This dataset captures Sh2-173, also known as the Phantom Nebula, through 30.4 hours of total integration time collected between September 2025 and May 2025. The imaging system paired an Askar 151PHQ telescope with a ZWO ASI2600MM Pro camera on an iOptron HAE69 mount. The data comprises narrowband exposures totaling 226 frames in H-alpha at 300 seconds each, 83 frames in SII at 300 seconds, and 32 frames in OIII at 300 seconds, supplemented by broadband RGB channels with 40 frames per filter at 60 seconds using Antlia 2-inch filters. All Antlia narrowband filters feature 3nm bandpasses for high spectral selectivity. The dataset is available as a free download under CC BY 4.0 license, permitting copying, modification and redistribution with appropriate attribution to the original author.
