Comment : Desperately seeking interesting objects. I found one more galaxy cluster, centered the camera around the galaxy IC 4020, a small and weak galaxy. To find what's there I need some help from a plate solving IC 4020 plate solved. The bright star near center belongs to the constellation Canes Venatici.
