Hi All,
Further to Ken's modified Flip-Mirror beamsplitter I have 'hardwired' in an adjustable slit.

The slit was purchased from The Surplus Shed for US$15.
Top left - Modification (threaded unit) to allow the slit to thread directly into the Orion Flip-Mirror unit.
Bottom left -Attached unit.
Top right - unit with splitter up.
Bottom right -Unit with splitter in place.
