Companion notes

This sweeping mosaic follows one of the richest stretches of the summer Milky Way, beginning with the Nest, NGC 6604, and continuing past the Eagle Nebula, M16, NGC 6605, IC 4701, and the Swan Nebula, M17. From there, the view descends through the dense star fields of M24, the Small Sagittarius Star Cloud, to the open cluster M21, the Trifid Nebula, M20, and finally the vast Lagoon Nebula, M8.

The Eagle is home to the iconic Pillars of Creation, while the Swan’s bright arcs trace an immense region of active star formation. M24 is not a single cluster, but a window through foreground dust that reveals a remarkably dense field of Milky Way stars. Farther south, the Trifid combines emission, reflection, and dark nebulosity, while the Lagoon anchors the panorama with its broad clouds of glowing hydrogen and newly formed stars.

This image was captured with Seestar S30 Pro and S50, using a combination of the ZWO built-in LP filter and Otolong L-eXtreme dual-narrowband filters.

I am in the process of collecting SII data using SVBONY SV220 in order to complete a SHO palette rendering.

processing notes:

All images captured with Seestar S30 pro and S50, over a period of a few weeks. HA data was captured using L-eXtreme, L-Quad, or internal LP filters.
This is about 25 seperate panels, all individually stacked in Siril (Naztronomy script, 1.4x drizzle, sigma rejection, noise rating) and cleaned (cropped, BG extraction, SPCC, aberation removal), then those panels were stacked with light feathering and star weighting, then post proccessed.
processing this image in siril absolutely murders my machine (m2 macbook air, 16GB ram) star removal takes about 30 mins. Scunet took about an hour.
I only did relatively light post work with this, because i wasn’t really intending on sharing, and there’s more data that i plan on collecting.
post processing was: scunet denoising, statistical stretch, color grading. this was too much data for veralux to handle, so I brought it into pixelmator.
cropped pixel dimensions are 20833x4317, about 90 megapixels.
uncropped image is about 3GB, cropped is about 2GB.

North America Nebula, captured with traditional astrophotography

This is the North America Nebula, along with the Pelican Nebula. This is far from the most amazing rendition of this subject; actually, this isn’t even my best rendition of this subject. But tonight, it’s the image that I’m most proud of, because it’s the first image that I successfully captured and processed using traditional astrophotography gear instead of “smart telescopes.”

Smart telescopes are absolutely wonderful. I began my astronomical journey through our universe with a Seestar S50 six months ago, and I absolutely adore using it. For the past few months, though, I have been slowly accumulating the pieces needed to accomplish what I’m sharing tonight. I started with a secondhand tripod and equatorial mount, then added my 20-year-old Nikon D5300. I purchased an Askar FMA135 when it was incredibly discounted, and assembled a hodgepodge of connectors and adapters to string it all together, including a 1.25"-2" step-up adapter so that I could use my Optolong L-Quad Enhance filter.

setupMy Seestar S50 and the new FMA135/D5300 rig, framed around the rich Cygnus region of the Milky Way

I spent many late hours in my yard, (re-)learning about polar alignment, manual star alignment, ISO, intervalometers, and manual focusing techniques. Then, once I finally got a few hundred subs, I was introduced to the joys of calibration, stacking, and working with much larger, more detailed data.

All of this has given me an incredible new appreciation for both traditional and smart astrophotography. I am even more blown away by the incredible results that I’ve seen people share from their self-assembled, cooled, auto-guided, filter-wheel mono rigs. The amount of skill, time, and dedication that goes into that is awe-inspiring. I’m also even more appreciative of how much smart telescopes bring to the table. My Seestars combine optics, imaging, focusing, a mount, a dew heater, a filter wheel, and a Wi-Fi-enabled computer, along with good planning software, live stacking, and basic editing, all for a price lower than basically any single component listed above.

timelapseA timelapse of conditions in my backyard during the capture.

I have a lot to do now :) I have a long to-do list of practices to improve my traditional workflow: power and cable management, better understanding balance, dew mitigation, and incorporating my new, secondhand Celestron 5SE. I am also hard at work evolving https://astroguide.space to better handle traditional equipment; and, of course, I’m using it to plan my next month’s worth of captures to take advantage of the amazing capabilities this new gear provides.

Companion notes

A Continent in Smoke

This is the North America Nebula (NGC 7000) rendered from oxygen, hydrogen, and sulfur data in a modified OHS palette. As I worked with the data, its colors began to resemble something closer to home: smoke filled clouds billowing from uncontrollable flames.

