This is one of the most beautiful and distinctive nebulae in our galactic neighbourhood.

The eye-catching Bubble Nebula is designated as NGC 7635, Sharpless 162 and Caldwell 11 and lies close to the direction of the open cluster Messier 52.

It is 7 light-years across – about 1.5 times the distance from our Sun to its nearest star, Alpha Centauri and resides 7100 light years from Earth in north-western Cassiopeia close to the border with Cepheus.

The 8.7 magnitude seething star forming this nebula (BD+60°2522) is 45 times more massive than our Sun. Gas on the star gets so hot that it escapes away into space as a stellar wind moving at almost 7 million km/h.

As the surface of the bubble's shell expands outward, it collides with dense regions of cold gas on one side of the bubble. This asymmetry makes the star appear dramatically off-center from the bubble, with its location in the 10 o'clock position in this image.

NOTE: This is a pseudo-narrowband image. I tried with post-processing to give the impression of using Ha, OIII and SII filters. The original version shows only red nebulosity (hudrogen). It was really a persistent and painful struggle in Photoshop :)

I went for 15s exposures (at the fixed f/8 aperture) and ISO 6400. In total 37 frames were used for a total exposure time of 9m 15s, along with 19 dark frames.

Images were stacked with DeepSkyStacker and with final processing in Photoshop to remove vignetting.

The Orion nebula is often referred to as a stellar nursery, a place where new stars are being formed out of collapsing gas clouds.

It’s nearly four months since I captured this. Where did that time go? Imaged back on the 21st of August, this shot of the Milky Way’s galactic core region includes quite a few interesting features.

The “Dark Horse” nebula is one of the most prominent parts of the shot, although down here in the Southern Hemisphere it’s more often known as the “Galactic Kiwi” due to its resemblance to the national bird of New Zealand. Grouped down at the bottom of the frame is the bright orange supergiant star Antares, with Mars to the lower right of that and Saturn across further to the right. In the same area as Antares is the Rho Ophiuchi cloud complex, a star-forming region of space. You can see some of the yellow and blue gas clouds in the photo.

Like most Milky Way fanatics I’m missing this part of the sky since it’s obscured by the sun at this time. In a few more months it will be back again and us addicts will get our longed-for fix.

This is a stacked image created from 13 “light" shots of the same region, 7 “dark" shots at the same settings as the original but with the lens cap on, plus 12 “bias” frames. Stacking reduces the digital noise of the overall image and helps to bring out a bit more detail than a single shot would. The 13 frames were captured with Canon EOS 6D, Canon 50mm @ f/2.8, 6 sec @ ISO 6400.

The North American Nebula next to the bright star Deneb in Cygnus taken with a hydrogen alpha astro modified Canon 5D MKII dslr camera using a Rokinon 135mm f/2 telephoto lens. 30 one minute images were combined to create the picture using DeepSkyStacker, Adobe Lightroom, and Gimp.

Veil nebula

The Veil Nebula complex is huge, covering about 7 moon widths on the sky, so I can’t get it all into one image. This image shows NGC6960 (sometimes called “The Witch’s Broom”), Pickering’s triangle, and NGC6979. All of these objects are part of a supernova remnant.

The supernova that created the Veil Nebula happened between 5000-8000 years ago and the nebula has been expanding ever since. The glowing gas is mostly hydrogen and sulphur (red) and oxygen (teal) whose atoms are being excited by the pressure waves created by the massive supernova explosion. The progenitor star whose explosion created this object was about 1,470 light years away.

Took the same image data I used for the full Orion's Sword image and reprocessed it with an AOI around the Orion Nebula, applying a 3x drizzle. Came out pretty well I think! The star trailing is more apparent at this zoom level, but still tolerable. The drizzle algorithm also successfully enhanced edge detail compared to just zooming in a bunch on the larger image.

The main difference of processing it this way was being able to more finely tune the luminance curve and color treatment for this object/region in particular, as not only did I not have to worry about the other regions of the image, but I could also see the fine detail much better!

Interestingly, this image is not particularly inferior to the one I got through a telescope recently. It is much better in some ways in fact!

My Sony A7S was recently defiltrated and I wanted to test it on a classic object from the night sky, the Orion constellation. I have three lenses (Samyang F1.4/24mm, Zeiss Loxia 2/50mm, Samyang F2/135mm) for astrophotography. I use iOptron SkyTracker Pro but I do not know enough how to do polar alignment so I limit myself to 10s subs for 135mm lens. Here is the result with only 4 min exposure.

My first guided image! :) The Crescent Nebula in Cygnus, a mere 5K light years away.

Bought a modded Quickcam Pro4000, with the adaptor to fit it to the SW 9x50 finder scope, from Badgers/Anton on SGL. Then did the EQ5 handset mod using the kit from Shoestring Astronomy, downloaded PHD and voila. Total cost £90 - can't be bad :) Not perfect of course, but then it was never going to be with an EQ5 and rubbish motors. There was some evidence of wispy bits around this, but it looked more like discolouration, so I took it out - probably expecting too much :)

I used the software DeepSkyStacker in order to superimpose 30 standard photos + 10 darks + 10 offsets.

On one hand , we can see that the noise has been decreasing and the contrast is higher but on the other hand the star trails have increased and only the center is sharp :-/

That is a black point of this software.

NGC 2022 is a planetary nebula in the constellation of Orion, located at a distance of 8210 light-years from the Sun.

NGC 2022 is a vast orb of gas in space, cast off by an aging star. The star is visible in the orb's center, shining through the gases it formerly held onto for most of its stellar life. When stars like the Sun grow advanced in age, they expand and glow red. These so-called red giants then begin to lose their outer layers of material into space. More than half of such a star's mass can be shed in this manner, forming a shell of surrounding gas. At the same time, the star's core shrinks and grows hotter, emitting ultraviolet light that causes the expelled gases to glow. This type of object is called, somewhat confusingly, a planetary nebula, though it has nothing to do with planets. The name derives from the rounded, planet-like appearance of these objects in early telescopes. (REF: science.nasa.gov/missions/hubble/hubbles-portrait-of-star...)

Had some issues with DSS 3.2.2, but 3.3.3 beta 51 and I got along a lot better. This is my first attempt at stacking RAW images. This is a total of 11 RAW files that represent a total of 6 minutes of integrated exposure time. The Pentax K-5ii was set at ISO 800 for all exposures and these are camera-on-tripod subs, "guided" only by the Pentax O-GPS1 unit stuck in the hot shoe, which moves the camera's sensor to compensate for the turning of the earth. The longest sub-exposure was 45 seconds.
