M30 is just 20 arcmins E of a 5th mag. star. The first quarter Moon is c.10 degrees E. There is a haze in the air, NELM is only 4½ near the N pole and worse around the horizon. This all combines to give a mediocre view of yet another globular emaciated by its southerly declination. M30 is a pronounced oval shape, ratio 2:1 with the long axis EW. The long axis is only 1 arcmin long, so I am only seeing the core. The outer parts are grainy, so partly resolved. There is a short straight chain of three stars running N from the centre and a second similar chain running NW. In the fuzzy viewing conditions it looks rather like a mushroom with the N chain being the stalk. This is usually the last object in a Messier Marathon.
