Corwin's Notes
=====
NGC 7143 is a zigzag line of five stars at JH's position. He suspected that
the object might be a nebulous double star, but the Birr Castle observers saw
no nebulosity here. Hence, Dreyer has a short note in the NGC saying that the
object is probably only a very faint double star. On the POSS1 and DSS,
however, the asterism is a striking object, and I can easily see why JH picked
it up while sweeping. His double star is probably the brighter northeastern
pair; Wolfgang's position applies to this pair.
Lord Rosse and his observers did talk about a small cluster in two of their
observations, however, and I'm a bit surprised that Dreyer did not include a
number in NGC for it.
Steve's Notes
=====
NGC 7143
18" (10/25/03): this is a faint, very close pair of mag 15 stars that was just resolved at 257x. At first glance at 215x, this pair appeared nebulous. Also, an easier distinctive pair of mag 14 stars is just 2' E. Located 28' SW of mag 5.1 14 Pegasi.
