HOW TO FIND IT:
M88 is not that hard to spot, but there are no guide stars in the area. I still begin with 6 Coma as my starting point. I slowly scan the area shown on the chart.
Once you have found M88, slowly and carefully scan for M91.
WHAT TO LOOK FOR:
With M88, you will see a miniature Andromeda Galaxy. The nucleus is bright, and there is a varying amount of brightness around the edges hinting at its arm structures.
