BORG Objective Filter Cap

These parts are the limited production. Front caps allow for quick attachment/detachment for high-quality solar filters.

[5682] for any 100/101 and 82mm filters

[5672] for any 76/77 and 72mm filters

76/77 have 82mm/77mm filter threads in front of the objective lens cell. But this is useful for the quick switch. 100/101 has no filter thread. So cap is needed for 100/101 anyway. 45/50/60/71 have all filter threads in front of the hood.
