This dataset captures NGC 4258, also known as M106, a spiral galaxy in Canes Venatici. The collection spans 11.5 hours of total integration time, gathered between April 1 and April 22, 2019. Imaging was performed with an AG Optical 10-inch iDK F6.7 telescope paired with an FLI InterLine 8050 camera, mounted on an iOptron CEM60EC. The data comprises 69 frames across four channels using Astrodon Gen1 E-Series Tru-Balance filters: 36 luminance frames at 600 seconds each, 14 red frames, 11 green frames, and 8 blue frames, all at matching 600-second exposures. This LRGB dataset provides calibrated sub-exposures suitable for processing into a full-color image of this nearby active galaxy. The material is available under a CC BY-NC 4.0 license for approximately $5.90 as a one-time purchase, permitting non-commercial use, modification, and redistribution.
