A nice field of emission and reflection nebulas in Monocerous, with NGC 2264 the Christmas Tree Cluster area including the Cone Nebula on the lower edge of the main area of nebulosity. The yellowish star cluster below centre is Trumpler 5. Hubble's Variable Nebula is in the field (NGC 2261) but is very small at lower left of centre.
This is a stack of 5 x 12 and 2 x 10 minute exposures under sometimes hazy skies, with the Borg 77mm astrographic apo refractor at f/4.3 (330mm focal length) and filter-modified Canon 5D Mark II at ISO 800. Taken from Coonabarabran, NSW, Australia, March 2014.
Trifid Nebula from Montebello OSP at the end of July.
This is a selection from a larger image which includes M8 as well. Wanted to feature this picture as a contribution to the Cloudy Nights DSLR astrophoto forum competition for July 2014 for the M20 subject.
Taken with the Pentax K10D (modified and cooled) DSLR on the Stellarvue SV4 telescope. Guided with Orion SSAG on the Stellarvue SV70ED. IDAS HEUIB II filter was used along with the SSF6 flattener.
Stack of 19 subexposures of 1200 seconds each for a total of 6 hours and 20 minutes of integration over 3 nights (July 23, 29, 30). Calibrated with Maxim 5.25 with 64 bias, 9-18 darks (depending on temperature), and 24-64 flats (depending on date). Stacked in DSS with custom rectangle and 2x drizzle stacked. Processed in PixInsight.
Steps in PI were:
Crop to remove ragged edge, Masked stretch script, Histogram stretch to reset black point, Luminance masked noise reduction with the Denoise tool, Masked curves to darken and desaturate the background, and Unsharp mask on the brightest parts.
Exported to Lightroom for final touch (desaturate blue and red a little) and upload.
Note the rings around the brighter stars. The offset rings are from reflections inside the coverglass on the CCD. Because the larger image was framed to balance M8 and M20, the crop is not centered. Thus, the reflections are not centered.
I'm happy enough with this image, I'll revisit it with the whole frame and possibly tone down the blues a bit.

Pleiades (M45). Images taken in summer of 2015. Image taken with a Canon 6D through a 10" reflecting telescope. Stack of images totaling about an hour exposure. Processed with Nebulosity and Lightroom.
The Pleiades (M45) and its associated faint reflection nebulosity - as imaged tonite! I'm really pleased with this one. I've finally got the hang of my Smartguider 2. The seeing conditions were very poor and also the transparency, not to mention that M45 was also at a low altitude.
This image comprises of only 2 x 10 minute exposures @ ISO 800 with an astro-modded Canon 600D. Telescope: William Optics Megrez 90mm. Astronomik's CCD CLS Clip Filter.
The fog ruined the rest of the light frames, I intended to stack a total of 10. I shall revisit this 'little gem' and record more of its nebulosity...

The small reflection nebula, NGC 1999, surrounds the 10.4 magnitude star, V380 Orionis, located a couple of degrees south of the Sword-of-Orion. V380 Orionis is a young, hot star with 3.5 solar masses. Its light is reflecting off the gas and dust left over from its own creation to create the nebula NGC 1999. I read about NGC 1999 in Stephan O’Meara’s book Hidden Treasures where he lists this small reflection nebula as his 33rd object of interest (HT33). What intrigued me was that there was a dark cloud named Paramian-34 centered 15 arcseconds from V380 Orionis, well within the boundaries of the reflection nebula. O’Meara thought that he might be picking up the tiny dark cloud (Paramian-34) since the star appeared in his 4” refractor, at high magnification, as surrounded by a thin dark-circle. Now that I had a new target on my observational list, all I needed was a clear night. On February 8th, I star hopped from Orion’s lower sword star to V380 Orionis with little difficulty. I had to increase the magnification a bit to see the 2 arcminute Reflection Nebula and was pleasantly surprised how easy it was to see -- even from my suburban location. Increasing the magnification even further, I too saw what appeared to be a thin dark ring around the star embedded in the nebula. It was a good night to be out under the stars.

This is a very cropped version from the original image shot with a 50mm lens. A IDAS LPS-P2 light pollution filter was added to the lens. Digital Development Processing in AIP4W was used to pull the blue reflection nebula out of the background. A number of curve and level adjustments were made in Photoshop CS2 to enhance the blue.
Not the best in terms of star shape but the goal here was to see how much of the Merope Nebula I could coax from the sky fog and light polluted background. Obviously quite a bit when you filter out the street lamps. :O
just 25 minutes of data here (5 x5 mins). I took some shorter exposures but they were quite noisy. Ive concentrated on the wispy reflection nebulae so the red stars are a bit colourless.
The diffraction spikes were due to a bristle from a blower brush getting stuck on the flattener! Ive just left them in!

