Optimum magnification for a telescope with observations of M27, depending on the aperture of the telescope (D), is about D/4-D/2. 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 M27 is August. 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.
