I use a QHY10 and understand that the ASCOM driver downloads and presents images ‘diagonally flipped’ from the normal landscape view. ‘Diagonally flipped’ means the image is horizontally flipped and rotated by 90 degrees. Rotating the image is only half the job. Nebulosity 3/4 does the full rotate and flip. I think the SGP change is a very good initiative - it is much better to view images in landscape - but I also recommend that images should be both rotated (I think clockwise) AND then horizontally flipped - i.e. all or nothing.
