ED vs Non ED Camera Lens
Hi Gary, I made some errors in my post, and have corrected them, got ahead of myself as I have been trying out a lot of different Camera Lenses, Yes I will try stopping down the non-ED Lens see how it goes, I am amaized at the good colour on M42 Etc. with the Non-ED lens, If stopping down a notch or two sharpens things up, It makes you wonder about the additional cost of ED Camera Lenses for Astrophotography.cheers....Jim
