NGC 6590 in the Heart of the Milky Way
This is an interesting image for many reasons. First, the nebula itself is very diverse, with pink hydrogen emission as well as blue reflection areas. It’s convenient location right next to the Sagittarius star cloud offers a beautiful field of view on the right hand side of the image. Second, this image was captured under almost perfect skies in Fort Davis, TX, which allowed me to capture a very nice image with less than 1hr and 5min of data! And last, and purely by chance, I captured my first asteroid! The reason it appears rainbow colored is because it was moving as I changed filters from luminance, red, green, and then blue, allowing me to discern that it was moving to the right (relative to my imaging frame).
