Description

The data for this LRGB image are from the Moana Project (https://erellaz.com/moana/open-datasets/m51-the-whirlpool-galaxy/)—approximately 11.3 hours total exposure for RGB and 3.8 hours of Ha.  The imaging system is described here (https://erellaz.com/moana/).  The Ha was added to the RGB using the Hagen method (https://www.nightphotons.com/guides/advanced-narrowband-combination).  A super luminance was prepared by combining all the data and this was used to form the LRGB image.  Processing utilized Pixinsight with minor adjustments to the image with Photoshop.  GraXpert AI was used to remove gradients.
