Description:
I found ngc 253 using the Planetarium for Palm software,then I follow the Beta
Cetus star, and two triangle asterisms next the galaxy.I confirm the position
using a 7x50 binocular, where the galaxy was seen only by averted vision.
Therefore, using a newtonian 100mm reflector the shape and details of the galaxy
disk could be easily visible, including some dark areas of the disk.
