NGC 7000North America Nebula - Cygnus Wall

The North America Nebula is an emission nebula in the constellation Cygnus.

Distance to Earth - 2,202 light years

As we are experiencing a big change in North America right now, I thought I would take a deep sky image of the North America Nebula, concentrating on the Cygnus Wall. It's only slightly bigger than the one Trump was planning to build on the north Mexico border!

I don’t think my image is quite as important as the change currently happening 'over the pond' but I thought it would be fairly topical.

This is my first image in 7 long years, as I look to immerse myself back in the world of astrophotography. I have missed the beauty and awe of this hobby, but I have not missed it's frustrations. It's a challenging and deeply technical pursuit at the best of times, with absolutely zero tolerance for mistakes. Also, having a beautiful 10 month old little girl doesn't facilitate many long cold nights, sat in the garden on my own...

This is a 7.5 hour image from 151 integrated, 180 second sub frames taken over 2 nights in my cold and slightly cloudy back garden. A 98% moon didn't help on the first night, but I'm jumping back on the steep learning curve of astrophotography and I might as well start as I mean to go on. Difficult but rewarding times ahead.

I'm very happy with this first image after many years out of the hobby and I am aiming to keep going strong. Hopefully I can get some nice captures overs the next few months, weather permitting...

There are some problems with the stars in this image that I struggled to deal with in post-processing, any constructive criticism is always welcome.

I have also turned this image in to a 'starless' version using StarNet++ which I will post separately in the near future.

Cheers everyone and clear skies!!

A wide-field shot of the Dumbbell Nebula (M27) in the constellation Vulpecula taken with a Nikon D5100 DSLR using a lens of only 102mm focal length. This image is best viewed in the Flickr light box (press the "L" key to toggle the light box and optionally click on the "View all sizes" menu item to see the image at its largest size).

 

This is a stack of eleven images that were exposed for 25 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). This relatively short exposure managed to capture some very slight evidence of the red outer edge of the nebula along with the faint bubble extending from the central dumbbell-shaped pattern.

 

See the image notes to identify a star which has a Jupiter-size planet in its orbit. It has been reported that both water vapor and organic molecules (methane) have been detected in the spectrum of this exoplanet (although the planet itself is believed to be far too hot to support life).

 

Captured on October 18, 2011 between 9:47PM and 10:05PM PDT from a moderately dark-sky location using a Nikon D5100 DSLR (ISO 2000, 25 second exposure x 11) and a 70mm-300mm AF-S G Zoom Nikkor lens at its 102mm f/4.5 position. Image stack created with DeepSkyStacker using eleven image frames combined with nine dark frames (no flats or bias). Final adjustments done in Photoshop CS3 (curves, levels, color balance and saturation, and image sharpening) with tweaks to the star size and color saturation done using ProDigital Software's Astronomy Tools.

There was plenty of cloud coming and going, eventually after spending 1 hour taking lights of 13 seconds each, I eventually got 82 lights that had no cloud.

 

Deepskystacker processed 73 of them along with 43 darks at 13 seconds each and an ISO of 12800.

The Veil Nebula in Cygnus from my backyard in Los Alamos, New Mexico.

 

I shot this with a Canon EF 70-200 f/4L on an AstroTrac mount. I've tried using the 70-200 on the AstroTrac in the past, but couldn't get the object of interest in the field of view. This time I tried something different. I put a 35mm lens on the camera, centered the nebula as best I could (which turned out to not be as centered as I would have thought). Then I switched lenses to the 70-200, without moving anything. At 70mm, the nebula was not quite in view, but I played around until it was centered, then zoomed in to 200mm.

 

Each focal length required a new focus to be able to even see the nebula, so that took a lot of extra time (and the focus is still a bit off). By the time I got the nebula centered and focused at 200mm, it was starting to get pretty close to the horizon. The tracking of the mount is off, and I should have tweaked the polar alignment a bit more, but I was running out of time (and I had already spent so much time on this tartget, I didn't want to switch to another).

 

I really need to come up with some other method for pointing longer lenses on the AstroTrac. I have a few ideas, but just need to find some time to get out in the grage and make some brackets for attaching finder scopes, etc.

