So I bought the 100x100mm filter to use on multiple lenses with a filter holder. It worked so well. I was using it to find the E3 Comet and focused on the stars around it and it worked out great! Easy to use but make sure you digital zoom for focus magnifier so you can see it better. Really good buy for my gear.
Star Focus Filter - Available for Pre Order
This filter works really well. Bright stars show up in live view nicely. Dimmer stars you will need to take a test shot and view the photo. Great addition to my setup.
Works great on my 200mm telephoto lens. Quality on these are nice too. The adopters fit my lenses perfectly.
The product arrived quickly
Works like a charm. Thanks.
I tried this at 14mm - 24mm and did not see the pattern, but have heard other brands generally have this problems also.
at 70mm and above worked great, did not have lens handy to determine where it started working between 24 and 70mm
Very precise and useful accessory for astrophotography!
Havent had time to use it. Can't review.
