ESA/Hubble
Collaboration active since 2005, with more than 1,000 completed images produced in connection with Hubble image processing work.

Software products and research initiatives for image-driven workflows.
DemaHub is the public portfolio for a focused set of software products and long-term projects spanning astronomical imaging, desktop viewing, data handling, and structured archival research, informed by work that transforms observatory data into public-facing imagery across major outreach environments.
3 product lines across imaging and scientific workflows
1 research project built as a long-term archival resource
More than 2,000 images completed across collaborations and independent production
Each product and project now lives as a self-contained landing page, with clearer hierarchy, stronger SEO structure, and a more consistent public presentation.
Selected collaborations
Long-running imaging work across institutional and independent contexts
The public portfolio sits on top of a substantial body of completed imaging work produced through collaborations and independent projects. In these collaborations, the work was carried out within Education and Public Outreach teams in the role of image processing specialist and data miner, with outputs intended for media, educators, publishers, and the general public. The figures below refer to completed images.
ESO
Collaboration active since 2007, with more than 400 completed images across European Southern Observatory-related work.
ESA/Webb
More recent collaboration involving the James Webb Space Telescope, with some 90 completed images.
NSF NOIRLab
Recent work connected to NOIRLab imaging and software activities, with more than 130 completed images.
Digitized Sky Survey
More than 400 completed images produced from Digitized Sky Survey material for independent work and projects connected to ESO, ESA, and NOIRLab.
Total body of work
More than 2,000 completed images across ESA/Hubble, ESO, ESA/Webb, NSF NOIRLab, and Digitized Sky Survey production.
Selected work
A small visual sample from the completed imaging record
The examples below are included as representative samples tied to the collaboration areas referenced above. They make the production record more legible than numbers alone.
ESA/Hubble
Crab Nebula
M1, produced for ESA/Hubble from an eight-frame Hubble Space Telescope mosaic acquired with WFPC2.
Hubble
NGC 3603
NGC 3603 from Hubble Space Telescope ACS data, part of the broader Hubble image-production record.
ESA/Webb
M74
M74, produced for ESA/Webb from James Webb Space Telescope observations acquired with MIRI.
ESO
M78
M78 in Orion, produced for ESO from Wide Field Imager data taken with the MPG/ESO 2.2-metre telescope at La Silla Observatory.
ESO
PN K1-22
Planetary nebula ESO 378-1, obtained at the Very Large Telescope with the FORS2 camera.
Products
A compact product portfolio with clear separation between offerings
The software section is intentionally narrow: each product addresses a specific imaging or FITS-related workflow and is presented as an independent destination.
Astronomy software
FITS Liberator 5
Cross-platform application for opening, visualizing, stretching, and exporting astronomical FITS files, including large scientific datasets.
Interactive stretch
Large datasets
TIFF export

FITS Packer
Windows desktop GUI for fpack and funpack, designed to make FITS compression and decompression more operationally accessible.
Batch runs
Drag and drop
Windows workflow

Research project
Stones of Venice
A separate research and cataloguing initiative documenting erratic stones, inscriptions, fragments, and reused stonework across Venice and its lagoon.
- Long-term cataloguing and field documentation
- Historical and naturalistic framing
- Positioned separately from the software portfolio
Focused
A deliberately small set of products with distinct positioning and dedicated landing pages.
Technical
Built around practical use cases in imaging, FITS handling, browsing, and compression.
Independent
Research work remains visible while staying structurally separate from the product catalogue.
