Shooting conditions were dry and dusty on the ground, very clear dark skies, a bit of wind and mild to no seeing.
This time I have done the preprocessing and editing with PixInsight 1.8, using one of many great tutorials out there. Final editing done with DxO OpticsPro 11, I might have "pushed" a bit too much and brought the noise and some dark issues out ...
If I have the patience tomorrow, I'll repeat the operation with a mosaic I shot of Orion a few nights after this photo. The conditions were not as good and Orion was getting close to Christchurch's light halo, so yeah ... annoying editing ahead ... it might take a while before you see said mosaic ... ;-)
The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. The Lagoon Nebula is estimated to be between 4,000–6,000 light-years away from the Earth. In the sky of Earth, it spans 90' by 40', which translates to an actual dimension of 110 by 50 light years. Like many nebulae, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296. It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Engraved Hourglass Nebula in the constellation of Musca. In 2006, four Herbig–Haro objects were detected within the Hourglass, providing direct evidence of active star formation by accretion within it.

Better known as the Jellyfish Nebula.
IC 443 can be found in the constellation of Gemini.
The Jellyfish nebula is a supernova remnant some 5,000 light years away from us. I have captured this not to long ago, but this time I didn't use the reducer and I had the pleasure of the dark sky of kielder

De SkySafari Plus: La nebulosa planetaria Sh2-274, conocida también como nebulosa Medusa, fue descubierta en 1955. Se estima que tiene unos 4 años luz de diámetro y que está a unos 1500 años luz de distancia de la tierra. Es irregular, con forma de media luna.
Una nebulosa planetaria representa la etapa final en la evolución de las estrellas de baja masa, similares al sol, durante el paso de gigantes rojas a enanas blancas. La forma de media luna de la nebulosa se asocia a la radiación ultravioleta emitida por la estrella ubicada en el medio.
Hacia la parte inferior derecha de la nebulosa puede verse el cúmulo abierto de estrellas NGC2395, que se estima tiene 45 estrellas visibles.
También pueden verse en toda la imagen 58 galaxias del catálogo PGC, tan lejanas, que aparecen como puntos.

Description
First image captured with the new dual rig configuration.
More than 56 hours of integration time. (Usually I am integrating 25 hours.. now dual rig :D is working ).
NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575.
The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. (Desc creditcs: Wikipedia)

La nebulosa de la Laguna (también conocida como objeto Messier 8, Messier 8, M8 o NGC 6523), es una nebulosa de emisión (concretamente se trata de una Región H II) situada en la constelación de Sagitario. Está, aproximadamente, a una distancia de 5.000 años luz.
En la porción más brillante de la nebulosa se halla una estructura conocida cómo El reloj de arena, en la que se está produciendo una intensa actividad de formación de estrellas.
La nebulosa Trífida (también conocida como Messier 20 y NGC 6514) es una región H II en la constelación de Sagitario. El nombre de la nebulosa significa "dividido en tres lóbulos", dado que la característica sobresaliente es el aspecto de tres lóbulos brillantes separados por oscuras líneas de polvo.
La nebulosa Trífida, que es una nebulosa tanto de emisión como de reflexión, tiene un brillo aparente de 6.3 magnitudes. La nebulosa está relativamente cercana, a unos 1700 pársecs, algo así como 5500 años luz.
Su edad estimada es de 300 000 años, lo que la convierte en una zona de formación estelar extremadamente joven.

A full moon and a series of winter storms meant this was very hard going and perhaps the longest it has even taken me to finish an image!

About M42, the Great Nebula in Orion:
M42 (NGC 1976) is a diffuse nebula situated in the Milky Way Galaxy, 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 from Earth, and is the closest region of massive star formation.
Why I like to "play around" with scientific data:
This Feynman quote sums it up...
"Feynman, that's pretty interesting, but what's the importance of it? Why are you doing it?'' ``Hah!'' I say. ``There's no importance whatsoever. I'm just doing it for the fun of it.'' - "Surely you're joking, Mr. Feynman'', by Richard P Feynman.

Here we have a look at the rarely seen Cederblad 30 reflection nebula and LBN 768 - This has been, by a long way, my most difficult target to date. I shot over 200 lum frames of which only 72 could be used due to background being high (net effect of altitude and general seeing conditions). Only for a brief period was the darkness suitable for shooting this image in the UK. To add to the complications even when the data was acquired it was extremely difficult to process. With 72 subs the data was relatively clean but very weak still. Overall it is probably a little softer than i would like but the data breaks down very rapidly when pushed any further. Or to put it another was I exercised artistic license to present the best version I could where required.
Not a target for the feint hearted and ideally one only for very dark sky locations. All that said it was fun to process and the challenges it presented forced me to find a few more tricks to get it to this state.
Hope you like.
Wikipedia says.....er, nothing actually; more rare than i thought!

This brightening comet is an easy target in the predawn skies with a telephoto lens of 200 mm or longer and exposures of 30 seconds or longer at an ISO of 1600 or greater (clock driven of course). Because I use a DX dSLR, the cropping factor brings the 180mm lens to ~270mm.
The inverted color image is shown to better detail the faint ion trail. The dust tail surrounding the comet's nucleus has noticeably grown and brightened during the past few days. It is still about 8th magnitude with the ion tail ~1.5 degrees long.
Tech specs: Nikon d7100, 77x60s, Nikkor 180mm @ f/5, iso 6400, cropped, Orion Sirius EQ Mount, PixInsight and Photoshop. Movement of comet is about 47 arcs / hour (~0.6 degs / day) on 24 Dec.
Probably best to keep integration time to less than 30 minutes for now in order to avoid comet motion against the fixed stars. In a month, as the comet approaches the earth, its motions will be obvious in just 5 minutes! The moon is approx 1800 arcs (0.5 degree) for comparison.

A widefield LRGB and SHO (SII+Ha+OIII) Narrowband image of the Bubble and Lobster Claw Nebula. The Bubble Nebula is also know as NGC 7635, Sharpless 162, or Caldwell 11 (a H II region emission nebula) in the constellation Cassiopeia. It lies close to the open star cluster Messier 52.
Also take a look at a closer view of the Bubble Nebula.
The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575 (BD+60°2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.
The Lobster Claw Nebula (Sharpless 157), is a bright emission nebula, and is clearly visible at the bottom right.

My latest capture of M42, the Orion nebula. This is considered as an easy target but it is also very easy to overexpose the core. I had to combine exposures from different duration to get the details in the core and still show all the details in the dust surrounding it. I am quite pleased with the result.
I will still certainly try again next year, like the last four years. Every time, I manage to improve on the last one.
