The social home for astrophotography and stargazing
TEZCATT is a social environment built for astrophotographers and stargazers. Publish night-sky photographs, build your profile, explore a location-aware sky map, and connect through groups and events.
Featured public NASA imagery. Usage guidelines
Tezcatt only receives basic profile details. You can also create an independent Tezcatt account below.
You can sign in with your username. Add email later if you want recovery and receipts.

Cosmic goods for the stargazing community
EXPLORE / SPATIAL CONTEXT
Reference geometry, populations and individual identities.
DISCOVER / PROVIDER CATALOG
Bounded NASA/JPL samples and NASA PDS dynamical families.
RESEARCH / INTERNAL TEST BETA
Precision celestial simulation, saved definitions and traceable reference comparison.
Checking server capabilities…
The dedicated workspace for bounded celestial simulation and provenance.
Minimal validated force hierarchy · 10 saved scenarios.
Expanded validated force hierarchy · 50 saved scenarios.
Both plans retain a one-hour / five-sample limit. Reference browsing remains available in the explorers.
Review test plansPublic charging disabled.
Select an admitted identity to configure a simulation.
Account-owned request definitions. Loading never starts a run.
Create, edit or archive definitionsGeometric reference and simulated states retain their own provenance. Display lighting and procedural shapes are illustrative. No navigation, resolved surface prediction, resource valuation or industrial certification is implied.
IMMERSIVE / DEVELOPMENT BOUNDARY
A separate space for immersive visualization development.
No new propagation runs here. Preview materials, camera movement and lighting are visualizations, not telescope imagery or measured rotation.
Observed optical — MEASURED: Hubble records calibrated electromagnetic radiation; optical brightness is not a baryonic-mass map.
X-ray emission — MEASURED: Chandra event counts trace projected X-ray surface brightness; cyan is false color and this is not a gas-mass map.
Thermal SZ — MEASURED by default: Bolocam native uK_CMB is shown with a signed blue–neutral–amber scale. Unfiltered means pipeline-filter effects were deconvolved, not raw data; large-scale noise is enhanced. The ~59″ beam remains the physical resolution. The selectable gNFW product is a MODEL.
Projected mass — INFERRED: Lensing constrains a model-dependent line-of-sight mass distribution, not a direct dark-matter detection. No subtraction residual, baryon fraction, gas mass, temperature fit, or 3D reconstruction is calculated.
