The binocular that has the thinnest and least purple fringe around the object has the best CA control. All binoculars will have some at the edge and less at the center. It is easy to see the FL is better than the HT and it doesn't take hours of observations under different conditions or you don't need to take the binocular apart and take pictures of the inside of it either. You can take ten binoculars and rank them in a matter of minutes. Easy peasy! Don't make it harder than it is. If you don't like CA the FL is your binocular. I do the CA test on almost every binocular I buy and when I tested the FL I went WOW that baby is really good for CA.<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /></p></blockquote><p></p>
