Filters in stock ship usually ship within 3 weeks.

You may click the “Get an alert” button to be notified when an out of stock filter is back in stock. It is necessary to pay for back-ordered filters immediately to reserve your spot in our wait list. Often we have more orders for out of stock filters than we have incoming filters. Many Astrodon filters are perpetually out of stock for this reason.

UV-Blocked Clear filters with 395 nm cut-on (50% transmission at 395 nm) and at least 97% transmission to 1000 nm. Often purchased with our photometric filters.
