Thanks again, everyone, for your feedback on this project! I have completed the processing. I enhanced the core color a bit & tweaked star reduction & some over-sharpening areas. A complete post on this effort can be seen here: cosgrovescosmos.com/projects… #astrophotography

They call Sh2-173 the Phantom of the Opera Nebula. I see a cosmic puppy! 🐶✨ 15h 46m of SHO + RGB with my AP155. Clouds, smoke, heavy dew—and a face worth the effort. Mask or puppy? cosgrovescosmos.com/projects… #Astrophotography

It looks a bit like the Tulip Nebula—but this is SH2-88, a rarely imaged stellar nursery in Vulpecula. 12.4 hrs of SHO data + RGB stars, revealing diffuse, compact & ultracompact regions of massive-star formation. Full project details: cosgrovescosmos.com/projects… #astrophotography

Thrilled to share that Amateur Astronomy Magazine featured two of my images in its Fall 2026 issue: Hickson 61 (“The Box”) and Sh2-140 (“The Hidden Nebula”). It’s an honor to see these deep-sky wonders in print! 🔭✨ #Astrophotography #Astronomy

The original image project post can be seen here: cosgrovescosmos.com/projects…

Very cool news: my SH2-140 image was selected as Astronomy Magazine’s Picture of the Day. The Hidden Nebula is a faint Cepheus target: the glowing edge of a dark star-forming cloud about 2,500–3,000 light-years away. astronomy.com/picture-of-the… #Astrophotography #Astronomy

Summer heat can be rough on observatory gear, especially the little fanless PCs running telescope piers. I added daytime-only fans & heat sinks to my MeLE Quieter 4C PCs, & disable them at night/during imaging. Watch: youtu.be/q7LWA3BLlWI #Astrophotography #MeLEQuieter4C

My image of M24, the Small Sagittarius Star Cloud, is included in the newly released 30th Anniversary Ed. of Circumstellar Habitable Zones, a NASA Ames conference volume w/ an intro by Carl Sagan. A real honor. Book: a.co/d/0icDWNiy The Image: cosgrovescosmos.com/projects…

NGC 7129, the Cosmic Rosebud Nebula, is live on Cosgrove’s Cosmos. ~14 hrs of LRGB on the AP155 reveal blue reflection nebulosity, dark dust, young stars, & nearby NGC 7142 in the same rich field. Project post w/processing details: cosgrovescosmos.com/projects… #astrophotography

NGC 7008, the Fetus Nebula, was a real small-target challenge. Only about 86 arcseconds across, it pushed my SCA260, local skies, & processing pretty hard. Final image: HOO+RGB stars, 10.5 hrs. Full project report: cosgrovescosmos.com/projects… #Astrophotography

SH2-140, the Hidden Nebula in Cepheus. 12.38h hrs of SHO narrowband + RGB stars, captured on my WO132 platform. Full project page: cosgrovescosmos.com/projects… #Astrophotography #Space #Astronomy #Nebula #Cepheus #SHO #PixInsight

The Sadr Region in Cygnus! 12.75 hr of SHO + RGB stars with the Askar FRA400 and ASI2600MM-Pro. Packed w/ emission nebulae, dark dust, young clusters, & Sadr glowing in the heart of Cygnus Zoom and pan for best effect! Full Details: cosgrovescosmos.com/projects… #astrophotography

New video: Introducing Astro Contrast Enhancer (ACE), a free PixInsight script for late-stage contrast refinement. Texture, Clarity, Dehaze, local edits - no need to leave PixInsight! Beta release: feedback wanted! Watch: youtu.be/89d1C4qY2ZA #astrophotography #PixInsight

New Free PixInsight Script: Astro Contrast Enhancer (ACE) ACE offers Texture, Clarity, Dehaze, protected local editing, real-time preview, & image protections. It’s in beta, free, requires PixInsight 1.9.4, & I’d love to hear what you think. Learn more: cosgrovescosmos.com/astro-co…

If you’re using Astro Color Mixer, this update video is for you! I cover Compact Mode, Difference Preview, better diagnostics, & dealing w/ low-saturation galaxy color w/o creating artifacts. Free PixInsight script. New video: youtu.be/VNTPoa-qQPc #PixInsight #AstroImaging

Astro Color Mixer v0.9.7.10-beta is out! What's new: Compact Screen Mode for smaller-screen environments + Standard layout for larger displays. Same color tools, smaller footprint! Free PixInsight script: cosgrovescosmos.com/astro-co… #PixInsight #Astrophotography #AstroImaging

Spectral response matters in astrophotography. But how do your target, sky glow, light pollution, filters, sensor QE, & OSC Bayer response combine to create your image data? My Astro Spectral Explorer makes that hidden chain visible: cosgrovescosmos.com/astro-sp… #astrophotography

New Astro Color Mixer release: v0.9.7.8-beta. This update focuses on better feedback & controlled targeting. Free PixInsight script- Repository Details below: cosgrovescosmos.com/astro-co… #PixInsight #Astrophotography

Astro Color Mixer Video 2 is live. As promised... This one gets into the real power of the PixInsight script: selecting color bands, shaping Hue Radius/Feather, and using Range Masks to target brightness. youtu.be/xXGrZQV4rgs #Astrophotography #PixInsight

Better color control in PixInsight? I built Astro Color Mixer, a FREE PixInsight script for late-stage RGB color refinement in astrophotography. Currently in Beta - Feedback requested! Video 1: overview + first use: youtu.be/23xBVRW_ojE #PixInsight #Astrophotography

Not every deep-sky target is large and dramatic. Hickson 61, “The Box,” is tiny, faint, distant, and easy to overlook — but that is exactly what makes it fascinating. New imaging project: cosgrovescosmos.com/projects… #astrophotography
