This image by Roma Hdlaky ’22 was taken the night of 20th Sept 2020 at Haverford College.
Roma explains: “The Pelican nebula is a cloud of gas and dust. The Pelican nebula is extremely high in H-alpha which is prevalent with active star formation.
The blue [emission] in the center is produced by the H-alpha filter. OIII and SII filters were also used and stacked in this image, but were faint in comparison to H-alpha.”
