This dataset captures NGC 3372, the Carina Nebula, one of the largest and brightest emission nebulae in the southern sky. The acquisition consists of 48 total frames gathered on 2026-04-11 using a Samyang 135mm F2.0 ED UMC lens paired with a Toupteck 2600MM camera on an HEQ5 pro mount. The data includes 16 frames each through Antlia 4.5nm Ha, SII, and OIII narrowband filters, all at 60-second exposures, yielding 0.8 hours of total integration time.
This narrowband tricolor dataset enables mapping of ionized hydrogen, sulfur, and oxygen emissions within the nebula's complex structure. The 135mm focal length provides a wide field suitable for capturing the nebula's extensive boundaries.
