Hi all, I just want to inform you that I've started to build a nebula outlines catalog based on OpenNGC nebulae filtered by major axis >= 1 arcmin. I've uploaded a first, small batch of nebulae outlines with a Catgen catalog (text mode) ready to be imported in Skychart: https://github.com/mattiaverga/OpenNGC/tree/outlines/outlines Details about how the catalog is made are available in the metodology.txt file. I'd be glad to know your opinion and suggestions about that.
