Corwin's Notes
=====
NGC 1727 is actually a group of three HII regions and their associated stars.
JH's size, "3 arcmin long, 90 arcsec broad" makes clear what he saw, so the
position that I've estimated on the DSS refers to all three patches. Most of
the other positions refer to only the northwestern of the three.

NGC 1727
18" (7/10/05 - Magellan Observatory, Australia): fairly bright, fairly large, irregular patch, ~2.5'x1.5', with at least a half-dozen stars mag 13 stars resolved. This LMC cluster with nebulosity responds well to a UHC filter at 128x. A small extension is visible to the southeast (KMHK 187 = LMC-N79D) increasing the size to ~3.5'x1.5'. In a group with NGC 1722 4' SW and NGC 1712 7.5' SW. Located 4' N of mag 8.5 HD 31722. This is a very young cluster or association (LH 2) with an unevolved main sequence similar to nearby NGC 1722.
18" (7/9/02 - Magellan Observatory, Australia): at 128x and UHC filter this is a fairly large elongated patch of nebulosity, ~3.5' diameter with a group of mag 12-13 stars superimposed. A smaller detached piece of nebulous haze, ~1' diameter, is close SE. This is the 3rd (and 4th) in a chain of objects with NGC 1722 4.5' SW and NGC 1712 8' SW. A mag 8.5 star (HD 31722) is 4' SSE.
