Fantastic piece of kit for you telescope
At first I was a little worried looking through a telescope at the sun. But after installing the filter for the first time, those worries went away. It's basically a lens cover with a solar filter in the middle, fits snuggly and confidently, and there are safety Velcro strips as well. I highly recommend this filter to anyone who want to view the sun and see the magic.
Very good, if you really have to point out a defect, it does not clip as smoothly as the original cover.
