Astrodon Photometrics Sloan FiltersI just (July 31, 2018) finished updating the inventory numbers on the website and the stock is looking MUCH better than it ever has ever looked since OSI acquired Astrodon. Most (but not all) Astrodon filters are in stock, including the narrowband filters that everyone has been waiting for! So I think that we have really dug ourselves out of the deep hole that we were in and future wait times will be much more reasonable.
