I couldn't leave well enough alone.
With the success of the pass through Noiseware of the previous example, I tried to go for broke and see what I could make of a deep stretch.
So in this case, I went back to the stacked FIT file from DSS that was solved and cropped. Reworked the DBE, SCNR to remove the green, and then ran the masked stretch script to boost the midrange. Then stretched the results to give the view seen here. Passed this as 16bit TIFF to Noiseware and then processed it there. Back to PI for a run through some masked curves for saturation and lightness and an unsharp mask to pop the small stars.
I think I'm really done with this image.

The "Cave Nebula", in the centre of this image, is a popular name for Sh2-155, an emission nebula in the constellation Cepheus. It appears cave-like due to a dark, hollowed-out area surrounded by a bright, ionized gas rim, which is an active star-forming region (H II region). Located approximately 2,400 to 3,000 light-years away, it is part of a larger star-forming complex called Cepheus B.
The blue area of nebulosity to the upper left of the cave is the reflection nebula vdb155.
Andromeda Galaxy (M31), 09/27/2020
Took advantage of the unexpectedly clear skies and went to Belfair Start Park for a few nights. Last month I took a picture of M31 with my small system (T5i, 200mm lens and a star tracker) and I thought I’d compare it to my full-size setup. Yep, you guessed it, it’s a much better photo.

The Wizar Nebula, NGC 7380 is a young open cluster of stars in the northern circumpolar constellation of Cepheus, discovered by Caroline Herschel in 1787. The surrounding emission nebulosity is known colloquially as the Wizard Nebula, which spans an angle of 25′. German-born astronomer William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun, in the Perseus Arm of the Milky Way.

Very difficult object to image. I wasn't planning on imaging it but rather the Globular Cluster itself. When I returned home from Africa, Rich Jakiel was looking at the image and suggested we get a detailed finder chart of the PN just in case it was there. We secured a finder chart, very detailed, from Hubble images. The article mentions the red star and the blue star above and below the PN. The PN itself is the light blue spot between the two stars.
Cygnus Loop, or Veil Nebula, 60 two-minute exposures taken on August 16, 2020. A three-degree-wide (6 full moons wide) spherical expanding bubble of glowing gas from a star that exploded as a supernova about 21 thousand years ago. About 130 light-years in diameter, at a distance of about 2000 light-years.

The Western Veil Nebula (or the Witch's Broom Nebula for obvious reasons) on the top right along with Pickering's Triangle.
The image FOV is about 2 degrees wide, making it four times as wide as the full Moon. It would be great if our eyes were sensitive enough to see these terrifyingly large things in the sky.
The reds are mainly hydrogen alpha emission (areas of ionized hydrogen) and the bluish-green is due to Oiii emission corresponding to regions of doubly ionized oxygen.
The Veil Nebulae are part of the larger Cygnus Loop supernova remnant which is an expanding spherical shell material left over from an exploding star.
This was also the session where I finally got plate solving to work so now the rig knows what it is looking at, then compare it to what it should be looking at and then make the necessary adjustments.

The Emerald Bloom of Sh2-36: A Hundred Hours of Starlight Unfolding
In a quiet region of the constellation Serpens, the emission nebula Sh2-36 Nebula reveals itself not as chaos, but as a cosmic bloom. Captured over 100 hours of integration from Desert Bloom Observatory in Arizona, this deep image transforms faint hydrogen gas into a luminous structure resembling a flower unfolding in green radiance.
This celestial “bloom” is an H II region, where intense ultraviolet radiation from newly formed stars ionizes surrounding hydrogen gas. As electrons recombine with protons, they emit light—most prominently in the hydrogen-alpha wavelength—tracing the hidden architecture of stellar birth. The unusual green tones arise from a creative mapping of narrowband data, translating invisible wavelengths into a visual palette that bridges science and imagination.
Filaments stretch like petals, shaped by stellar winds and radiation pressure, while darker lanes of interstellar dust weave through the nebula, sculpting contrast and depth. These structures are not static; they evolve over millions of years, collapsing under gravity to form new stars, while energetic radiation simultaneously disperses the very clouds that created them.
What appears here as a delicate flower is, in reality, a dynamic and powerful environment—where matter cycles between creation and destruction. Each photon captured in this image traveled across space to reach the detector, contributing to a signal refined through patience, precision, and time.
From the desert skies of Arizona, this portrait of Sh2-36 is both a scientific record and an artistic interpretation—a reminder that the universe, even in its most complex processes, can resemble something beautifully familiar: a bloom in the dark.

