These filters fit the XL100’s perfectly! No slop or tightness. Gives a wonderful orange tint to the image, unlike the mylar types that have a whitish blue cast. They look great with that brushed steel finish.

I bought these as a supplement to my BT100XL SD binoculars. It’s a little disconcerting the first time one points binoculars toward the sun (a lifetime of warnings is hard to shake), but when the sun came into view it was an incredible experience. I could easily count 8 sunspots as the image remained crystal clear. These enhance the usefulness of the binoculars and now I’ve got my solar filters for the eclipse in 2024.
