Please help.
Since it was updated to version 2.3 I have had guidance problems. The main telescope is now a Radian 61 with 275 mm focal length and I am guiding with a Gelestron C8 at 1426 mm focal length. The RMS is perfect, 0.3
at 0.7 but for this telescope, with my ASI 2600 MM RMS values lower than 2", the stars appear as point stars. Now with lower RMS values the stars appear double, as if it is collecting light for a few minutes, it moves and guides, making the star double. I have disconnected the Dithering, but it remains the same.

Any advice?
