M9 was found as the lowest point of a triangle with Sabik in Ophiuchus and Xi Serpens. It was small, very faint. Its core was bright but the narrow border was only slightly dimmer. Couldn't make out specific stars in teh core but the variability in 'texture' suggested many stars. There was a bright star just outside the nebulosity - HR 6435 perhaps (?).
I tried 30mm, 25mm and 15mm to get more detail but there was no improvement; it just became more indistinct.