 

This was also the first time I tried an Astronomik CLS EOS-clip filter, which I think did an amazing job of cutting down the light polution.

My god this is tough!

 

I was going to leave this alone, having deleted my last miserable attempt at reprocessing it, until I saw this.

 

Miku's excellent effort is half the exposure time at half the iso - that was a red rag to a bull. :)

 

So I've come up with this. Not as good as Miku's, but better (I think) than my last effort.

Very hazy skies and high clouds, it hadn't quite cleared and its come out in the processing. Found it tricky to balance the colours but think i've got it about as well as I can.

 

20x 60sec exposures stacked with DSS, 2 methods tried, stacked on comet and stars gave the more pleasing result.

After I have spent hours to watch the starry sky, I tried to realize a image of our nearest neighbor galaxy : Andromeda M31.

 

Wihtout using a tracking mount, I took 64 images (+ 20 darks) that I superimposed with DeepSkyStacker software.

 

In order to improve the clarity of the photograph, I used lightroom. But the focus is not perfect unfortunately...

Although this may, on the face of it, appear to have lost some detail, I'm happier with this. I think the previous version was a little overcooked, and I prefer the stars in this one as well. Slightly wider crop. If I get the opportunity I'd like to give this more time, but when using a zoom lens, all the time has to be in one session as any slight variation in focal length will cause DSS to throw a wobbler. :)

The Sunflower Galaxy, M63 aka NGC 5055 is in the constellation Canes Venatici. It's about 37 million light years away and is part of the M51 Group which, not surprisingly, includes M51.

 

This was an absolute pig to process. It's not hugely bright and needs a lot more than the 50 minutes I was able to give it. Still - I can cross it off the list now! :)

I could have produced a much cleaner image by dropping the ISO a stop and gathering an hour of light rather than 16 minutes, but I wanted to see how the D610 would perform when pushed. Pretty well it seems. The grainy looking grey stuff around the edges is dust that's just on the verge of visibility with such a short exposure.

 

Also the composition isn't that great.

After 20 frames I was starting to lose the feeling in my fingers, at which point I figured it was a good time to stop. So, unless it repeats its 1892 behaviour and undergoes a second outburst sometime in January, this will probably be the last image I'll post of Comet Holmes.

 

Two naked-eye comets, a total lunar eclipse, and a daylight lunar occultation of Venus: 2007 has been a pretty good year for astronomy!

 

Best viewed large.

The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter.

I got lucky when I wanted to shoot a long exposure of the milky way in Senj, Croatia: there were divers in the water with lights, adding an interesting extra element to the photo.

 

Shot with D7100, Sigma 17-50mm @ 22mm, F2.8.

ISO 1600, 15s.

 

I used Deep Sky Stacker to stack 18 light frames and 18 dark frames. Once with alignment for the stars (sigma-delta stacking) and once without alignment for the foreground (averaging).

 

The water with divers is from a single shot, because they moved from shot to shot.

Never throw your old photos away, you can always get more out of them later.

The same 20 frames as before, just different tweaks in DeepSkyStacker. Still very noisy, guess I'll add more lights when it returns in winter.

NGC7000, the North America Nebula, is located in the constellation of Cygnus. It is a very large area of emission nebula -- a cloud of superheated gas and dust -- extending some 2.5 degrees to the east of Deneb. It was discovered in the early 1890s during experiments in wide field astrophotography.

 

This image was taken through a narrowband (13nm) hydrogen-alpha filter. Details for the astro-geeks:

The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2,000 times that of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.saved with settings embedded.

Been waiting to have a crack at this - couldn't wait for the moon to go away :) Three quarters of these subs were taken with a fat moon looking on, so I'm quite pleased really.

 

Only got half the loop in here (gets a bit faint out to the right), and I did have room on the left for Sharpless 264, but that didn't put in an appearance at all - so I cropped it!

 

This is the first iteration, others may follow. Or I may wait until the moon has gone and have a crack at 4 minute subs - difficult unguided on the equator though.

 

Don't ask me where the spikes came from - I haven't a clue. :)
