Here is a picture of my FS152 with new 3" FeatherTouch focuser. Its a huge improvement over stock focuser even with the the FT micro unit.
My scope is a later "NSV" model which has a shorter OTA but uses an extension tube so the scope will focus visually. In the stock configuration TAK threads a ~4" extension tube onto the back of the focuser drawtube. I wanted to do away with extension tubes so the tube adapter - the piece of plumbing needed between the focuser and OTA - was made longer.
This sample of the FS152 performs quite well. A friend and I were comparing it his AP155 on Jupiter and some double stars Saturday evening. Other then the slight difference in color correction, you really could not see much worth arguing about when comparing the views. These Fluorite doublets really do not give up much visually to modern oiled triplets.
