GIMP: Crop, adjust curves to remove background sky glow, apply 1.50 Gaussian blur to enlarge stars

The Peiades Cluster (lower left), Jupiter (upper right) with passing Starlink satellite and the faint trail of a passing aircraft. The Moon is off-frame to the upper right and caused significant skyglow with the long exposure which necessitated cropping of the image. The background has been darkened and the stars enlarged via a Gaussian blur to show many more of them. The original image was acquired from a heavily light-polluted area, just above streetlights