Rigel is the brightest star in the constellation Orion, and has about 40,000 times the luminosity of the sun. It is passing through some gas clouds that are reflecting the light from Rigel and are very faintly illuminated. The best known of these clouds is to the lower left of Rigel and is called IC 2118 or the Witch Head nebula. It may be a supernova remnant. All of these clouds are reflection nebula and glow mostly soft grey or blue with the light from Rigel, but there also appears to be just a bit of red emission nebula in the mix here and there.
The gory details for those interested: 13 shots on the unmodified Canon 50D were combined for a total of 54 minutes exposure at ISO1600 using the 85mm lens at f/2.8 with the camera riding piggyback. Guiding with a Nextar imager and PHD Guiding software. These nebula were very faint and required quite a bit of stretching in post-processing to bring them out.
Edited European Southern Observatory image of the reflection nebula IC 2631, glowing from light from the star HD 97300.
Original caption: A newly formed star lights up the surrounding cosmic clouds in this image from ESO's La Silla Observatory in Chile. Dust particles in the vast clouds that surround the star HD 97300 diffuse its light, like a car headlight in enveloping fog, and create the reflection nebula IC 2631. Although HD 97300 is in the spotlight for now, the very dust that makes it so hard to miss heralds the birth of additional, potentially scene-stealing, future stars.
The Iris Nebula (aka Caldwell 4) is a relatively bright reflection nebula in the northern constellation Cepheus.
An enormous gas and dust cloud (more than 6 light-years across) mostly blocks out the background stars in the Milky Way and might go completely unseen if it weren't for the intensely bright, blue-white star at it's center that illuminates (by reflection) the material in the dust cloud.
The stellar winds sculpt and shape the dust cloud into a form which somewhat resembles a purple iris flower.
This image was created by integrating 47 one-minute exposures taken through a 9.25" Flat-Field Corrected Schmidt-Cassegrain telescope. The secondary mirror was replaced with Starizona "Hyperstar" optical which converts the telescope to have a 525mm focal length with an effective optical ratio of f2.2. No filters were used during imaging.
The image was post-processed using PixInsight and the Power of Inverted Pixels (PIP) process was used to enhance the faint dust cloud visible against the blackness of deep space.

Another crack at the Pleiades, this time using autoguiding. Ah...autoguiding - so much easier and better than manual guiding! I was able to use the Denver Astronomical Society (DAS) dark site near Deer Trail, CO, this weekend. It is a great place complete with warming hut, loo, cement pads and electical outlets. I'd get the autoguiding going, start an exposure and then go check out the other scopes or get toasty in the warming hut for 10-20 minutes while the laptop and camera did all the work. Luxury! Also the DAS members were out in force this weekend which made things even more fun - nice guys with some giant scopes, including a 16 inch Dob with 17mm Ethos eyepiece, Joe's 16 inch Newt astrograph and some homemade scopes too.
The gory details: 9 varied shots were stacked for 95 minutes of exposure with the Canon 50D and 100-400 mm lens at ISO 1600, 300mm and f/5.6.

The Pleiades or the Seven Sisters or the Subaru Cluster in Taurus. First time imaging in a while due to weather. Also first light for the AT106 - I'm very pleased with it. The temp dropped throughout the night, so I had to refocus periodically. The Luminance is in good focus and is what saved this image. Session cut short with clouds and M45 getting lower in the sky. Not bad for under an hour though, so I'm happy!

A work in progress, this is the Witch Head Nebula (IC 2118) near Rigel. Seen over two nights of data collection at Montebello OSP.
I'm trying some different ways of gathering data to see what I can do. These are 20 minute subs at 100 ISO. 24 subs made up this stack for about 8 hours of integration.
Still calibrating with Maxim and stacking with DSS before going to PI.
What I've found is that for the setup, the temperature range doesn't seem to matter as much any more. Using a "set point" for the cooler at 0C seems to give a flat response for noise across the session. Thus, there's not as much need to keep as large of a library of darks. This is a good thing. Also the texture of the noise changed, so I'll have to figure out new settings in Atrous wavelet processing.
There are still flexure issues with the camera. I think I know where the problem is. I'll try a fix tomorrow and test it out this weekend.

Three star clusters in the constellation Taurus. The large, colorful V-shaped group around the bright orange star (Aldebaran) in the lower left is the Hyades Cluster. The Hyades Cluster is the nearest open cluster to us in space. Aldebaran is not a member of the Hyades Cluster, but is a foreground star. To the right, the tight knot of blue-white stars is the Pleiades Cluster. These young blue stars are enmeshed in a faint nebula; the starlight reflects off the grains of an interstellar dust cloud through which the star cluster is moving. The area above the line between the Hyades and the Pleiades is part of a hotbed of star formation, the Taurus-Auriga complex. Just above the star Aldebaran is a small grouping of tiny stars with the uninspiring name of NGC 1647. This cluster lies much farther away than the Hyades and Pleiades clusters, and its light is dimmed by interstellar material along the line of sight to the cluster.

