[QUOTE="Rui_Caratão, post: 2971925, member: 80272"] Before we make judgements we must have sure what those images represent. They could be cropped versions from the original image, certainly from outer portion of the field of view where CA is more noticeble....on that Vixen BT link you posted, there is a second cropped image showing exactly this at 27x [url]http://www.davidesigillo.eu/images/tele/bordi.jpg[/url]. Second, the target chosen maybe on the origin of diferent levels of CA, since high contrast on black and white subjects induce more CA like in both APM images, the Vixen image on those roof tiles is not so good the induce CA. Like I said before I still have high hopes for Vixen BT81 or APM semi and full Apo, but perhaps is better to ask directly to owners how those instruments star test, or how they perform in daylight with quantifiable resolution data, otherwise opinions may differ substancially. Another quote from CN on an older APM semi-Apo thread. [url]http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/3986454/page/0/view/collapsed/sb/5/o/all/fpart/all/vc/1[/url] [B][I] "Almost forgot to mention..... Since I was at Yellowstone, I also used the binocs for daytime wildlife viewing and found NO, ZERO, NADA, color fringing at 23X. Images were razor-sharp and wonderfully 'contrasty'. Set up next to a top-of-the-line KOWA spotting scope (I think it was 82mm), the views with the APM 100's were noticeably more detailed (and being able to use both eyes was, of course, vastly superior). This was also a pleasant surprise. "[/I][/B] [/QUOTE]