Over the past week, wildfires across Canada have threatened communities, displaced people and wildlife, and sent hazardous smoke across much of the continent. Hundreds of miles from the flames, skies dimmed, visibility collapsed, and air many take for granted became dangerous to breathe.

Beneath a smoke-obscured sky, this image began to take on a different meaning for me. There is an elemental connection here: the O, H, and S channels captured from this nebula are the same oxygen, hydrogen, and sulfur involved in wildfires.

In the nebula, these elements glow after being energized by radiation from nearby stars. In our forests, oxygen fuels combustion, and sulfur contributes to that acrid taste in the air.

The processes are different, but the ingredients belong to the same universe.

The fires are a painful reminder that our atmosphere connects us all—and that the environment supporting every community, every forest, and every view of the night sky is more fragile than it can seem.

My thoughts are with the people and ecosystems affected, and with those working to protect them.

background

this was not caused by one single Canadian forest fire- it came from a broad outbreak of fires, with the smoke affecting the Northeast originating especially from northern and northwestern Ontario, alongside fires farther west in Manitoba and Saskatchewan.

As of July 9, Canada reported 796 active wildfires, including 60 out-of-control fires receiving a full response. Officials expected July’s greatest fire danger around northern Manitoba, the Hudson Bay region, northern Ontario, and Quebec. By midweek, news reporting placed the national count above 800 active fires. 🍁 Public Safety Canada reported 796 active wildfires nationwide

Several things happened together:

Numerous new fires appeared in northwestern Ontario, including around Sioux Lookout, Thunder Bay, Lake Nipigon, Armstrong, and Wabakimi. Ontario reported 26 new fires in its Northwest Region on July 14 alone. The province had recorded 453 fires for the year by then, compared with a ten-year average of 312 at the same point. Ontario forest-fire update
A large, persistent smoke plume moved south and southeast through the Great Lakes, Toronto, New York, New England, and portions of the Mid-Atlantic. Toronto briefly reached the highest-risk category on Canada’s Air Quality Health Index, while unhealthy-air alerts spread across the northeastern United States.
The worst visibility occurred when that smoke mixed downward into the air near the surface. That produces the gray, yellow, or orange haze you can actually see—not merely a thin plume high in the atmosphere. Environment Canada specifically warned of “very poor air quality and reduced visibility” from northwestern Ontario smoke and noted that conditions could change dramatically from hour to hour.Environment Canada air-quality warning

For the northeastern U.S., the timing was roughly:

Smoke intensified around July 14–17.
Parts of the Great Lakes, Northeast, and Mid-Atlantic experienced unhealthy air, with some 115 million people potentially exposed.
Rain and thunderstorms on July 18 helped disperse or wash out some of the near-surface smoke. Conditions have consequently improved in much of New England, although residual haze and locally elevated particulate levels remain possible. Reuters, Connecticut air-quality update

Companion notes

Wizard Nebula, captured in the SHO Hubble palette.

The Wizard Nebula sits within the same local spiral structure of the Milky Way that our own Solar System occupies — an area called the Orion Spur, one of the smaller arms threading between the galaxy’s larger spirals. At different times of year, Earth’s orbit gives us completely different views through the plane of the galaxy. Over the coming months, our night sky shifts toward the direction of the galactic core. This image combines roughly 6 hours of hydrogen-alpha with 3 hours of sulfur data, revealing dense gas and dust being sculpted by radiation from newly formed stars inside one of those active stellar nurseries. Captured from my backyard in New Jersey with the Seestars S50 and S30 Pro, and dual narrowband filters.

Bubble Nebula in multiple palettes

These aren’t three artistic interpretations of the same image. They’re three different ways of visualizing the chemistry of the nebula.

palette	red	green	blue
HOS	hydrogen α	Oxygen	Sulfur
OSS	Oxygen	Sulfur	Sulfur
SHO	Sulfur	Hydrogen α	Oxygen

Notice what doesn’t change: No matter how the channels are mapped, this region is overwhelmingly dominated by hydrogen and oxygen. Sulfur is present, but only in relatively small amounts. In the HOS image it’s barely visible as hints of blue, and in the OSS image it contributes very little to the red oxygen signal. Even the classic SHO “Hubble palette,” which often produces rich golds and teals, is overwhelmingly blue here because there simply isn’t much sulfur to display.

To me, that’s the fascinating part. The colors aren’t telling us what the nebula looks like—they’re helping us understand what it’s made of.

The Bubble Nebula is another stellar nursery, but unlike the Heart, Soul, or North America Nebulae, the most obvious feature isn’t the cloud itself—it’s how a single massive star has begun reshaping that cloud.