Der große Orionnebel M42 (Messier 42). Der Nebel ist in klaren Winternächten bereits mit bloßem Auge erkennbar. Der Orionnebel wird von jungen Sternen im Zentrum des Nebels ionisiert und beleuchtet.
Direkt links vom Orionnebel befindet sich noch der kleinere blaue Running-Man-Nebel. Der Name Running Man entstand, weil der dunkle Mittelteil des Nebels so ähnlich aussieht wie ein laufender Mann. Alle Nebel sind Sternentstehungsgebiete und gehören zu einer größeren Wasserstoff-Molekülwolke im Sternbild Orion.

Messier 8 (lower part of the picture) got its name of Lagoon Nebula from the description made by Agnes Clerke in 1890, when she compared this object to a lagoon surrounded by bright fog. This area is a stellar nursery: in the hydrogen cloud (in red), which forms the emission nebula NGC 6523, bright new stars are formed, grouped in the open cluster NGC 6530 (a little to the left of the nebula’s center). Distance from Earth: 4-6.000 light years.
The Trifid Nebula (upper-right), or Messier 20, lies approximately 5.000 light years away. Stars are born here as well :)
A little above Trifid (and to the left) you can see the star cluster Messier 21, made up of young stars about 4.000 light years away from us.

Before we got to Allen Creek, I was afraid that I would rarely get to be by myself—when you're in bear country, technically you're supposed always to be in a gun-carrying pair, except for short periods of time or over very short distances. I had resigned myself to not having the wonderful, rich, solo walks I had in Sweden. I figured I would adapt.
But it turns out technicalities are technicalities, and we weren't really worried about bears where we were, when we were, and so I did have my walks after all. Usually I took them late at night, after the wind had died down for the day and the sky had entered its most changeable and beautiful stage.
This photo was taken on one of those walks. I had wandered a good way south of camp, toward what we called "Territory A," and I was looking down into a puddle of snow melt and moss between two giant tussocks.
Just weeks after NASA astronauts repaired the Hubble Space Telescope in December 1999, the Hubble Heritage Project snapped this picture of NGC 1999, a nebula in the constellation Orion. The Heritage astronomers, in collaboration with scientists in Texas and Ireland, used Hubble's Wide Field and Planetary Camera 2 (WFPC2) to obtain the color image. NGC 1999 is an example of a reflection nebula. Like fog around a street lamp, a reflection nebula shines only because the light from an imbedded source illuminates its dust; the nebula does not emit any visible light of its own. NGC 1999 lies close to the famous Orion Nebula, about 1,500 light-years from Earth, in a region of our Milky Way galaxy where new stars are being formed actively. NGC 1999 was discovered some two centuries ago by Sir William Herschel and his sister Caroline, and was cataloged later in the 19th century as object 1999 in the New General Catalogue. This data was collected in January 2000 by the Hubble Heritage Team with the collaboration of star-formation experts C. Robert O'Dell (Rice University), Thomas P. Ray (Dublin Institute for Advanced Study), and David Corcoran (University of Limerick).
Iris nebula is a very bright reflection nebula in Cepheus. The NGC7023 is a cluster within the nebula and the dusty cloud itself is cataloged as LBN 487. The Iris nebula is also associated with a larger dark cloud of interstellar dust.
Total integration 9x5min per channel in LRGB.
The Iris reflection nebula (NGC 7023) is located 1300 light-year away in the direction of the Cepheus constellation. It sits among a complex area of gas and dust which reflects the light from the star SAO 19158.
The Iris nebula consists of an open cluster NGC 7023 and the LBN 487 reflection nebula lit by the mag 7 star SAO 19158. It is also catalogued as Caldwell 4.

NGC 6820 and NGC 6823. NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The nebula and star cluster can be found in the middle of the Summer Triangle asterism which is formed by Vega, Deneb, and Altair. The reflection nebula and cluster are embedded in a large faint emission nebula called Sh 2-86. The whole area of nebulosity is often referred to as NGC 6820. The open star cluster NGC 6823 is about 50 light-years across and lies about 6,000 light-years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars.
This is not an easy target. It's probably too faint to image successfully from light-polluted urban skies and at this time of year, it doesn't get properly dark in the UK so we had just a few hours of twilight to image this object before the sky got too bright. In order to bring out as much of the nebula as possible, I had to stretch the histogram and increase the saturation far more than I'm normally happy doing which then meant I had to use more noise reduction than I'm comfortable with. However, after a lot of fiddling about, some of the nebula did come through so I guess we can call it a partial success.
