| 8" F/6, Optimum Secondary Size?
Forum List | Follow Ups | Post Message | Back to Thread Topics Posted by Marty Pinson on September 6, 2001 14:47:29 UTC |
Was originally planning a 10" but I came across a good deal on a 8" mirror with a 3mm chip on the edge. So what would be the choice on the secondary. I found a good deal on a 1.50 and a 1.83. My illumination would be excellent with the 1.83 or is it getting to big? |
