Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

Historical observations

William Herschel (c.1784)

Synonyms: H II-272

Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "Two, very close, not far from lying on a parallel to the declination. The following [NGC 742] smallest and most north." Dreyer notes: "Observed three times by H, but he only once saw it double. The following one is very slightly south of the preceding one." The NGC calls it "vF, vS, R, sbM, f or 2."

Birr Castle/Lord Rosse

An observer using the 72-inch f/8.8 speculum telescope at Birr Castle noted "Double nebula [NGC 741 & NGC 742]; the preceding one is pB, R, bM. The following one is smaller and fainter, and lbM."
