M83 – Galaxy in Hydra – Difficult Due Only to its Southerly Location

M83, NGC 5236:  Galaxy in Hyra

Date: April 9th 1997

Telescope: 10-inch f/4.5 Newtonian reflector Magnification: 57x – FOV: 0.50º – 1/2º Conditions:

Transparency poor due to southerly latitude:  NELM 4.5 at zenith

Visual description: Very bright, stellar nucleus, brighter elongated central region, oriented NNE-SSW, with a faint mostly round halo. With patience and averted vision, a very subtle curving arm, ESE of the core. This was very surprising considering the sky glow and southerly location of this galaxy from my backyard. Despite the light pollution, and haze, this galaxy was fairly easy to locate using the 10-inch at 57x.

My first recorded notes of M83 are…as following, but not my first observation. My only regrets as an amateur: I just wish that I had started making observational notes and sketches when I did my first deep-sky studies at a very young age in the fall of 1966.

May 1992: 10-inch reflector @ 57x: Faint, mostly round, but a subtle elongated shape when using averted vision. Very difficult due to unshielded street lights in very close proximity of my backyard.
