AstroZap 177mm x 177mm 視覺用Baader太陽濾鏡膜（視覺觀測用）- AZ1029

I’d been putting off making my own solar filter, but this film cuts cleanly and fits my telescope perfectly. The safety factor is reassuring, and the views of the sun were crisp and detailed.

The film is surprisingly easy to cut to size without fraying, making it simple to custom-fit my telescope. I can finally observe sunspots with crisp, comfortable detail during the day.

Cut a square to fit my existing filter frame and the film went on smooth with zero wrinkles, which surprised me given how thin it is. Was able to clearly see sunspots on my first try through my 6-inch dob, and the image stayed sharp even at higher magnification. Definitely feels like a solid upgrade
