Micromega Critial Focuser Pro.Z.Koana System Grain Focuser -Chipped- [BAR]

This is a high end grain focuser. This one's mirror is chipped in the upper corner (see photos), I do not know how much this will affect its use. Otherwise it is in good condition with moderate wear and works perfectly. The glass has no haze or fungus. SKU: 250613-18
