Jeff, I won't count this question, as it's just a friendly personal inquiry
. In fact, I wasn't involved, but then I hardly ever am. Most times, I just read. As I am not a professional, I rarely feel I have something to contribute.
Centaur, there has been a definite tendency to make the questions harder and harder and to use up more time for them (the thread started in June 2005). 20 questions is just one manifestation of this trend (and I have nothing against it), so splitting the thread is probably not worth the while.
I suggest y'all beat this one to death quickly now and then we move one. I will try to pose crisper questions when/if I get the chance next time...
So:
20 questions (yes-no) again: What is the pair of astronomical objects (i.e, two objects closely spaced on their own length scale) I am thinking of?
# 1: No, they are not within our own galaxy
# 2: No, they are not within our Local group of galaxies.
# 3: No, none of the constituent parts is what an amateur astronomer would consider "prominent".
# 4: Yes, the two objects are galaxies.
# 5: No, the galaxies do not have an informal name which is the name of an animal.
# 6: Yes, they are in the Northern celestial hemisphere
# 7: No, 'tis not a winter constellation
# 8: No, it is not a summer constellation as per
this list.
# 9: No, to my knowledge they are not members of Arp's Atlas of Peculiar Galaxies
#10: No, they are not in a circumpolar constellation (from Aachen).
#11: Yes, they are in a constellation named after a real animal.
#12: No, it is not a four-legged animal.
#13: Yes, it is in big ol' Serpens (one of them, that is).
(uncounted: No, I didn't discuss them when they were discussed on the parent sites)
#14: ...
