Stop Eyeballing: Estimating Filter SNR in Astrophotography

Описание: This video introduces an upgraded cross-section tool that estimates the relative signal to noise ratio (SNR) of images. We explain the importance of SNR for narrowband imaging, emphasizing that better SNR leads to better results with less integration time, especially when working with different filters. This tool is a great resource for astrophotography, offering valuable tips and tricks for image processing and understanding dynamic range.
