I've set up custom equipment settings for my telescope, CCD camera, and guider, but the custom FOV overlay does not appear to be affected the "Scope Display Coordinates" setting (Under settings->Telescope->Display->Scope Display Settings); it remains locked to whatever scope type is set under settings->Telescope->Setup->Equipment Selection->Mount Type. I'm running SkySafari Pro, ver 126.96.36.199 on an Android Samsung S6. I'm not sure if this is intended functionality or not, but it did confuse me greatly at first since the "Scope Display Coordinates" seemed like it was the setting I should change to alter the FOV display. I've never connected SkySafari to my LX200, so I had not thought to look into telescope control setup for settings that could affect the FOV display. I'm guessing the "Scope Display Cooridnates" setting is redundant and unused in versions of SkySafari that include telescope control? If so, it would be helpful to have an asterisk or line in the manual under "Scope Display Coordinates" directing users to the right setting for SkySafari Plus and Pro.
