Hi Ric,
You can also use the Envisage software to reduce field rotation, draw the first box in the DSI preview screen around the primary target, then a second box around a star toward the outside of the view, it aligns them as it stacks them ( and tries to de-rotate ) and if you then also seperately link the laptop to the rs port on the lx you can self autoguide of sorts as the software will drive the LX to try and keep the image centered and de rotated ! .. it works, but it's not perfect. Once you get the wedge, you can do quite a lot with the envisage software ( as I'm slowly learning ! )
