neil phillips Posted March 20, 2011 Share Posted March 20, 2011 Im trying to determine if moving my primary foward has caused any vignetting. Its not something ive really dealt with before, so my question is how obviouse would it be ? i looked at a full moon with a 12mm eyepiece, and i saw no signs of it, but would the power of the eyepiece influence this ? Cheers for any feedback Link to comment Share on other sites More sharing options...

neil phillips Posted March 20, 2011 Author Share Posted March 20, 2011 Not sure that works with vista John, but cheers anyway. If there was vignetting i think it would show, i also saw none on my screen via the ccd ? Link to comment Share on other sites More sharing options...
