The Overlooked Objects Log (OOLog) is very similar to The Ultimate Messier Object Log, except it deals with the 45 objects in Brent Watson's excellent book, "Finder Charts of Overlooked Objects."
These objects include the Blue Snowball, Saturn Nebula, Owl Cluster, Veil Nebula, North American Nebula and other worthwhile sights. While many of these objects are beyond the reach of smaller scopes, some can be seen without a scope at all! (i.e., The North American Nebula.) And one object, the black hole Cygnus X-1 cannot be seen with any visual scope and is included as sort of a curiousity.
