This dataset captures LBN 408, a reflection nebula also known as the Little Iris, located in the constellation Cepheus. The target was imaged over the course of approximately one month from late August through the end of September 2024, accumulating just over 19 hours of total integration time. Data was gathered using a TS-130 APO refractor paired with an ASI294MM Pro monochrome camera on an AM5 mount.
The acquisition comprises 183 luminance frames at 180 seconds each, alongside 106 blue, 100 green, and 94 red filtered exposures at 120 seconds apiece, all captured through Antlia 1.25-inch filters. This LRGB dataset provides calibrated monochrome sub-exposures suitable for custom processing and color combination. The material is offered under a CC BY-NC 4.0 license as a one-time purchase at roughly $16.90, permitting copying, modification, and redistribution for non-commercial purposes.
