M82: 102mm Refractor vs Hubble Space Telescope
Photo description / processing
How the same object appears in an amateur 102mm refractor telescope versus Hubble. My favorite ionized hydrogen outflows from the center of galaxy M82. The Hubble image was taken in March 2006. Mine in March 2020. Exactly 14 years between the images.
