I’m using SkyFi 3 with SSF 5 Pro with my iPhone 6 with my new Atlas Pro Alt Az. The mounts go to’s are very accurate using the HC, but as soon as I connect the SkiFi and use the SSF, the go to’s become very inaccurate meaning objects are barely in the field of view or completely out of it.
For example 2 nights ago I was observing in Alt Az mode using the hand controller. I slewed to about 15 different object in about an hour. Extremely accurate. Upon hooking up the SF and SSF, the object which was perfectly centered in the EP was off center on the target cross hair target on the SSF 5 Pro screen. I slewed to a number of objects and even after using ‘align to object xxx’ the objects were all poorly centered or out of the EP. Then I disconnected it and went back to the mount's HC. The accuracy became excellent again by just using the HC go to’s.
I use SSF 5 Pro with my Evolution mount and there's none of this problem of inaccurate go to's, so I'm thinking its a problem with this mount and SSF.
