Use these finders to locate the Arp targets discussed in the Going Deep column in the October 2021 issue.
In the October 2021 issue of Sky & Telescope, author Ivan Maly describes how to locate and observe a handful of peculiar galaxies that American astronomer Halton Arp first cataloged in 1966 in his Atlas of Peculiar Galaxies. Maly's selection are all well-placed in the autumn skies — you'll find them in southeastern Pisces and Cetus. We've collated finder charts here to guide the observer.
