I've been trying to compare optics and reflectors lately to see which provides the tightest hotspot in each group. What's the difference between a fraen and fraen LP optic? How much better is a 30mm compared to them and what is a tiros optic? As far as reflectors I know of there's a 17mm , 20mm and a 27mm but since I don't have any of them I don't know which is best for my needs.
