Messier 51, the Whirlpool galaxy in the northern constellation of Canes Venatici
This is an integrated image of over 23 hours of data captured on a QHY183C camera with a William Optics Zenithstar 103 telescope. All post-processing was carried out in PixInsight.
This is a faint emission nebula in the Large Magellanic Cloud. It has been debated whether this formation is from a supernova or solar winds. More recent observations of the spectrum indicate it is not a supernova remnant.

The Milky Way rises near Mount Tamalpais in Marin County, California. Mount Tamalpais is often considered symbolic of Marin County. Much of Mount Tamalpais is protected within public lands such as Mount Tamalpais State Park, the Marin Municipal Water District watershed, and National Park Service land, such as Muir Woods. Pride of Madeira is an evergreen sub-shrub native to the island of Madeira Portugal, near Morocco. The beautiful yet tough plants are able to tolerate drought, rocky soil, & coastal conditions. The flowers are very ornamental, blooming on huge 2' long spikes. The flowers are blue with red stamens, which gives it a fuzzy blue-violet look. Pride of Madeira’s flowers produce large amounts of nectar for bees including honey bees, & butterflies.

In this Hubble Palette version (SHO) the H-Alpha is mapped to green channel, SII is mapped to red channel and OIII is mapped to the blue channel. The raw data was preprocessed using Pixinsight, the stars were removed using a tool called Starxterminator and the stars were later replaced during Post Processing in Photoshop CC with the more naturally colored stars from the RGB data.

This starless image of The Soul Nebula is work in progress, captured recently from Grand Mesa Observatory’s System 1 using the new QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on the Takahashi 130 FSQ that we have the honor of testing for QHYCCD.
I’m not a big fan of starless images as a finished subject however I wanted to show you this as I often make my images starless as part of my post processing routine so as to reduce the star size and create more emphasis on the deep sky object. Up until recently I was using the stand alone version of starnet but now that Pixinsight have integrated it into their own software I find it much less time consuming and easier to use. I was so impressed with the starless image result on the soul nebula that I decided to share it. This orientation reminds me of a map of Australia where I grew up.

I recently published a well-received version of M81, it seemed rude not to process its compatriot.
In order to realise all the details you could argue the image is actually a L, L, L, L, L, L, L, L, L, L, Ha, Ha, Ha, Ha, Ha, RGB, RGB, RGB, RGB, RGB, RGB, rather than just a HaLRGB image!
In order to realise all the details I have been persisting with my (very time-consuming approach) of building the main layers from multiple stretches of the main frames from very dark to very light, a manual HDR (but with full control) most of the work is done in PI but the layering and masking has to be done in PS for control. I am finding at the longer focal lengths this really lets me realise all details from the dark (often washed out by brightness on such targets) to the very light, I can even stretch beyond the limit to realise the fainter details.
Anyway, hope you all like - not a quick process taking about 8 hours solid to process over a few days.
As well as realising some great detail I was pleased to see the inner structures showing well including the mushroom shape to the right and the double boundary of the left side (inner ring just about visible)

The Rosette Nebula is a cloud of dust containing enough gas and dust to make about 10,000 stars like our Sun. In the centre of the nebula is a cluster of hot, bright young stars. These are warming up the surrounding gas and dust, making it appear bluer. The small, bright white regions are cocoons of dust in which huge stars are currently being born. These “protostars”, each one of which will probably become a star up to ten times more massive than the Sun, are heating up the surrounding gas and dust and making it clow brighter. The smaller, redder dots on the left side and near the centre of the image also contain protostars, but these are smaller, and will go on to form stars much like our Sun. Just as the centre of the nebula contains bright young stars, in a few tens or hundreds of millions of years these stars will have died, but the protostars will have evolved into fully-fledged stars in their own right. In this way, the star formation will move outwards through the nebula. Hubble Palette of SHO data from Telescope Live.

