NGC 3918 'pulsating'
Finally got a chance to roll the roof back on observatory last night,had a look at 3918,its such along time since I viewed it,I seemed to get brighter,then fade,then do the same again as I viewed-it may have been my averted vision,giving this effect-but it did seem bit different to last time I viewed it,but that was some time ago-so may have been the same.
