Celestron EclipSmart Solar Filter For 70mm Refractor (94221)

I bought the Celestron Travel Scope 70 for the Aug. 2026 eclipse. I'm happy with some test results on the Moon, but needed a solar filter for the partial phase before totality. It's a 40 mm diameter filter, so sub-diameter to the 70 mm objective lens. I took some test shots of the Sun with the filter, and it does a good job, capturing sunspots. For the price, it's a good addition to my eclipse gear.
