Flips"},"content":{"rendered":"\n<p><a>Flip Angle<\/a> \u2013 The \u201cFlip Angle\u201d setting is the amount of degrees, before and after the meridian where everything in-between is known as a flip zone. \u00a0When the limit is reached certain actions can be taken on the main menu under Axis Limits such as Do Nothing, Stop Tracking, Park, or how log to track after reaching the flip angle.\u00a0 Each degree equates to about 4 minutes of sidereal tracking time.\u00a0 The default setting is 20 degrees, so this means the flip zone is 40 degrees total, 20 before the meridian and 20 degrees after the meridian. \u00a0<\/p>\n\n\n\n<p><a>Imaging Applications<\/a> \u2013 Applications like NINA or SGP can take advantage of flip zone by forcing the flip using the \u201cSide of Pier\u201d command before or after hitting the meridian.\u00a0 It\u2019s recommended that the flips occur well before hitting the Flip Angle setting.\u00a0 This way the limits can be used as a safety factor and an action can be taken if the flip failed from the image acquisition application.\u00a0 Applications like Voyager use the \u201cDestination Side of Pier\u201d to determine when a flip can occur.\u00a0 Basically it ask GSS if a goto was executed what side of pier the mount would end up on.\u00a0 Based on this Voyager would test the targets coordinates to see if a flip can occur.\u00a0 To properly accommodate applications that use a goto, set the Flip Angle to either a setting of 0 or 1 and the Axis Limits to \u201cDo Nothing\u201d.\u00a0 Then tell the application to wait a number of minutes, typically 1-5 minutes after passing the meridian to test for the flip.\u00a0 If the flip fails then the \u201cTracking Limit\u201d will be hit and the action selected will be taken.<\/p>\n\n\n\n<p><a>GoTo and Slews<\/a> \u2013 The \u201cFlip Angle\u201d also affects gotos and slews.\u00a0 Any target within the flip zone can be pointed at by either side of the pier, that\u2019s the purpose of the zone.\u00a0 To determine which side of pier takes action depends on what side is closest.\u00a0 i.e.\u00a0 Say you\u2019re pointing east and about 45 degrees in altitude and you want a target that is 5 minutes passed meridian.\u00a0 Since the target is in the flip zone and the mount is in the pier west configuration the slew will not flip the mount because the axis is closer on the current side.\u00a0 If the target was passed the flip zone then an automatic flip would occur since that\u2019s the only pointing state that will work.<\/p>\n\n\n\n<p><a>Additional
