A face-on grand-design spiral in Ursa Major, roughly 21 million light-years away. M101's arms unwind from a bright core in nearly perfect symmetry — star-forming H II regions stipple the disk, and the wider field picks up a few satellite galaxies and faint background fuzz.
Captured from the backyard in broadband: no narrowband blend, just the natural color of ancient starlight stacked into one frame.
When this light left the Pinwheel
Every photon in this image began its journey when M101 was already as it appears tonight — a mature spiral — but Earth was a different planet.
At a distance of about 21 million light-years, the light that reached my camera in left M101 around , deep in the . On Earth at that moment:
Grasslands were spreading across continents; C₄ grasses were on the rise and reshaping ecosystems.
Early apes such as Proconsul climbed trees in East Africa. The human lineage was still millions of years in the future.
The Mediterranean looked nothing like today's sea — broad land bridges and shifting basins still separated Europe from Africa.
Megalodon ruled the oceans. The Himalayas and Rockies were still actively growing taller.
Global climate ran warmer than today, with forests reaching far higher latitudes than they do now.
The galaxy in the frame is a time capsule. The backyard, the mount, and the sensor are the receiving end of a message that has been in transit since before the Grand Canyon finished cutting downward.
By the numbers (integration set)
A few facts from the M 101 integration set behind this image:
108 light frames at 300 seconds each — about 9 hours of total exposure, gathered across two runs (June 13–14 and June 16–17, 2026).
Calibration library: 80 bias, 40 dark, and 50 flat frames — roughly 2.4× as many calibration frames as lights.
Sensor held near −10 °C through the marathon; filenames record gain 100, Bin 1.
The set weighs in at 446 files / ~60 GB, including two stacked intermediates (stack-1 and stack-2) before the final export.
M101 itself spans about 170,000 light-years — nearly twice the Milky Way's diameter — making it one of the largest and brightest spirals in the Messier catalog.
If you're counting photons: each 50 MB frame is a small brick in a very large wall of light that crossed intergalactic space for longer than hominins have existed.

The target
Say hello to M106 (NGC 4258), a big, bright spiral galaxy sprawling across the little constellation Canes Venatici — the Hunting Dogs. It spans roughly 135,000 light-years, a touch wider than our own Milky Way, and it's got a secret: its core is active. A supermassive black hole weighing around 40 million Suns is busy feeding at the center, and the leftovers blast outward as jets. Those jets light up a pair of ghostly "anomalous arms" — extra spiral arms made not of stars but of superheated, glowing gas. Most galaxies show off their starlight; M106 also glows with the exhaust of its own black hole.
Distance and light
M106 sits about 23.5 million light-years away. Here's the fun part: it's one of the most precisely measured galaxies in the entire universe. A ring of water megamasers — naturally occurring cosmic lasers — orbits its central black hole, and tracking their motion lets astronomers measure the distance geometrically, no guesswork required. That makes M106 a key rung on the "cosmic distance ladder" we use to size up everything farther out.
When this light left M106
The photons that just landed on my sensor began their trip about 23.5 million years ago — the dawn of the Miocene epoch. Back on Earth: no humans, no hominins, not even close. Apes were just hitting their stride across Africa and Eurasia, grasslands were spreading and filling up with the first big herds of grazers, and kelp forests were taking root in the oceans. This light has been crossing the void since before our family tree had even branched off.
The capture
About 3.6 hours of integration — 72 × 180-second subs shot over three nights in May 2026 at gain 100. Calibrated with matched darks, flats, and biases, captured on a ZWO ASI2600MC riding a ZWO AM5N mount, and processed in PixInsight.
GALAXY
A few weeks ago I picked a random spot in the sky and found NGC 3184 The Little Pinwheel.
This image is roughly 5 hours of integration time, 120s exposures. My Redcat 51 is perfect for big objects like M31 Andromeda Galaxy but the focal length is too short for NGC 3184. However, if you Inspect the image and zoom you'll see it still has decent detail.
Fun fact about this image - NGC 3184 is 40 MILLION light years away. When the light leaving NGC 3184 started its trip to my telescope, Earth was in the Eocene. A few cool things about Earth ~40 million years ago:
There were no humans.
There weren’t even hominins yet.
Our ancestors at that point were very early small primates / proto-primates on the mammal side of the tree.

This proximity means that every observer on Earth experiences the Moon's light almost instantaneously, connecting us directly to its surface with each gaze upward into the night sky.
Deep time
The Moon's surface is approximately 4.5 billion years old, a timeline that lines up closely with the formation of the solar system itself. This makes the Moon a significant object for understanding the early years of our cosmic neighborhood. The majority of its dominant surface features were shaped during the heavy bombardment period, which occurred around 4 to 4.1 billion years ago. These figures are approximate and model-dependent, but they provide a sense of the Moon's long and storied existence in relation to our universe, which is about 13.8 billion years old.
When this light began its journey
As the photons that now illuminate our eyes began their journey from the Moon, life on Earth was entering a new and dynamic chapter. Imagine the world as it was around 4.5 billion years ago: a tumultuous place where volcanic activity shaped the land and the atmosphere was dense with gases. The oceans were beginning to form, and early microorganisms were starting to emerge in primordial waters. The light originating from the Moon, now a serene presence in today's night sky, witnessed those formative events as it traveled across the vastness of space, a silent testament to the evolution of our planet.
