Both need low aberration optics and binoculars also need good alignment to acomplish it...3rd, non HD spotting scopes like the Swarovki show a lot of CA and most astronomers are not used to how all medium and high end spotters perform. On the pm you sent an ATX95 was used to make 1/2 of a comparison <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> , but the owner never mentioned resolution and said the APM showed 3 times more CA.4th, CA is a problem in BT´s and we all have understand that. No way a semi-Apo doublet will perform like todays best high end spotting scope, the ATX 95 regarding transmission or color correction. But that is the answer I am after....if the APM semi-Apo has as good resolution at 50x or 60x and suffers from the same amount of CA than an non HD medium or High end spotter, their are still a good value. Their QC and collimation issues is what concerns me more...I will be back to this as soon as I have more substancial news and facts, I dont whant to monopolize the all thread with high magnification binoculars (BT), we must let others give their opinion <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /></blockquote>
