Object(s): M83 (NGC 5236)
Category: External galaxy.
Class: SABc
Constellation: Hya
Data: mag 7.5 size 13.1 x 12.2
Position: RA 13:37 DEC -29:52
Description:
In Hydra, at ~ 7¼° S-W of Pi Hya. A long ovservation enables me to carry out a better study of this spiral. M83 shines at the 9x63; dimensions are really impressive. By analyzing the form, I note that the object is not perfectly round, I perceive some irregularities in his contour. No bright center, just a tiny increase of the brightness toward the core.
