Optimum magnification for a telescope with observations of M88, depending on the aperture of the telescope (D), is about D/6-D/3. Higher magnifications of course add details, but lead to a strong drop in the brightness of the image, making it difficult to observe.

The best month for observing M88 is May. At this time, the object is at midnight near its highest point in the sky, that is, it is less affected by light from the lanterns and atmospheric distortions.

For observers in the northern latitudes:the night sky in May is no longer very dark, so try also to observe M88 in April.
Of course, in April the object is at midnight not at its highest point, whichprovides the least exposure and atmospheric distortion. But, the darkness of the April sky greatly increases the contrast.The farther south the location of your observation is located, the darker the summer sky will be.