The central star is a very hot, relatively young O-type star. While our Sun is 4.6 billion years old, this star is only about 2–4 million years old. The bubble itself is even younger; only a few hundred thousand years old. During that time, the star’s stellar winds having been carving the bubble out of it’s surrounding cloud.

Over the next few million years, the star will exhaust its fuel, leave the main sequence, and likely end its life as a supernova. When that happens, the Bubble Nebula will be reshaped once again. The resulting shock waves will create conditions that produce much stronger SII emission, making this region look dramatically different than it does today.

Companion notes

When we look toward Cassiopeia on a clear autumn night, we’re looking beyond our own local neighborhood of the Milky Way.

About 7,500 light-years away lies one of our galaxy’s great stellar nurseries: a vast molecular cloud where stars have been forming for millions of years. We know its brightest regions as the Heart Nebula (IC 1805) and the Soul Nebula (IC 1848), though nature never drew a boundary between them. Together they form a single star-forming complex spanning hundreds of light-years across the Perseus Arm of our galaxy.

Region	Catalog identity	What it contributes
Heart Nebula	IC 1805	A bright emission nebula shaped by young massive stars and dark dust lanes.
Soul Nebula	IC 1848	A neighboring emission region in the same broad star-forming landscape.
Double Cluster	NGC 869 and NGC 884	A nearby pair of brilliant young open clusters in the same Perseus Arm direction.

The names “Heart” and “Soul” are ours. The physics is timeless.

Heart NebulaA closer view of the Heart Nebula, where young stars and dark dust lanes carve structure into the surrounding hydrogen cloud.

At the center of the Heart lies Melotte 15, a young open cluster only about two or three million years old. The most massive stars in the cluster are dozens of times more massive than our Sun. Their ultraviolet radiation ionizes the surrounding hydrogen, causing the nebula to glow, while powerful stellar winds slowly sculpt the cloud into pillars, cavities, and dark dust lanes.

The stars are already changing the cloud that created them.

Those same stars will also determine the Heart Nebula’s future. Within a few million years, the most massive among them will exhaust their fuel and explode as supernovae. Their explosions will scatter newly forged heavy elements throughout the surrounding cloud, enriching the next generation of stars and planets.

Soul NebulaA closer view of the Soul Nebula, where several pockets of young stars illuminate and reshape the surrounding cloud.

While the Heart often draws the attention, the neighboring Soul Nebula tells the same story from a different perspective. Rather than being dominated by a single young cluster, the Soul contains multiple pockets of ongoing star formation spread throughout its vast cloud. Like the Heart, it is only a few million years into its current chapter—a fleeting moment in the life of a molecular cloud. Together, the two nebulae span hundreds of light-years across the Perseus Arm, quietly converting cold hydrogen gas into the next generation of stars.

The Heart and Soul Nebulae are not permanent, fixed celestial objects. they are one moment in a much longer story.

Just beyond the Heart and Soul lies another remarkable sight: the Double Cluster. At first glance it appears unrelated, two brilliant concentrations of stars floating against the background of the Milky Way. In reality, it is another nearby young stellar population, roughly the same distance from Earth as the Heart and Soul. Although it is not physically embedded within the glowing nebulae, it occupies the same broader region of the Perseus Arm, reminding us that this part of the galaxy has been producing stars on an enormous scale for millions of years.

Stars Around the HeartThe surrounding field puts the Heart Nebula back into its crowded stellar context: young clusters, foreground stars, and the broader Cassiopeia/Perseus Arm neighborhood all sharing the same sweep of sky.

Seen together, these objects transform our understanding of the night sky.

The Heart and Soul are regions within a much larger galactic landscape—a place where giant molecular clouds collapse, young clusters ignite, stellar winds reshape their birthplace, and future supernovae prepare the raw material for another cycle of creation.

The colors in this image trace hydrogen and oxygen, revealing where radiation from young stars is energizing the surrounding gas. Hidden within those clouds are countless other elements—carbon, silicon, iron, calcium—created by generations of stars that lived and died long before the Heart Nebula existed. Those same elements will one day become part of new stars, new planets, and perhaps new life.

Every atom in our own hearts followed a similar journey.

Long before Earth formed, those atoms drifted through clouds like these. They were forged inside ancient stars, scattered across the galaxy, gathered into new molecular clouds, and eventually incorporated into the Sun, the Earth, and every living thing.

The Heart Nebula reminds us that stellar nurseries are more than beautiful clouds. They are the places where galaxies renew themselves.

We are not simply looking at where stars are born.

We are looking at one chapter in the story of how the universe became capable of looking back at itself.

We are the Hearts and Souls of the Milky Way.

