   Fits perfectly on an Apertura AD8. It works exactly as advertised. The only real downside is that the filter is relatively heavy so you have to re-balance the AD8 when you use the filter (unless you want to spend a lot of time fiddling with tension for the scope). I wound up putting the AD8 almost the limit, but fortunately there are scales so it

   doesn’t take long to change to/from the filter back to “normal” balance settings.
