Globular cluster NGC 1261

This is a short (12 sec) exposure of the globular cluster NGC1261 through an H-filter centred at 1.65 micron. Note the excellent resolution, achievable at this wavelength with the SOFI/NTT combination. The field measures 2.5 x 2.5 arcmin, with North at the top and East to the left. The scale is 0.14 arcsec/pixel. The stellar images are very sharp (FWHM around 0.7 arcsec).
