Here is an image with a 8 degree field of view centered approximately on IC 4601. It includes IC 4592 and IC 4604. I have presented the image conventionally with North up, but when inverted you can see that IC 4592 looks like the so called Blue Horse head. The Globular Cluster M80 is there too, but at this image scale and exposure length, it just looks like a bright star.
