Learning to slew this new-to-me telescope to the object, and thankfully Ophiuchus remained high in the sky for this session. I have viewed M10 numerous times with 10x42 IS binoculars so knew generally where to look along the line (1/3 of the way up) from Sabik to κ Oph.
It was a very faint roundish object. I could not see any individual or bright grouping of stars within the cluster.

I wanted to view this cluster in Ophiuchus with larger magnification and did so this evening. I could actually make out some of the stars in its nebulosity with eh 25mm eyepiece (100x magnification). It had a bright core but was seemingly diffuse. There was one bright star north of it then several on the opposite side of the object.
