At 37x both galaxies appeared together as oval brightening, whereby the brighter, northern NGC5427 was already visible as round, evenly bright, but faint nebula. NGC5426 was barely seen with averted vision. At 80x the galaxies were well separated. NGC5426 appeared slightly elongated and also evenly bright.
