These include four globular clusters, the largest and the smallest planetary nebulas in the catalog, and a small oddity. Two of the objects are fairly easy in binoculars, while four others will require dark skies, patience, and keen eyes to find. M57 - This smallest planetary nebula in the Messier Catalog is the famous Ring nebula in the constellation Lyra. Low power telescope views show a very small blue/green disk, not much bigger than a star. Medium to high power will magnify the size of the nebula while leaving the surrounding stars the same size, confirming you have found it. Can be seen in binoculars as a faint star like point of light. M56 - Also in the constellation of Lyra we find our first globular cluster of the night. In a telescope look for a small round ball of light, slightly brighter in the center. This is a difficult binocular object appearing as a small fuzzy patch. M27 - Also known as the Dumbbell nebula, the largest planetary nebula in the Messier Catalog, M27 lies in the constellation Vulpecula. Fairly easy to see in binoculars as a small hazy patch. In small to medium scopes it appears as a rectangular patch of light. In large scopes it may even appear round in shape with a bright rectangular, or dumbbell shaped core. M71 - Lying in Sagitta, this globular cluster appears as a faint oval hazy patch of light in a telescope. This is a very difficult but possible binocular object, requiring dark skies and trained eyes. M30 - This globular cluster in Capricornus is tough but very possible to see in binoculars as a faint fuzzy star. Telescopes show a small fuzzy ball of light, bright in the center fading to the edges. M72 - This is a small faint globular cluster in Aquarius. Look for a faint oval patch of light, gradually brighter towards the middle. A very difficult binocular object. M73 - This asterism is located near M72 in Aquarius. In a low power telescope view it looks like a very small fuzzy patch of light at first glance. When stared at it reveals itself as a small collection of stars. Medium to high power shows the view best described by Messier "cluster of three or four stars...containing very little nebulosity".
