NEW Reducer/Field Flattener V. III, especially recommended for users of the William Optics Z70, M72, M80, and M90 telescopes. The large 50mm clear aperture lens will reduce vignetting to almost nil. Simply loosen the set screws on the side and your adapter will rotate 360 deg. with a thumbscrew to lock it into place!
The antireflection multi-coatings on all optical surfaces will boost transmission and enhance your astro-imaging performance!
What you care most, your shots will show pinpoint stars and you will maximize to the fullest your apochromatic refractors' potential.

It's pretty much the only choice.Pros:
Strong Construction,CompactCons: Comments:
This is pretty much the only choice for reticle eyepieces and for finder scopes. And it is only available here. I did purchase another brand a while back that had a flashing feature but it was big, bulky, and broke after first use.
It would be nice for these things to turn off automatically after a few hours of non use. I just can't seem to remember to turn them off and I'm always replacing batteries.
