NEEWER 58mmレンズフィルターキット

Disclaimer: The description of this product seems to have changed since I bought it. When I bought it, it was a set of 1.25" filters that fit telescope eyepieces and included a variety of 5 colored filters as well as a Neutral Density filter, an ultra-high contrast filter, a moon & skyglow filter, and a polarizing filter. That is what I received. Today the same product page now lists a set of more generic 58mm filters for GoPro that are bigger and only include 4 Neutral Density filters, a polarizing filter, and a UV filter. Not sure why the change, but it's clearly a different set. I uploaded a photo of the astronomy filter set I received and am reviewing.Quality wise, the filters I received seem reasonably good for visual astronomy. The different colored filters are useful to increase contrast of certain features like ice caps etc, primarily features on planets. The polarizing filter pair get screwed together before being screwed into the eyepiece and then can be rotated to adjust the filter level. It works pretty smoothly.They all thread reasonably nicely into my 1.25" eyepieces and the case holds them fairly snugly in place in the case. Each is clearly labeled for easy identification. This will be a good addition to my astronomy outreach gear particularly since these particular types of filters are not as difficult to manufacture and don't require the level of precision of the more complicated filters like narrowband and astrophotography ready filters.
