De SkySafari Plus y hubblesite.org: la nebulosa “burbuja” fue descubierta en 1787 por el astrónomo Británico William Hershell está a unos 11.000 años luz y del sistema solar y fue creada por un fuerte viento estelar de la estrella central masiva y joven (unas 45 masas solares) sobre el material denso en la nube molecular circundante. Tiene unos 7 años luz de diámetro.
Por su parte, la nebulosa Sharpless 2-157 (Sh2-157) es una nebulosa brillante a 43.000 años luz del sistema solar. Quiere decir que es unos 32.000 años luz más distante que la “burbuja”.
En la imagen además se ven también las nebulosas Sh2-158, Sh2-159, Sh2-161 y el cúmulo de estrellas NGC7510 que tiene unos 20 años luz de diámetro.

Decided to play with these images from October 2015 (flic.kr/p/yJxQ74) on PixInsight, see if I could get more out of it without feeling I have pushed too far. Not sure I succeeded on highlights or resolution vs. wavelet noise reduction, but at least it kept me busy a few hours ...

First time using my ZWO autoguiding mini scope and camera, and decided to test it on an easy bright target near the celestial equator.
It performed okay, the images were half decent and I processed them in PixInsight to an extent which makes no sense in regards to how few shots I got and the kind of object ... but it was good practice. ;-)

I also have 6 shots (300" @ F10 and 3200ISO) taken with a 645nm infrared filter, but the lack of resolution and noise messes up the final image if I add it to the red layer. May be I should re-process these infrared images differently ...
A look at the new Ektachrome 100 on an astronomy target.
Tracking has some issues. This indicates problems that will need to be resolved before trying a deeper exposure.
The good news is that this film shows strong sensitivity to Ha. The reflection nebula of the Trifid shows that the blue sensitivity is lacking. This could also be from the use of the light pollution filter.

IC 2177 is a region of nebulosity that lies along the border between the constellations Monoceros and Canis Major. The region is often referred to as the Seagull Nebula, and includes a larger nebulous region as well and open clusters NGC 2335 and NGC 2343 and a small reflection nebula named NGC 2327 (in the wing of the Seagull). The open cluster Messier 50 (M50 or NGC 2323) can be seen in the upper left corner.

These two objects are part of the same emission nebula that is bisected by dust into a fanciful representation of the North American continent and a pelican (right center).
During the late summer and early fall of the northern hemisphere these objects appear almost directly overhead in the night sky near to the bright star Deneb in the constellation Cygnus the Swan. Some claim that under very dark skies the North America nebula can be seen with the unaided eye (i.e. using no telescope or binoculars), but I've always believed that what people are actually seeing is the background starlight of the Milky Way that is outlined by the intervening dust.
Photographed in hydrogen alpha light using a Nikkor 105mm Ai-S lens at f/2.8 and a ZWO ASI174MM camera (just under four hours of exposure, 116 x 2m). Tracked with a Celestron AVX mount (unguided).

NGC 6742 (also known as Abell 50) is a planetary nebula in the constellation Draco. Its apparent size is 0.553′. Although the nebula’s magnitude — 13.4 — implies that it’s quite faint, the surface brightness is high enough for you to easily view it through a medium sized telescope. In the closeup view you can start to see some structure.

i think this is kind of weak sauce here. i've seen many other people with (Ha:OIII:OIII) combos for this object, so i thought i'd try it. however, i found that i got reasonable Ha subs with relatively short exposures (420s) but the OIII subs here are 4x1100s and still there's pretty much nothing there. as a result a lot of the stars are red since there's no data in the G,B channels for them.
i probably should have just done Ha(Ha+R:G:B)... but at this point i've spent a lot of $$ and maybe it's good money after bad? or maybe i should just start over. or do more research before i schedule time :)

M27 Dumbbell nebula is a bright nebula of the planetary nebula type in the constellation Vulpecula.
It is one of the first planetary nebulae to be discovered, by Charles Messier in 1764 and is called Dumbbell nebula because of its shape, resembling a dumbbell with two bright lobes and a narrower waist. The nebula is the result of an old star that has released its outer layers in a glowing display of colour.
The nebula is about 1300 light-years away from Earth and is six light-years in diameter.
This planetary nebula is located right on the border of Taurus and Perseus. It is cataloged as NGC 1514 and is also known as the Crystal Ball Nebula. The magnitude, depending on the source, is listed at 10.9.

Not a new image I'm afraid but a re-process of some files from December 2011.
This is a mixture of an RBG image with layers of Hydrogen Alpha applied to the red channel and again as a Luminance layer - mostly done in photoshop after integrating the images in Pixinsight. I also used Dave Smith's method of making a protection layer for the stars in CS5 from here -
www.youtube.com/watch?v=pVTSUppcMs8&feature=plcp
This came in useful when applying the Ha data (to stop those cyan halo stars) and when sharpening up the image, this was something I didn't know how to do in CS5 before I watched Dave's tutorial.

From Wiki: The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of explosion, the supernova would have appeared brighter than Venus in the sky, and visible in daytime. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). While previous distance estimates have ranged from 1200 to 5800 light-years, a recent determination of 2400 light-years is based on direct astrometric measurements. The Hubble Space Telescope captured several images of the nebula. The analysis of the emissions from the nebula indicates the presence of oxygen, sulfur, and hydrogen. The Cygnus Loop is also a strong emitter of radio waves and x-rays.

De SkySafari Plus: La nebulosa Eta Carinae fue descubierta en 1752 desde el Cabo de Buena Esperanza en Sudáfrica. Es un objeto característico del hemisferio sur, visible a simple vista
Es una de las nebulosas difusas más grandes en el cielo y una de las regiones de mayor emisión de HII en la vía láctea. Está a una distancia de entre 6.000 y 10.000 años luz de la tierra.
Alrededor de la estrella central, Eta Carinae, existe una pequeña nebulosa que se cree fue originada en un estallido enorme en 1841, haciéndola brevemente la segunda estrella más brillante en el cielo.
