NGC 1736. JH's position is toward the middle of the western "lobe" of the nebula. This is where the brightest stars are located, including the "chief of which in the anterior part of the neb [was] taken." In the one sweep when he estimated the size of the nebula, though, he made it four arcmin long and 2.5 arcmin across, almost exactly what we seen on the short exposure DSS V-band plate.
The position I've adopted is more toward the intersection of the "lobes" and is more representative of the entire nebula.
John Herschel recorded it as "bright, round, resolvable."
Recorded in "Observations of the Southern Nebulae made with the Great Melbourne Telescope".
See the discussion of Lithograph M.3.21 for the details.
According to Henize (Catalogues of Hydrogen Alpha Emission Stars and Nebulae in the Magellanic Clouds, Astrophysical Journal Supplement 2, 1956, p315), his object LH N 120-8 is "Probably NGC 1736. The NGC description suits the object but the position is 1 minute in error." He notes that it measures 1.4' east-west and 1.9' north-south. It has a slightly irregular outline, is not elongated and has appreciable structure. Two 12.8 mag exciting stars are involved.
Lindsay, E. M. (1964) Some NGC objects in the Large Magellanic Cloud", IAJ, 6, 286-289. [1964IrAJ....6..286L]
"NGC position in error and should be 1m East where there is a bright round patch of nebulosity not listed in the NGC. This is H N8 and noted by Henize to be probably NGC 1736 with 1m error."
The RNGC (Sulentic and Tifft 1973) notes that this is a diffuse nebula in the LMC.
15cm - fairly br neb @ 80x, mod UHC and [OIII] enhancements. 195x: only two m13.5 *s plus a few others over 1' diam ~circ neb. BS, 12Nov1993, LCO.
