Satisfied
Filters are doing what I expect them to do. So far I haven’t used the CLS filter a lot, because I’m mostly using the dual band on emmision nebulae. But both of these have an important place in my observations, considering the city light pollution I’m exposed to.
With regards to the ease of use, I have nothing to complain about. It’s satisfying to click the filter in. That’s not as important as the actual results they provide, but it”s a nice bonus nevertheless.