Companion notes

Pacman Nebula in HOO and SHO Palettes

This is the Pacman Nebula (NGC 281), shown in both HOO and SHO palettes. The HOO image is processed from 3.5 hours of Optolong L-eXtreme dual-narrowband HA/OIII data, and the SHO image adds 4 hours of SII/OIII data captured with the SVBONY SV220.

This isn’t just an aesthetic difference; the additional color and texture in the SHO image reveal more information about the star formation processes happening across this huge region of space.

This is what Capture Studio in AstroGuide was built for. The HOO image is great on its own, and it’s close to what we can capture when we “point and shoot” our Seestars at NGC 281. Capture Studio helped me understand that there was more to see and learn from this subject by adding additional channel data.

Those extra hours didn’t just produce a different color palette; they revealed subtle structures and relationships within the nebula that I never would have seen with just the HOO data.

That’s exactly the kind of question I’m building AstroGuide to answer: not just what to image, but how to get the most out of it.

Stacking and Cleanup Process

All stacking and post processing was done in Siril, often using the Workflow Companion script produced by DeepSpaceAstro.

Stacking
- Tower stacking: I started by stacking the L-eXtreme and SV220 data separately. I had 3 sessions of LX and 4 sessions of SV, each around 30-90 minutes. Each session was stacked using the Naztronomy scripts, with 1.5x/.8 drizzle, stars/BG rejection filters, and noise-weighted stacking.
- Cleanup: Each individual session was then cropped, background removed, and color corrected with SPCC.
- Masters: The sessions for each filter were then stacked together; the SV and LX sessions were stacked into SV and LX masters.
- Standardization: I created a sequence with the 2 masters, then plate-solved and registered the sequence so the masters would be aligned.
- Sequence operations: I could then perform “batch” operations on the masters together:
  - Deconvolution/aberration removal
  - Background removal
  - SPCC
  - StarNet star removal
  - SCUNet denoise
SHO construction: At this point, I had 2 properly aligned and cleaned masters from LX and SV.
- Extract channels
  - Pull HA (red), OIII (blue + green), and luminance from starless LX
  - Pull SII (red) and OIII (blue + green) from starless SV
- PixelMath
  - Enhance SII: SII becomes a 9:1 blend of the red channels from SV and LX, subtracting a portion of the LX green channel.
  - Soften HA: The HA from LX is very dominant, so I soften it by subtracting SV channels.
  - Aggregate OIII: Combine the OIII from both B and G channels from SV and LX.
- RGB recombination
  - Combine SII, HA, and OIII channels with the luminance layer
HOO/SHO finishing
- For both the recombined SHO image and the HOO image (starless from LX), I performed basic post-processing:
  - Statistical stretch
  - Additional tweaks with SCUNet denoise
  - Starless color grading with VeraLux Curves/Vectra
  - Star recombination
  - Cosmic Clarity sharpen
  - Final grading tweaks

Companion notes

Lagoon Nebula + Trifid Nebula

Two very different nebulae sharing the same region of sky. The Lagoon Nebula is a massive star-forming region filled with glowing hydrogen gas and dense dust lanes, while the Trifid combines emission, reflection, and dark dust in a single object — one of the few regions where all three are so clearly visible together. The red comes from hydrogen emission, the blue from reflected starlight, and the dark lanes are dense dust cutting through the center — giving the nebula its distinctive “three-lobed” structure. Also included in this frame is Webb’s Cross, M21- a simple alignment of stars that just happens to form a recognizable pattern from our point of view.

Capturing all of that together calls for a broadband filter like the L-Pro, which passes key emission lines and starlight while blocking much of the surrounding light pollution — improving signal-to-noise and letting more detail come through in less total integration time. This was captured in about 75 minutes from my backyard in New Jersey (Bortle ~4–5), with the moon up — a good example of what’s still possible under less-than-ideal conditions with the right target and filter choice.

Companion notes

Trifid Nebula and Webb’s Cross

Not all patterns in the night sky come from the same place.

The Trifid Nebula is shaped by physics; a complex region where gas and dust interact, forming new stars while being carved apart by radiation.

The glowing red comes from hydrogen gas, the blue from reflected starlight, and the dark lanes are dense dust cutting through the center, giving it its distinctive “three-lobed” appearance.

Nearby, Webb’s Cross is something entirely different; a simple alignment of stars that just happens to form a recognizable pattern from our point of view.

One is a real physical structure evolving over millions of years. The other is a coincidence of perspective… a reminder that not everything we see in the sky is actually connected.

Captured from my backyard in New Jersey (Bortle 5).
