Excellent solar filter!

I hadn't considered using a solar filter for my refractor, but decided to try this one out. It works perfectly! I was going to monitor the solar eclipse with my Coronado, but opted to use this filter on my Askar FRA600 to tune the system before totality. I detect absolutely 0% image degradation.
Sunspot on first use

This was easily assembled, with very explicit instructions that are included. It fit snuggly over my SkyWatcher Esprit 120mm. Shortly after, I was looking at a new sunspot, very safely. Works as advertised and can be stored safely and securely in the original box. Works great in companion with the Televue Sol-Searcher as a finder scope.
