- visible from Europe (at least from Canary Islands, 18 declination north)
- logged by me at least as "beautiful" or "interesting" over the years.
- visible with a 4 inch telescope and look good in it.
So in short, the list contains the best of the best (at least in my opinion) down to -50 declination. I'm sure there are many objects in the list that YOU disagree upon but it is simply a list made by guy who found these specific objects worth looking at. Down the line, I might add in more objects down to -90 declination and call it "Deep Sky 1000" if I ever get to see the deep southern sky in my lifetime.
