موصل 1.7XR لتحويل FOA-60 إلى FOA-60Q (TKA28595)

I’ve been using this extender for a few weeks, and it’s remarkable how sharp the images stay even at 901 mm focal length—the glass really delivers. The solid metal build feels reassuring when threading it onto the scope.

The Strehl ratio holding up so well with this extender really impressed me on my first clear night out. Mounted easily onto the FOA-60 and gave that clean, sharp 901mm focal length I was hoping for.

Was pleasantly surprised by how well the 1.7XR held the Strehl ratio; the optical quality didn't degrade at all when I attached it to my FOA-60. Jupiter's bands came through noticeably sharper than I'd expected at 901mm focal length.
