The MN190 is a great scope. While i use mine for imaging, i have not tried EAA. I can say that the ASI1600 works fine in high frame rate video capture mode (using Sharpcap) when building video files for planetary frame stacking. I can see no reason the MN190 could not do EAA given its planetary video performance. Of course, adding a 2x barlow for planetary takes you to effective f10, and its fine there.
