Early Unitron Press-On Solar Filter

Description

1950's era Unitron solar filter. These are designed to press fit onto the top of any Unitron 0.965" series eyepiece. The glass condition is clean and clear. The cosmetic
condition also good for a vintage item like this.
Note that direct viewing solar filters of this type are no longer considered safe by experts for use due as they sometimes crack under solar heat, so this is being sold purely as a collectible for display and collecting purposes. Please do not attempt to use it.
