Another remarkable feature is the brightening of comets as they approach the central Sun with perhaps the brightening around the 21st January being the best of that year.

Identifying comets on a celestial sphere is perhaps enjoyable in its own way and seems to have a large following, however, to see the inner solar system and all the dynamics going on is far more satisfying for those who can make the adjustment.
Again, low hanging fruit for the first people to make correct judgments from orbital perspectives minus daily rotational effects.
I see nothing advantageous with observing the prograde/retrograde motion of the inner planets as opposed to observing the same motions of the outer planets - except that they occur more frequently for the inner planets.
