stacked with deepskystacker
initial processing with pixinsight 1.5
- normalization of ngc1977 vs. m42 data
- all subs aligned to luminance data
- rgb merge
- combined ngc1977 and m42 data with pixel math to produce a single image
- deconvolution
- histogram stretch (x10) of merged rgb data and luminance data
enfuse:
- HDR blend of all exposures generated in pixinsight
- luminance: hard mask, mean=0.54026, sigma=0.23154
- rgb: hard mask, mean=0.64026, sigma=0.23154, l-star grey projector
- had to duplicate the unstretched exposure 8 times to recover trapezium
photoshop: remove geosynchronous satellite streaks
pixinsight:
- histogram fixes and color calibration of rgb images
- histogram fixes, dark structure enhancement and atrous wavelets on luminance image
- LRGB merge
- chop composite image back into 2 separate images
- further histogram fix of ngc1977 to better match m42
hugin:
- stitch of ngc1977 and m42 images
lightroom:
- fix red/magenta saturation (pixinsight is running without color management... long story)
- crop
comments: the deconvolution is kind of bad... its heavy duty signal processing work that requires more patience than i could muster. as a result i've got some ringing and sharpening of bogus features.
it was really hard to get the two images to have the same brightness even though the exposures were the same. different nights, different amount of moon, different sky transparency all conspire to make two identically exposed images very different.
finally this is HDR so although the relative brightness between m42 and ngc1977 should be correct, the dynamic range of both have been greatly compressed. most other treatements of these objects show ngc1977 much fainter than seen here. but what is realistic when dealing with astrophotography?

More playing with the SBIG and 300mm Nikkor lens. Hung out in the back garden and collected a couple hours on this target. There was a stiff breeze, so the guiding is a little off, still I really do like the dusty contrasts. Would love to get to a dark site to collect some color data!

It's all about the NGC 7538 region in the constellation Cepheus.
This region of active star formation is located about 9,100 light-years from Earth.
The picture is a result of more than 78 hours of integration time in narrow band and rgb channels.
I could say that is a more complicated target than I thought at the beginning, it was difficult to post process this image due the high dynamic range needed to reveal all the details.

Messier 16 – M16
Constelación en que se encuentra: Serpens
Distancia: 7.000 años luz
De SkySafari:
Messier 16 (#M16) es una nebulosa ubicada en la constelación Serpens. Corresponde a una región de formación de nuevas estrellas. En la imagen también se ve el cúmulo NGC 661, descubierto en 1745. M16 fue incluida por Charles Messier en su catálogo en 1764.
En 1995 el telescopio espacial Hubble tomó la imagen más famosa de esta nebulosa, conocida como los Pilares de la creación. Los pilares se ven en el centro de la imagen.
Estudios de 2007 realizados con el telescopio espacial Spitzer han sugerido evidencia de que los pilares fueron destruidos hace unos 6.000 años por la explosión de una supernova. Si se tiene en cuenta que estaban a 7.000 años luz, su nueva forma posterior a la destrucción, solo será visible desde la tierra dentro de un milenio.

NGC7635
Constelación en que se encuentra: Cassiopeia
Distancia: 1.400 años luz
De SkySafari:
#NGC7635, conocida como Nebulosa Burbuja fue descubierta en 1787 por Wilhelm Herschel. Es el resultado del viento estelar causado por la estrella SAO20575, de magnitud 8.7 que en la imagen aparece a la derecha dentro de la burbuja. La estrella es caliente, con temperatura de unos 36.000 grados C; el diámetro es 24 veces el del sol y su masa equivale a 49 masas solares.
La forma de la nebulosa es causada por el choque del viento estelar contra la nube de gas alrededor de la estrella, que también causa que brille. Se espera que SAO20575 termine como una supernova dentro de los próximos 20 millones de años.

The Trifid Nebula, also known as Messier 20 (M20) or NGC 6514 resides near the center of our Milky Way galaxy in the constellation Sagittarius. It is a relatively young (less than one million years old) star forming region approximately 5200 light years from earth.
It consists of a reddish emission nebula caused by ionized hydrogen, a reflection nebula … the blue light reflected from nearby stars, and a dark nebula from obscuring dust clouds.
It actually gets its name (Trifid) from those dark nebula gaps which appear to divide it into three parts or lobes.
This is 94 minutes of 10 second images taken with the SeeStar telescope, processed in PixInsight, Nik Collection software, and Topaz sharpening.

