I really suggest you put a quality star diagonal in it or go straight through, if it will come to focus straight through and star test it after it has had at least an hour to settle down. And look at a star at least 60 degrees above the horizon. Bad seeing can make a good scope show a bad star test. Both my ED 103s an the A105M star tested better than my Stellarvue SV102T triplet or my Tele Vue 85 doublet.

Thank you, I feel encouraged not to give up on Vixen. As for this particular OTA, I returned it to the vendor after a straight-through star test failed (see my post above). In the meantime I bought a used A80M, can't wait to get it.
