The FOV rotation angle allows to properly rotate a photo camera, with regards to the telescope mount, in order to image a galaxy (for example) with the most appropriate angle. Also, with a dual CCD chip (i.e. main chip for imaging + second chip dedicated to autoguiding), the FOV rotation angle allows to find the best guiding star (usually the brightest star around) previously identified. As opposed to other comparable simulation apps, including Starry Night 6 Pro, it seems that the FOV rotation angles in SN 8 Pro are defined with regards to the LOCAL axes rather than to the EQUATORIAL axes... thus being totally unusable when it comes to find the appropriate rotation angle that must be used to rotate a photocamera in order to image a given deep sky object.
Is there a way to make SN8 Pro behave like comparable apps i.e. consider the FOV rotation angles with regards to the equatorial coordinates rather than to the local coordinates ?
Thank you for your help.