Torn by Gravity: The Distorted Heart of Markarian’s Chain
In the crowded realm of the Virgo Cluster, nearly 55 million light-years from Earth, lies a galaxy that refuses symmetry. NGC 4438, once likely a graceful spiral, now appears stretched, warped, and disturbed — its arms twisted into irregular arcs as though caught mid-struggle.
This distortion is not random. It is the consequence of gravitational interaction — a close encounter with neighboring galaxy NGC 4435 and the immense gravitational field of the Virgo Cluster itself. Over millions of years, tidal forces have pulled at its stars, gas, and dust, reshaping its structure and igniting subtle waves of star formation within the chaos.
Captured here from Desert Bloom Observatory in Arizona under dark desert skies, this image isolates the dramatic anatomy of NGC 4438 within Markarian’s Chain — a curving procession of galaxies bound together by gravity. Markarian’s Chain is part of the greater Virgo Cluster, the nearest large galaxy cluster to the Milky Way, containing thousands of galaxies engaged in slow cosmic dance.
What we witness is not destruction, but evolution. Galactic encounters like this are fundamental to cosmic growth. Through collision and tidal strain, galaxies exchange material, trigger starbirth, and gradually transform their morphology. The scars we see are signatures of interaction — gravitational fingerprints written across tens of thousands of light-years.
NGC 4438 reminds us that even on scales beyond imagination, the universe is dynamic. Galaxies are not static islands of stars; they are living systems shaped by encounter, pressure, and time.
In this torn spiral, gravity becomes visible.

Heart and Soul Nebulas under a nearly full moon. 73x3 minutes with a modded Nikon D600 through a WO Redcat 51 and Optolong L-Enhance filter
Do you see the alien skull? This is the Rosette Nebula, a region of atomic hydrogen that has been ionized (HII region) by the star cluster in the middle.
The plan was to take about 40 x 200s exposures resulting in over 2 hours of integration. However, a tree came out of nowhere and ruined all the best laid plans of mice and screwed up guiding in most of the photos. At the end only 7 images were usable resulting in just under 25 mins of data.
The structure is about 5000 ly away and 130 ly wide.

M57: A sunlike star ran out of hydrogen fuel about 1600 years ago and became a red giant, shedding it's outer layers to form a sphere of expanding gas as it subsequently contracted into the white dwarf in the center of the ring. The object's name is 'Messier 57', or the 'Ring Nebula'. The white dwarf has the mass of our Sun, but only the diameter of the Earth. The light this dead cinder of a star emits as it cools makes the expanding gas sphere glow. The edges of the sphere appear brighter than the center since we're seeing only a thin layer at the center, but a great depth of glowing gas at the edges, piled on top of each other. This is the fate of our sun, in about 5 billion years. This object is quite small in our sky, being 1/24 the diameter of the full moon. It is perhaps 2570 light years away. This photo is built from 63 one-minute exposures, taken on Aug 6 2020.

I cheated!
So I went back to my data again in PI. Tried reading through the PI tutorials on using ACDNR and I was able to understand a lot more about how to use the tool. Got something so so out of it. I really wasn't too happy about the results. When I put some before and after images together, I was turned off by the views.
So on a whim, I exported a 16 bit tiff from before the ACDNR exercise and ran that through Noiseware. Given what I've learned in PI, I was able to tweak that software a lot faster. The results that I got in less than 10 minutes of working were cleaner and much less grungy than what I'd been getting after several hours in PI. I know that I'd be able to duplicate the same results, I just don't know the settings.
Anyhow, I was able to reattach the FIT headers and Annotate the image.
So, it's done now.
