Apologies, I missed this question. I use the Baader ASBF 50. Given your comments above about needing to quickly remove the filters during the totality, I wanted to avoid threaded filters. Looking at the binos, I assumed the Baader filters would not have anything to grab onto, so I took advantage of the threading and ordered a pair of these 52mm threaded hoods. The setup with the ASBF 50s and the hoods works great, and the hoods are short enough they don't vignette at all.
