Corwin's Notes
=====
NGC 2459 is a group of five stars. WH described it only as "Suspected. eF,
vS, lE", while JH said, "A l [sic] group of S sts which has a neb look, and
perhaps there may be neb among them. No other near" and "A S group of sts;
with attention counted 5 with power 320[X]; form a neb group 20 [arcsec]
diam".
No nebulosity was ever seen at Birr, so JH was pretty certain that the object
was only a small group of stars. Dreyer was sure enough that he made this
clear in note in the 1912 collection of WH's scientific papers.
Steve's Notes
=====
NGC 2459
17.5" (2/22/03): this very small group of 5 faint mag 14-15 stars within 30" was just resolved at 220x . At low power it appeared like a nebulous spot. Although this may be a multiple star, it's likely just a compact asterism.
