The thing with dark objects is, they require dark skies to be enjoyed. That's why I'm looking forward to next Saturday at the airfield. From home I can barely make out the coal sack most nights.
Another interesting dark object to add to your list is the Doodad in Musca. Supposedly a 3˚ long bino target I have never actually seen it myself.
Cheers
Steffen.
