    I wanted the best usa focuser on my explore scientific 165mm triplet. The ES focusers are a bit rough. I hope the combination of best glass and best focuser works out. I mounted the focuser on the original ES lower bracket as the FT 152/165 bracket would not allow the scope to achieve focus (so I used the original lower bracket and saved $300 as well). Texas star party starts in a couple of days. I will be doing visual and some imaging. Will report back after the event.
