New Reducer [#7872] for 90FL and 71FL

Now it’s the time to officially announce the newly-designed dedicated super reducer [#7872] for 90FL and 71FL. It will be commercially available this spring.

DSC09874ss2nd prototype

 

Features are

1) 0.72x quadruplet design for full frame sensor

2) 90FL = 360mm/F4 and 71FL = 288mm/F4

3) 48mm filter in front

4) Fits filter box(# 7519) and camera rotator (#7352)

Since the lens section is moved into the inside focuser, the distance between the focuser and camera gets much closer (less stress for the focuser). As a result, it allows to use relatively longer main tube (easier setup).
Well mechanical design!!
