https://www.skyandtelescope.com/sky-and-telescope-magazine/inside-october-2018-issue/ 

In the October 2018 issue of Sky & Telescope, we explore our galactic neighborhood. Learn about the cosmic void next door that acts like a gravitational hill, helping galaxies to slide together. Hear the whole story about ʻOumuamua — how did scientists find it, what is it, and why are we sure that it came from interstellar space? Our tourist's guide to the autumn sky selects several excellent objects to observe on your nightly journey. And, for the astrophotographers out there, we have a selection of lesser known imaging targets near showpiece objects. Discover the story of the Great Melbourne Telescope and how a team of amateur astronomers are working with museum conservators to restore the telescope using many of its original parts. Check out our observing picks for the month, learn about the hole in the Moon's magnetic field, and spot some beautiful planetaries! Make your own easy and effective light barriers. Plus, we review Meade's new mini astrograph. Enjoy these and other stories in the October 2018 issue of Sky & Telescope.
