Iris reduction – A must have
Help to get F30 ratio at lower focal Change the bandwidh of the Daystar filter in a second ! If full aperture at F20 the Daystar 0.5A is acting as a 0.8A! The result : proms a even greater !

Taka x1.6 extender
The issue : No ring ! With the weight of the bino head, it rotates and damages the diagonal nose!
The solution: Drill a few the nose of the diagonal so one screw can fit inside. It rocks! : no more move at all.
