C/2025 R2 (SWAN) edges past Earth this October at ~0.26 AU, its green coma and 2-degree tail visible through binoculars. Discovered in September via SOHO/SWAN, it’s a long-period comet from the outer Solar System, now lighting up our dusk skies—and reminding us how rare and transient such cosmic intruders are.
M27, the Dumbbell Nebula, lies about 1,360 light-years away in Vulpecula. Through the Seestar S50, it glows in turquoise and crimson — the fading breath of a dying star. Its expanding gas shell, shaped like a dumbbell, reminds us that stellar endings are not destruction, but transformation into new cosmic beginnings.
NGC 891, the Silver Sliver Galaxy, lies 30 million light-years away in Andromeda. Seen edge-on, its dark dust lane divides a glowing river of stars — a near twin to our Milky Way. Through the Seestar S50, it reveals a galaxy’s elegant structure, suspended in silent, luminous equilibrium across the cosmos.
The Siril workflow involves stacking Seastar S50 data, removing green noise, using Grappert AI for background extraction, and Spectrophotometric color calibration. Stars are removed (StarNet) and the image is stretched using Generalized Hyperbolic Stretch. Final steps include star recomposition and sharpening.
The Sun, our nearest star, burns 150 million kilometers away — a vast fusion engine turning hydrogen into light and life. Captured with the Seestar S50, its shifting sunspots and fiery prominences reveal a dynamic star in constant motion, the heartbeat of our solar system and the source of all warmth.
NGC 6992, the Eastern Veil Nebula, lies 2,400 light-years away in Cygnus — a glowing remnant of a star that died millennia ago. Captured with the Seestar S50, its delicate red and blue filaments trace shock waves through interstellar gas, turning the memory of destruction into a masterpiece of light.
NGC 7331, a majestic spiral galaxy 40 million light-years away in Pegasus, mirrors our own Milky Way in form and scale. Captured with the Seestar S50, its glowing core and sweeping arms reveal a living galaxy beyond our own — a distant reflection of home shining across time and space.
NGC 281, the Pacman Nebula, lies 9,200 light-years away in Cassiopeia — a glowing nursery of young stars. Captured with the Seestar S50, its crimson gas and dark dust lanes reveal gravity and radiation at work, shaping new suns within dense clouds in the quiet arms of our Milky Way.
M74, the Phantom Galaxy, lies 32 million light-years away in Pisces — a near-perfect spiral seen face-on. Captured with the Seestar S50, its faint arms of newborn stars wind gracefully around a dense core, revealing the quiet architecture of a galaxy forming and fading across the vastness of time.
M16, the Eagle Nebula, soars 7,000 light-years away in Serpens — a vast cradle of creation. Captured with the Seestar S50, its glowing clouds and towering “Pillars of Creation” reveal where new stars are born, as light and gravity sculpt the raw dust of space into future suns and worlds.
