Andrew Garrard Posted April 4, 2018 Share Posted April 4, 2018 For what it's worth, I do have a 200 f/4 (and a 70-200 f/2.8, and a 200 f/2). The 200 f/4 was bought specifically because it's very light for putting on an astro-tracker, and its filter size happens to be the largest strong light pollution reduction filter I could buy. (I also have a 77mm less strong filter that I can use on a 300mm f/4.) Sadly I can't get much closer to my subject... Link to comment Share on other sites More sharing options...