Another object from this nice catalogue of faint nebula.
Long integration of 53 hours using two narrow band filters mainly, searching the limits of the equipment and my own process skills.
It's not a popular target probably because is difficult and usually is not showing so much detail due to the high dynamic range, the core is bright, really bright compare with the faint surroundings.
Sh2-235 is the most central and brightest nebula of an H II region known as G174+2.5; it is observed in the direction of the northern part of the Aur OB1 association and includes the nebulae catalogued as Sh2-231, Sh2-232, Sh2-233 and Sh2-235, identified as individual nebulae in the 1959 census of H II regions. Although in the optical images they appear as distinct nebulae, in reality they all belong to a single giant molecular cloud, of which some parts appear illuminated by young and hot stars. This cloud is located in Perseus' Arm at a galactic latitude that places it slightly off-center with respect to the center of the galactic disk; the distance measurements indicate a range between 1600 and 2000 parsec, so it is normally indicated as about 1800 parsec (5870 light years).

In March 2025, I embarked on an astrophotography project focusing on Messier 81 and its neighboring galaxies. I captured the luminance data at the Hohen List observatory in the Eifel region, while the RGB channels were taken earlier from my home in Koblenz. Combining these, I achieved a total exposure time of 6 hours and 20 minutes. The resulting widefield image prominently features Messier 81 at the center, with Messier 82 to its left, the Garland Galaxy below, and NGC 2976 in the upper right. This project served as a testament to the capabilities of my telescope-camera setup, delivering impressive results even with a relatively short integration time.
Around 600 shots with 70-200mm exposure of 0,8 seconds.
Processed stacked in Pixinsight.
No equatorial or azimutal mount.
Using the MARS data in the latest PixInsight I got the best result I've gotten from M45.

The Lion Nebula.
Found in the constellation of Cepheus, the Lion Nebula when viewed from just the right perspective, actually does represent a lion. At approx 10,000 light years away
it is made up of an emission nebula and a reflection nebula.
Not bright enough for visual observation sadly, it does however make for a great imaging target.

Nebulosa California (California nebula) #NGC1499
Constelación en que se encuentra: Perseus
Distancia: 1800 de años luz
De SkySafari:
NGC 1499 es una nebulosa de emisión en la constelación Perseo que recibe su nombre por el parecido con el mapa del estado de California de Estados Unidos. Fue descubierta en 1885.
Su brillo superficial es bajo. Está a unos 1800 años luz del sistema solar, en el brazo de Orión de la Vía Láctea. Es una región en la que, por su alto contenido de hidrógeno, se han formado muchas estrellas masivas y luminosas. La estrella luminosa es Menkib (Xi-Per), de color blanco azuloso, e ilumina la nebulosa.

The Elephant's Trunk nebula is a concentration of interstellar gas and dust in the star cluster IC 1396 – an ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown above is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star that is just to the west of IC 1396A. The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.(Explore Scientific ED127, ZWO ASI2600MM, ASIAIR, EAF, EFW, AM5, Antlia SHO 3nm, Pixinsight, Photoshop).

A Cluster of Pearls in the Southern Skies ( NGC 3766 " The Pearl Cluster" ) by Mike O'Day ( 500px.com/MikeODay )
Shimmering like a pearl to the naked eye, this open cluster of mostly young blue stars ( known as the "Pearl Cluster" ) is approximately 5500 light years from Earth and was discovered by Abbe Lacaille in 1752 from South Africa.
This HDR "true colour" image is constructed from 11 sets of exposures ranging from 1/4 sec ( to capture the centre of the brighter stars ) through to 240 seconds ( for the fainter stars of the Milky Way ). Total exposure time was around 5 hours.

A large stellar nursery in the constellation of Scorpius some 6,000 light years away from us.
The nebula is very faint, making it difficult to observe, despite it's size of around 250 light years.
The image consists of 19 data sets of 5 minute LRGB each.
Data was captured online using the Chile 2 telescope at Slooh.com

The Trifid (M20) is a combination emission (red) and reflection (blue) nebula that is located in the constellation Sagittarius. It gets its name because the main section of the nebula is divided by dust lanes into roughly three parts.
Taken over two nights from a relatively dark site on the slopes of Palomar mountain, this image consists of 1022 sub-exposures that were each exposed for 5 seconds using an uncooled QHY5-III 178C camera and a Stellarvue SV80ST2 telescope (the latter operating at f/4.8 using a 0.8X reducer/corrector, total exposure integration time about 85 minutes). Using such short exposures greatly simplifies the image capture process since there was no need to guide the Celestron AVX mount that carried the scope and camera.
Image capture was done with SharpCap, image processing was done in PixInsight and Photoshop CC2015.
