Every target with a real checkpoint, run through stack + denoise, sorted newest-imaged first. Sub counts, hours, and last-sub date are read directly off the raw FITS filenames, not estimated. Click any thumbnail for the full-resolution stack. Regenerated automatically every day.
M33 is well framed and shows detailed spiral arms, blue star-forming knots, dark dust lanes and a pink HII region (NGC 604) at lower left, with tight round stars and a clean dark background.
The Lagoon Nebula is well framed, with a bright core, red Ha filaments and dark dust lanes, tight round stars across a clean dark background, and no obvious gradients or tracking problems.
M74 is centered with visible spiral arms and a bright core, but the frame has heavy diagonal color-mottled background streaks, a bright corner and edge gradients, and the galaxy is small and soft for 18.9 hours of data.
The Western Veil is cleanly framed, with sharp teal OIII filaments, fainter red Hα wisps, pinpoint stars across the field and the bright star 52 Cygni near the center, plus a slightly bright, uneven strip along the bottom edge.
The Cocoon Nebula sits centered as a clean salmon-pink emission glow with a visible dark lane and a faint blue halo, and the star field around it is dense and sharp. I see no obvious doubling, though there is a ragged strip along the bottom edge and some chroma speckle in the background.
The Omega/Swan Nebula is well centered, with a bright core, detailed filamentary structure, dark dust lanes, and the faint nebulosity to the lower right all showing. Stars are tight and round, the background is clean, and I see no obvious tracking or noise problems.
The frame is a dense star field with only faint, wispy green filaments of Veil nebulosity near the right edge (around y≈600 and y≈1250), so the target is present but very weak at 1.1 hours.
The Tulip Nebula shows up centered with orange-red emission, dark dust lanes and its bright core stars, over a dense, round-star Cygnus field, with only slight edge gradients at the bottom and right.
M101 is clearly resolved with spiral arms, a bright core and some HII knots, but the field has heavy blotchy color noise, a green cast, and stacking edge artifacts on the right and top, and the outer arms are faint for 12 hours of data.
The Pelican Nebula's ridge and dark dust lanes show clearly across the frame, with clean round stars and low noise. The only flaws are a faint color fringe along the left edge and a blue glow at the bottom.
The Iris Nebula is centered with a bright blue-teal reflection core around the central star, dark dust lanes to the right, and faint dusty structure in the surrounding field, all with tight, well-formed stars and clean background.
The Crescent Nebula sits near the center with clear orange-red filamentary shell structure and a bright southern arc, against a dense, round-star Cygnus field with a noisy but even background.
M31's bright core and extended halo are cleanly framed, with detailed dust lanes along the right side, M32 resolved above the core, and round, tight stars on a clean dark background.
The frame is mostly a dense star field with dark dust lanes and a faint reddish emission edge at the far top-left, but none of the bright North America or Wall emission nebula you'd expect from 2.5 hours on NGC 7000, so the framing may be off-target or the pointing wrong.
M51 is clearly resolved with spiral arms, the companion NGC 5195, and faint tidal tails against a clean dark background with tight round stars. The only flaws are a bright gradient along the top edge and some blotchy, hard-edged halo around the galaxy pair.
The frame is a plain star field with a few faint background galaxies and no visible comet or nebulosity at or near the center, despite 5.1 hours of integration, and there's a noisy, misregistered strip along the right edge. That suggests the stack was registered on stars, which would smear out a moving comet, or the pointing was off.
At only 0.3 hours, this frame is clean and well-pointed, with the Whale Galaxy (NGC 4631) and its companion at right and the Hockey Stick (NGC 4656) at upper left, but the background is still noisy and the faint outer structure hasn't built up yet.
After 7.8 hours the frame shows only a sparse star field with two bright stars and no visible reflection nebulosity around M78, plus noisy, colour-speckled stacking borders along the top and left edges, which suggests a mis-pointed or badly registered stack.
M82 shows as a bright, elongated edge-on galaxy with M81's spiral arms visible at the top edge, and the stars are round and sharp. M82's disk is smooth with no visible dust lanes or outflow filaments, and M81 is cropped at the frame edge, so it is a real but shallow result.
At only 0.3 hours, the frame is mostly a star field with faint red filaments in the upper right and a brighter arc of IC443 at the lower left edge, so the target is off-center and under-integrated.
The frame is a dense, uniform star field with no visible Pleiades bright-star grouping and no blue reflection nebulosity, but at only 0.2 hours of integration that is too little data to say whether the pointing is wrong.
The Orion Nebula is well framed with fine dust lanes and pink-red filaments, and the Running Man nebula shows at the bottom. Stars are sharp and the background is clean. The core is blown out to white, which is common for M42.
The Horsehead is clearly resolved against the red IC434 emission, with the blue reflection nebula NGC 2023 and the Flame Nebula visible at the bottom. Stars are round and the field is well framed, with only some noise along the right edge.
The Crab Nebula sits clearly centered as a bright, compact blob with some faint internal mottling, but it's small and soft in a dense, clean star field, and there's no filament detail yet at 0.9 hours.
