Support@Seestar You are making the wrong assumption here that planning is being done at night, with the S50 on and connected to the app. I do the planning during the day, even if I turn the S50 on and connect to it, there is no way to put it in EQ mode. You should assume that the time and date when doing the planning are not related to the time and date when the plan is executed.
When I do planning in EQ mode I expect the red rectangle telescope viewport to be aligned with the EQ grid on screen, after all that will be the orientation of the scope when doing the capture and that is independent of time and date in EQ mode. The red rectangle should be vertical in Alt/Az mode and the grid should reflect the time and date of capture not the current one, when making the plan. In EQ mode the rectangle should be rotated to match the orientation of the EQ grid.
This is one major advantage of using EQ mode (apart from no filed rotation) - you can make plans that will work no matter the date and time you use them. It is much easier to create your own mosaics and you can use the same plan on multiple nights if you want. Add an "execute plan now" button instead of being tied to a fixed time and I will be very happy.
