Deep-Sky 100
Messier objects are primer Deep-Sky objects, but I do not like galaxies near Virgo. They are only small dark haze through small telescope.
I have not looked all Messier objects, but The Double Cluster in Perseus or North America nebula is beautiful and wonderful.
Now, I listed 100 Deep-Sky objects that we can look from northern hemisphere. containing several challenging objects like Cat's eye nebula.
Plese try Deep-Sky 100 Objects.
