I bought the Star Focus Filter due to other reviews being favorable. I've used it once and I believe it helps. Move-Shoot-Move could use more instruction videos or information on this filter. Do you remove the filter after focusing? I guess so.
This may be a great product, but MSM needs to include further instructions for use. My filter came with zero instructions.
I would have wished, that the starfilter is at least 95mm in diameter for my NIKON 200…500mm lens. Other than that, it has fine grid and is nicely made
Easy Focus - Star Focus Filter - Precise focus on the stars is Easy with it
I have only been able to use a few time so far because of cloudy weather. Performs great as advertised, and the feature of all the different adapters was the selling point that really convinced me to buy because several of my lenses have different size filter requirements. Great product, thank you.
Great help getting star’s focused
Easy to use and stars are focused from test shoots to final capture.
Overall it’s a good quality tool. Because of the small apertures you are working with, use a very bright star so you can see the spikes. Also, get some step up/down rings so you can thread it to your lens, otherwise you are holding it in one hand, focusing with the other.
