Two weeks ago I observed this pair under a SQM 21.3 sky with my 16". Here's my sketch and notes:

Arp-111.jpg

This is a very small and weak duo and it’s a challenge to split both galaxies. At 362x this is successful where NGC 5421A is the largest and brightest of the two and NGC 5421B can only be glimpsed with AV. The two reside in an oval glow and are perpendicular to a mag 15 star. The companion (CGCG 191-043) and elliptical loop however could not be seen.
