeepSkyStacker, and processed with PixInsight.

M65

This galaxy lies in Leo, and it's 35 million light years away. We see it nearly edge-on, and it shows us the dust bands near the equator. A barred-spiral galaxy, as our Milky Way, it gives us an idea of what our own galaxy looks like.

Technical data: 2008/02/09. Meade LX-200R 8" at F5, Meade DSI Pro, 26 frames, 42 secods each. Processed with AstroArt.

M101

In Ursa Major, this galaxy is face-on. It is very actively creating new stars. It lies 25 million light years away.

Technical data: 2007/08/09. Meade LX-200R 8" at F3.3, Meade DSI Pro, 72 frames, 20 secods each. Processed with AstroArt and using a hotpixel fix. It's evident a vignetting effect produced by the focal reducer, and also a gradient due to the Moon.

go to the top....

NGC891

One of my favourites galaxies! Looks impresive nearly edge-on. The dust lane, shown here as a fine black line in the equator, is actually 1.500 light years thick! This galaxy is thought to represent a quite precise image of what our galaxy looks like. It is 30 million light years away.

Technical data: 2007/10/13. Meade LX-200R 8" at F5, Meade DSI Pro, 122 frames, 30 secods each. Processed with AstroArt.

NGC7331

Thought to host a supermassive central black hole of about one billion solar masses. It's 50 million light years away. Some other galaxies can be seen in the picture, but although they appear as if they were gravitationally linked with NGC7331, they just happen to be in the same visual line from here.

Technical data: 2007/11/01. Meade LX-200R 8" at F5, Meade DSI Pro, 103 frames, 21 secods each. Processed with AstroArt.

The Sculptor Galaxy

This is a member of our galaxy local group, and it's a quite beautiful companion.

Caldwell 30

Together with this spiral, some other galaxies appear in the picture. The group is called the Deer Lick Galaxy Cluster.

Technical data: 2009/08/15. Meade LX-200R 8" at F3.3, Meade DSI, 28Red30, 18Green60 and 22Blue60. Stacked with DeepSkyStacker, and processed with MaximDL and AstroArt.

Globular and Open clusters

M13

One of the most astonishing objects, M13 is a classic target for beginners and experts alike. Never to forget the first time one sees it through the scope. It contains 600.000 stars in only 120 light years space. This object forms part of our galaxy, but it has its own orbit around us, taking half a billion years to complete it.

Technical data: 2007/08/09. Meade LX-200R 8" at F3.3, Meade DSI, 15 frames 20 secods each. Processed with AstroArt. (hey, I'm quite proud of it, because I think I got one of the best focus I can achieve with my configuration)

Technical data: 2008/07/05. Meade LX-200R 8" at F5 thru color filters, Meade DSI, 180 seconds Luminance, and 180 seconds R, G and B. Processed with MaximDL  and Astroart.




M21

This is an open cluster, just on the Milky Way in Sagittarius. This is quite a young cluster, with only 4,5 milions years.

Technical data: 2009/09/11. Meade LX-200R 8" at F3.3, Meade DSI, R4X42s G4X42s B4X42s. Stacked with DeepSkyStacker, and processed with Maxim DL.

M15

With a mass of nearly a million Suns, this globular revolves around the galactic center in about 250 million years. Recent studies hypotize that it contains a central black hole, with a mass of several thousand Suns, but this remains uncertain.

Technical data: 2007/10/27. Meade LX-200R 8" at F5, Meade DSI, 17 frames, 15 secods each. Processed with AstroArt.

And this is a more recent picture, RGB, longer exposures, and improved stacking and processing. No comparison!!!!!!

Planets and comets

Comet 17P/Holmes

This humble comet surprised the whole world at the end of 2007, displaying an astonishing show. In just a few days, it went crazy, increasing its brightness, and reaching a magnitude so that it could even be seen naked-eye depending on the visibility conditions. With the same quickness, it faded afterwards, returning to its normal, expected, brightness. What drove it to this odd behavior? 

Technical data: 2007/11/03. Meade LX-200R 8" at F5, Meade DSI, 17 frames, 1 secod each. Processed with AstroArt.

Jupiter


The biggest planet in our Solar System, it is always an interesting target: not only for it's size, but also for the spectacular colors of the upper atmosphere.

In these pictures, at F10, 3 of the four Galilean satellites can be seen. In the first picture, brightness has been exagerated so it's easy to see the moons:


This is one of my latest pictures, at F20 and through RGB color filters


And this one was framed at F10, on August, the 17th 2009.



The red spot is a "permanent" and huge strom in the planet's atmosphere. As Jupiter revolves in about 11 hours, it's very easy to capture the quick movement of the atmosphere features, as in these pictures, taken at F20 and with color filters:

And here there's one of the first pictures I took (gray-scale):

Saturn

This planet is always a jewel to see... ant to image, although I confess that it hasn't been an easy target for me so far. Here you can see one of  my best shots at F20... which cannot compare with those of Jupiter yet!
