IC 1396, commonly known as the Elephant's Trunk Nebula, is presented here as a dataset totaling 5.83 hours of integration time. The data was acquired over two nights from June 30 to July 1, 2025, using a Tecnosky OWL 90/540 telescope operating at 432mm focal length paired with a PlayerOne Artemis C PRO camera on a Celestron CGX mount. The capture consists of 70 frames through an Optolong L-Quad Enhance 2-inch filter, each exposed for 300 seconds. This emission nebula dataset is offered as a free download under CC BY-NC 4.0 license terms, permitting copying, modification and redistribution for non-commercial purposes. The narrowband-optimized filter emphasizes key emission lines within this star-forming region located in Cepheus.
