Re: APCC model like Mach2

Am I correct that this feature is the same functionality Roland used via the keypad on the Mach2 to build a model
only along the path of the target to be imaged? If so that sounds like a big win for mobile imagers like myself.
The implementations are independent of each other, but the concept is similar. APCC's Declination Arc Tracking is an idea I first had over 15 years ago. The feature does not use the typical model that you would find in TPoint or other premium mounts. It uses hybrid modeling: pointing correction is handled with a full-sky model, but tracking rate correction is dealt with via a different mathematical model that is optimized for localized tracking accuracy. The tracking rate modeling accounts for mechanical terms that the full-sky pointing model does not and thus produces higher tracking rate accuracy than a full-sky model.
