(no date)

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (218x, 346x)

Soft round to oval glow with an outer envelope. I think it is brighter than the suggested magnitude. Sports a strong brighter nucleus. On the immediate west of the galaxy a 13magnitude star can be seen. Four more stars outstanding toward the west, drapes in a N to S direction. Galaxy display a very soft outline and brightens up to a very bright nucleus which made it quite outstanding against the background stars. Four stars arrange in a half moon to the close west.