This is night two (and that's it for well over a week) this came about by recollimating the mirrors on the mount. In short you have to line up the mirrors by following steps and "eyes" to see just where things are each adjustment is not on one screw but three bottom or main mirror and the secondary or top mirror. It better than the first shot but still could be better.
I have to remove the clips that hold the mirror and put silicone under the mirror to hold it in place gives cleaner stars. This also was stacked with the right flats the first had none as it was more a night to get focus which the Esatto did easily. In the end I let Nina look after the mount to get an idea how the stars as I never got a chance to recollimate the telescope after I put it on the mount.
So how do you like your Dragon Egg flipped

The Tarantula Nebula, also known as 30 Doradus and Caldwell 103, is a massive emission nebula with one of the most active star forming regions known within our Local Group of galaxies. This image only captures part of the entire object, with the Tarantula Nebula spanning some 600 light years in diameter and containing more than 800,000 stars and protostars. It lays outside of our Milky Way galaxy in the satellite galaxy called the Large Magellanic Cloud. At a 180 thousand light years away, its size is so massive that if it were as close as is the Great Orion Nebula is from earth, that it would brightly light up half our nights sky.
Thanks for looking, take care.

Imaged using the Celestron C14 Edge HD telescope in dome 3 at Los Coloraos observatory in Gorafe, Spain.
A really popular image for astro photographers . It is bright full of interesting features making it a target for all focal lengths.
I have imaged this galaxy many times with smaller telescopes, but had the opportunity to image at 3900mm using the C14. 14 hours of data over three nights in May 2024. Really happy with the results.
A high resolution image with imaging details can be found on my Astrobin page at: astrob.in/2qskmt/0/

Captured on September 27th at Grand Mesa Observatory using QHYCCD’s latest offering the QHY410C Back Illuminated Full Frame one shot color CMOS camera that we have the honor of testing.
This is work in progress as the conditions on the night of capture were quite poor with smoke from California wild fires that have plagued us for the past 3 months.
A stream of red emission dominates this close up shot of part of Barnards Loop otherwise known as Sh2-276 , a large emission Nebula and part of the Orion Molecular Cloud Complex. The image also nicely captures areas of dark nebulosity LDN 1622 which lies at a distance of 500 light years as well as the blue reflection nebula of M78 located some 1,600 light years away, M78 hosts 17 Herbig-Haro objects (patches of nebulosity created by young stars whose jets collide with nearby dust and gas).

This is some thing I have always wanted to take after I took it on Feb 2019 this is purely us under southern skies. So I used my 105mm Nikon lens to take a 3 shot panorama of the area over the last three night. The Points of Interest is what we see every night the Southern Cross and the Pointers not forgetting the head of the Emu between them both. The detail in the shot was an outstanding bonus but certainly no spectacular nebula in the shot its all about the stars and there is plenty of them. This was 80 shots a night for the three night getting each panel together. Each night it was a manual focus ZWOASI071MC -10 80 shots per the 3 nights

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.

