Computing Life

A mathematical approach to narrowband color synthesis - using linear algebra and matrix transformation to map H/S/O channels to custom RGB colors, enabling precise control over saturation and aesthetic palettes beyond standard SHO.

用线性代数实现窄带自定义调色：选取喜欢的颜色获取RGB值，通过矩阵变换将HSO通道投影到新色彩空间，实现饱和度可控的个性化调色盘。

深空技巧应用于星野摄影：PixInsight可控拉伸、校准场去除暗角、长焦接片提升星点质量、大光圈下窄带滤镜带宽偏移问题及前置滤镜解决方案。

Deep sky techniques for wide-field astrophotography: controlled stretching in PixInsight, calibration frames for vignetting removal, telephoto mosaics for better stars, and bandwidth shift issues with narrowband filters at wide apertures.
