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

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 7158 is a triple star. It is precisely identified by Muller's note "* 9.5 PA = 40 deg, distance = 2.8 arcmin." Both Bigourdan and Howe found the object 0.6 minutes following a typically poor Leander McCormick position, and there it still is on the sky today.

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a galaxy. Their coded description reads USBOVAL.

Modern observations

Steve Coe

Steve Coe, using a 13" f/5.6, notes: "Is given as a triple star in NGC 2000. Sure enough, there is a a triple with two members about 9th mag and one 11th at this location. They are separated by about 30 arc seconds in a straight line at 100X. This multiple star system must have been included in the NGC because of its appearance at low power, using 60X this group is nebulous. It is marked as a galaxy on Uranometria 2000."
