Vignetting with nebula filterPosted By Jim Nelson |
When I use my Orion Ultrablock with any "max field of view" eyepiece (i.e., 27mm field stop in 1 1/4" format), I get a dark, fuzzy edge of field. Is this going to be inherent with any screw-on filter and a max-fov eyepiece, or are other filters designed to give you that last teensy bit of clear field?