Wikipedia:
Esta galaxia seguramente fue descubierta por el astrónomo italiano Giovanni Battista Hodierna antes de 1654, quien la agrupó junto con el cúmulo abierto que hoy conocemos como NGC 752. Charles Messier la descubrió independientemente en 1764, catalogándola como M33 el día 25 de agosto. La galaxia del Triángulo también fue catalogada por William Herschel el 11 de septiembre de 1784, asignándole el número H V.17. M33 se encuentra entre las primeras "Nebulosas espirales" identificadas por el astrónomo irlandés William Parsons el tercer "conde de Rosse".
Herschel designó la mayor región H II de esta galaxia (nebulosa de emisión difusa que contiene hidrógeno ionizado) como H III.150 separándola de ella y nombrándola NGC 604. Vista desde la Tierra, NGC 604 está localizada al noreste del centro galáctico, y es una de las regiones H II más grandes conocidas, con un diámetro de 1500 años luz y un espectro similar al de M42.
Aunque no puedan compararse con NGC 604, otras regiones HII de Triángulo son también tan grandes y brillantes que tienen su propio número NGC, cómo por ejemplo NGC 588, NGC 592, y NGC 595.5
Se dice que la Galaxia del Triángulo, es la única galaxia después de M31, que puede observarse a ojo desnudo bajo condiciones excepcionales, aunque también hay antiguas anotaciones que mencionan que la galaxia espiral M81, situada hacia las estrellas de la constelación septentrional de la Osa Mayor, también se puede observar a simple vista; pero para muchas personas M33 sigue siendo el objeto visible a simple vista más distante. Sin embargo, es muy grande y difusa y el mejor instrumento para observarla son unos binoculares, pudiendo incluso bajo condiciones muy buenas apreciarse con ellos sus brazos espirales, o un telescopio trabajando a muy bajos aumentos. Lo más importante e interesante que han destacado los expertos de M33 es que se trata de un auténtico hervidero de estrellas nacientes, en donde surgen soles a un ritmo muy superior al que nos tiene acostumbrados nuestra Vía Láctea, conteniendo además de NGC 604 algunas de las asociaciones estelares más ricas y brillantes del Grupo Local.6
M33 tiene un décimo de la masa de la Vía Láctea y mide unos 60000 años luz de largo, aproximadamente la mitad que nuestra galaxia.
Un reciente estudio llevado a cabo por el telescopio de infrarrojos Spitzer muestra que M33 es mayor de lo que puede apreciarse en el visible, llegando sus nubes de polvo más allá de lo que se aprecia en las fotografías. Se piensa que ello es debido a las explosiones de supernova y/o a los vientos solares de estrellas jóvenes7
M33 está unida por una corriente de hidrógeno neutro y según estudios recientes también por diversas corrientes de estrellas a M31, además de tener la parte más externa de su disco de estrellas y gas distorsionadas, lo que indica un acercamiento pasado entre las dos, y su destino final puede ser o acabar chocando y fusionándose con la segunda (algo que se desconoce cuándo ocurrirá, pero quizás antes de la colisión entre M31 y nuestra galaxia y que refuerzan investigaciones recientes, que muestran que hubo un acercamiento entre ambas galaxias hace 2500 millones de años y que se producirá otro considerablemente más violento dentro de 2000 millones de años o acabar participando en la colisión entre la Vía Láctea y Andrómeda, bien colisionando con nuestra galaxia, bien orbitando la galaxia resultante de la colisión de las dos antes de acabar fusionándose también con esta, o incluso siendo expulsada del Grupo Local.
Como nota curiosa, desde esta galaxia se ve a Andrómeda (M31) prácticamente de frente, ofreciendo esta gracias a su relativa cercanía un aspecto impresionante; sin embargo, se vería muy cercana al plano galáctico, por lo cual el polvo la oscurecería y enrojecería, llegando incluso a hacerla invisible en el peor de los casos.
Nuestra galaxia se vería parecida a como se ve desde Andrómeda, aunque con un ángulo más abierto, un poco menor y menos brillante, y a buena altura sobre el plano galáctico.

New processing, old data. Trying to learn as much as I can about different processes in PixInsight. I feel as though my processing skills are lacking and do not reflect my taste, and so I've made a goal for myself to revamp my style and skill level of processing. This go around was learning the masked stretch process with Harrys Astroshed tutorial (best around might I add). A far better approach to star treatment then I've done before, always love to learn better ways in processing and it never stops! That's the fun in this hobby.

2020 was an unusual year as we all know. It was a very busy year for me working on a 3D Animated Motion Capture Series and Music Video from home, and as a result I didn't manage to image much.
About the Nebula:
The Elephant's Trunk Nebula is a concentration of interstellar gas and dust with-in the much larger ionized gas region IC 1396 (located in the constellation Cepheus), about 2,400 light-years away from Earth.
Reprocessing old data:
I don't often do this, but decided to reprocess old data from 2017 in the SHO Palette (SII, Hα & OIII). IC 1396 was imaged on my first "budget friendly" Telescope (a 6" GSO Newtonian Astrograph). This was one of my first attempts at Narrowband Astrophotography, and the data that I captured back then was less than ideal, but a nice challenge to process. It is all part of the never ending lifelong learning experience.
I would like to revisit the IC 1396 region again, and image the very interesting surrounding structure with my wide-field APO Refractor Telescope. It is interesting to look back and see what you've learnt (which is why I've always kept my old learning images as a record).

This is the view I was after when the USB plug broke on the camera March last year. This proved to be a marathon getting images as the mount threw up a curveball and at this stage still not sure if I have found the answer to the problem.
This will be my last photo for a very long time as I do a huge panorama of the Milky way of some 40 odd shots. Enjoy it.
