M8

	Diffuse Nebula NGC 6523 Sagittarius 18H 3.8m -24° 23' Magnitude: 3.0 Size: 90' × 40' Distance: 5,200 light-years

	Skill Level M8 is one of the brightest nebulae in the sky. The only problem is capturing a large enough field of view.

	Best Month Northern Hemisphere observers never get a chance to see M8 high in the sky. Your best bet is to capture it in August, when M8 is at its highest point.

$Refractors$	Recommended Equipment M8 is a large nebula; use a short focal length telescope such as a small refractor. A medium-sized rich-field Newtonian might also be appropriate if you have a camera with a wide field of view (or want to capture a mosaic).
