Lumicon 1.25" filter holder. Can take up to 5 filters. Each of the five holes is threaded for standard 1.25" filters.
It's an excellent way to quickly switch between different filters to decide which one is best for your chosen object. Compare five different filters or leave one hole empty to compare the unfiltered view.
The nosepiece (i.e. the bottom end in the picture) is also threaded.
Note that the nosepiece is fixed, i.e. it doesn't screw off.
It's in very good condition with some minor cosmetic scratches. Mechanically it's perfect and has been very lightly used.
