Corwin's Notes
=====
NGC 1767 is one of a number of nebulae and clusters in the LMC that JH found
with a 5-inch refractor. Beginning on 2 November 1836 and continuing through
26 March 1837, JH worked across the Cloud in 34 different zones with his
refractor. He does not give us many details of his work on these zones, but
if we assume to zeroth order that he worked steadily on these, given that
there are 144 days between his beginning and end dates, that would allow him
4.24 days per zone. This would allow us to guess at the discovery dates --
or at least the years -- in which he discovered the objects. Since N1767 was
put into zone 9, it was probably one of the earlier objects found, so November
or December of 1836 is a reasonable guess as to its discovery date.

NGC 1767
18" (7/10/05 - Magellan Observatory, Australia): at 218x, this compact LMC cluster appeared bright, small, round, ~25" diameter, containing a very small bright core and an overall high surface brightness. Forms the western vertex of a triangle with NGC 1782 7.4' E and NGC 1772 9.5' SSE. Just 2' N, I noticed a very faint and small, round cluster, ~15" diameter (verified as Shapley-Lindsay 123). These clusters are part of the stellar association LH 8 and within LMC-N94, though no nebulosity was seen.
