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.

16-inch f/10 SCT (127x, 290x)

Hogg 11 word aangedui as 'n dowwe stringetjie 12magnitude sterretjies perfek in gelit wat oos uitloop vanaf die 8.3magnitude wit ster (HD97381).

'n Pragtige besige sterveld met Hogg10 en 11 skuins suid gelee vanaf NGC3572 wat ook in die aangduide sterveld gesien kan word.

Brent Archinal: The HD indentifactions of the center stars given here were obtained via the DSS. The positions and brightest sta (V) magnitudes are from SIMBAD. Note that for Hogg 11, the brightest star magnitude (8.3) is brighter than the listed total cluster V magnitude of 8.8 from Brian Skiff. Both of these objects are contained in Collinder 240. Collinder 240 32' x 23' scattering of stars. Its identity and the identity of NGC 3572 have sometimes been confused since he unfortunately labelled this large object "NGC 3572a" It includes y Carinae and the clusters NGC 3572 (called "NGC 3572b" by Collinder) Hogg 10, and Hogg 11. The position is that of the bright star HD 97398, the diameter is Collinder's maximum, and the brightest star V magnitude is the SIMBAD value for y Carinae.
