Oct 10, 2020 Waikoloa, HI (map)
20cm f/6 Newtonian, Cave Astrola @ 76x
Seeing: 6 Transparency: 6 Moon: 0%
Brilliant white, an 8th magnitude 4" companion not visible, 58 Aqr visible 20' southeast
The companion is cataloged in Tycho as TYC 5814-1593-2 with a 3.8" separation and 8.46 magnitude, oddly the companion does not appear in WDS or Gaia DR2, there is certianly some confusion here
