The white rhinoceros, white rhino or square-lipped rhinoceros (Ceratotherium simum) is the largest extant species of rhinoceros. It has a wide mouth used for grazing and is the most social of all rhino species. The white rhinoceros consists of two subspecies: the southern white rhinoceros, with an estimated 16803 wild-living animals, and the much rarer northern white rhinoceros.
The northern subspecies had very few remaining individuals, with only two confirmed rhinos left in 2018 (two females: Fatu, 18 and Najin, 29), both in captivity. Sudan, the world's last known male Northern white rhinoceros, died in Kenya on 19 March 2018 at age 45.
Northern white rhinos, like their close cousin the southern white rhino, feed exclusively on short grass, which their massive mouths hoover up with the efficiency of a living, breathing lawnmower. They occupy a much more open savannah habitat than black rhinos, which feed on shrubs and other foliage.
The northern white rhinoceros or northern square-lipped rhinoceros (Ceratotherium simum cottoni) is considered critically endangered and possibly extinct in the wild. – Wikipedia

The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares with Messier 101. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, which includes the Milky Way, the Andromeda Galaxy and about 44 other smaller galaxies. It is one of the most distant permanent objects that can be viewed with the naked eye.
The galaxy is the smallest spiral galaxy in the Local Group and it is believed to be a satellite of the Andromeda Galaxy due to their interactions, velocities[7] and proximity to one another in the night sky. It also has an H-II nucleus.[8]

Here is my first image in LRGB since my return after some time out.
Some nice data to play with from SSRO - spent a lot of time working on the layers of colour and tone to try and provide as many perceived details as possible.
Plate solving does not seem to recognise this area - maybe it is too busy!
There are a plethora of images from the main blue reflection nebulae a variable nebula, some dark nebula and for good measure some Herbig-Haro objects.
Hope you enjoy.

This was a challenge to process having to be very delicate and patient with any detail, lots (and i mean lots) of small iterations provided the detail whilst, hopefully, not being too aggressive and keeping the overall image with a nice clean feel.

With this image I bring you a detail in the Carina nebula, a poorly described object, a cosmic bubble, possibly produced by the stellar wind of a star. It is located north of the mystical mountain that can be seen in the image, in addition to other structures. The image is a large but detailed crop of the image taken 04/07/2021 in Namibia with the 20 "remote telescope with a FLI 16803 monochrome camera and H alpha and OIII filters. The shots were approximately two hours per filter.
The processing has been done in a HOO palette and I wanted to highlight this structure in false color. The processing has been done with pixinsight and PS.

M1 - An Explosion in Space
Sky-watchers on Earth witnessed and wrote about a bright “supernova” (literally meaning “new star”) in the year 1054. What they were really viewing was the birth of rapidly expanding clouds from an exploding star. By the year 2021, roughly one thousand years later, these clouds have covered a distance of nearly 10 light years, and they continue to expand at a rate of about 1000 kilometers per second.
In 1840, after viewing this supernova remnant through a telescope and sketching it, astronomer William Parsons thought that it looked like a crab, and the name “Crab Nebula” caught on. If you can't see such a crab, you're not alone! With modern cameras we can collect so much more light and detail than that which could be previously captured with the eye and eyepiece combo, so to me (and probably to you) it looks more like, well, an explosion in space.

Hi all - it's been a while. Apologies for absence and lack of support etc - life been getting in the way.
Having not opened PI for 6+ Months (so be kind :) )I thought I would start with something relatively straightforward to dust the processing down a little, sure there are a few errors. Bits in Spain are taking shape so will have an abundance of data this year, best I get ready for that!

Here we have Thors Helmet - NGC 2359.
This is one of those targets that you see and just want to get a picture of, one day!
So finally got around to having a go.
This target lent itself well to a depth of field experiment, the foreground area being very sharp and contrasting against the softer background. Would be interested in hearing if this approach has worked?
Wikipedia says....
GC 2359 (also known as Thor's Helmet) is an emission nebula in the constellation Canis Major. The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution. It is similar in nature to the Bubble Nebula, but interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape and curved bow-shock structure of Thor's Helmet.
It is also catalogued as Sharpless 2-298 and Gum 4.
The nebula has an overall bubble shape, but with complex filamentary structures. The nebula contains several hundred solar masses of ionised material, plus several thousand more of unionised gas. It is largely interstellar material swept up by winds from the central star, although some material does appear to be enriched with the products of fusion and is likely to come directly from the star. The expansion rate of different portions of the nebula varies from 10km/s to at least 30km/s, leading to age estimates of 78,500 - 236,000 years. The nebula has been studied at radio and x-ray wavelengths, but it is still unclear whether it was produced at the class O main sequence stage of development, as a red supergiant, luminous blue variable, or mainly as a Wolf-Rayet star.
NGC 2361 is a bright knot of nebulosity on one edge of the central ring of NGC 2359.
This photo was taken as part of the competition from ChileScope.com (www.chilescope.com/), thanks to the access granted to raw materials from a remote telescope in the mountains in Chile.

_________________________
Explanation: Why does this starfield photograph resemble an impressionistic painting? The effect is created not by digital trickery but by large amounts of interstellar dust. Dust, minute globs rich in carbon and similar in size to cigarette smoke, frequently starts in the outer atmospheres of large, cool, evolved stars. The dust is dispersed as the star dies and grows as things stick to it in the interstellar medium. Dense dust clouds are opaque to visible light and can completely hide background stars. For less dense clouds, the capacity of dust to preferentially reflect blue starlight becomes important, effectively blooming the stars blue light out and marking the surrounding dust. Nebular gas emissions, typically brightest in red light, can combine to form areas seemingly created on an artist's canvas. Photographed above is the central part of the nebula IC 4603 surrounding the bright star SAO 184376 (actually 8th magnitude) which mostly illuminates the blue reflection nebula. IC 4603 can be seen near the very bright star Antares (1st magnitude) toward the constellation of Ophiuchus.

M51
Contains: NGC 5195, Whirlpool galaxy, M 51, NGC 5194
Here is my look at M51.
The Whirlpool Galaxy, also known as Messier 51a, M51a, or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus in the constellation Canes Venatici. In the Catalogue of Named Galaxies, it is called Typhon Canum Venaticorum, after the Greek god Typhon. It was the first galaxy to be classified as a spiral galaxy. Recently it was estimated to be 23 ± 4 million light-years from the Milky Way, but different methods yield distances between 15 and 35 million light-years. Messier 51 is one of the best-known galaxies in the sky. The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars. The Whirlpool Galaxy is also a popular target for professional astronomers, who study it to further understand galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions.
I was interested to see how much detail could be found in the data. [Wikipedia]
I recently saw an article on AFP-R to maximise detail, however, it is very similar to what I already do running small iterations of LHE at different settings in PI and stacked high pass layers selectively applied in PS.
