The Milky Way is our own galaxy, so we see it form the 'inside'. From a dark site it appears as a wide milky band across the night sky. However, it is dim, so any amount of light pollution can interfere with our view of it. For this reason many people have never really seen it properly. Kaitlyn's aim was to produce images that show broad views of parts of the Milky Way visible in the evening sky in late Fall.
Kaitlyn used a modified Canon EOS T7i DSLR camera with a 25 mm focal length lens to take images of different parts of the Milky Way. (This modification removed an internal filter that usually cuts out much of the very red end of the spectrum.) The camera was mounted on an iOptron Skyguider Pro mount that tracked the stars as they moved slowly across the sky. This allowed for 30 second long exposures without producing the star trails that would be apparent if a fixed tripod was used. Even though the observing site was relatively dark, some light pollution from nearby towns was still evident, so a dedicated light pollution (LP) filter was mounted on the front of the camera lens to reduce its effects.
Between 17 and 24 exposures of 30 seconds each were recorded for each field of view. These exposures were then 'stacked' and processed with SiriL. This is a software package dedicated to pre-process astrophotography images, and can then also be used to edit the final image.
