Cosgrove’s Cosmos Software Utilities
These are browser-based astrophotography tools I have built to support practical imaging work. They are designed to help summarize equipment, visualize telescope platforms, and compare imaging systems in a more structured and useful way.
Current Utilities
These are the tools currently available on the site. More will be coming…
Color Refinement Tool
Astro Color Mixer
A browser-based beta tool for refining hue, saturation, and luminance in stretched RGB astrophotography images, with astro-focused color regions, Range Mask targeting, histogram, polar plot, and probe feedback.
Open Utility
Exposure Tool
Astro Exposure Explorer
Helps astrophotographers think through subexposure choices by balancing read noise, sky background, signal strength, saturation risk, and practical imaging conditions.
Open Utility
Comparison Tool
Astro System Compare
Compares astrophotography systems side by side to reveal differences in scale, sampling, field coverage, and broader imaging tradeoffs.
Open Utility
Profile Utility
Astrophotographer Profile Summary
Builds a concise, organized summary of an astrophotographer’s equipment, platforms, workflow, and imaging approach in a format that is easier to review and share.
Open Utility
Platform Builder
Platform Card Builder
Creates polished telescope platform cards that combine equipment details with computed values such as focal ratio, image scale, field of view, and guide relationships.
