BORG Iris

As far as I know, BORG is the sole company who allows to add iris function into telescopes. Basically optical system must be modular design since iris should be set just behind the objective lenses.

Well-made!! Since it is virtually round shape, it creates beautiful BOKEH.

Iris allows to control the depth of the focus and the illumination without variable ND filter. These are very good value for image enhancement and make imaging process more fun.
