About this image

I have added new data to the image, captured on February 7 and 8 with another configuration of the equipment used, getting more detail with data augmentation

The two channels captured with the L-eXtreme filter, Halpha and OIII, have been expressed in red and blue, respectively, achieving greater contrast in the nebula's filamentary structures
