Planetary nebula M57
Planetary nebula M57 or Ring is in the constellation Lyra (Lyr).
Equatorial coordinates (epoch J2000):
Visual magnitude: 8,8m
Optimum magnification for a telescope with observations of M57, depending on the aperture of the telescope (D), is about 50х-2D. 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 M57 is July. 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 nights in July are still quite light, so it makes sense to try to observe M57 also in August.
