Harrington's Cosmic Challenge as one list

[EmeraldHillsSkies]

Here's Phil Harrington's Cosmic Challenge from the book by the same name, written by Philip S Harrington, Cambridge University Press, 2011. In this list, we've included objects that Harrington included in his Appendix (table) beginning on page 450 of the book - as one unified list. Note that I used the "Brief note" field for a code that represented Harrington's numbering system. I numbered the categories 1 through 6, with 1 referring to naked eye ("Eye") and 6 referring to "monster scope" ("Mon"). I couldn't figure out how to list all the moon features. When targets were listed twice, I just made a notation of the second follow-up target in the "Brief note" field following the designation. Hope you can have as much fun with the list as I'm having!
