Elle permet d’envoyer à la monture des impulsions de dithering sans avoir à installer de dispositif de suivit, pas de PHD2 et pas de caméra de suivit. Ça fait des câbles en moins.

Je l’utilise avec une monture HEQ5 dongle Wifi et Synscan ASCOM mais j’ai pas l’impression en regardant les brutes qu’il y ait du dithering.Using Dither Only Guiding
Dither only guiding provides a way to include dithering in your live stacking and imaging sequences without needing to actually have a guiding application/device active. Dither only guiding is considered by SharpCap to always be active (guiding), but will never send guiding corrections to your mount. Dither only guiding will however send a small, random, movement command to the mount whenever dithering is needed.
When using an ASCOM mount, Dither Only Guiding will use the Pulse Guiding functionality of ASCOM to send movement requests to the mount. This is available on most (but not all) ASCOM mounts. You may also be able to adjust the rate at which the mount moves in response to the pulse guiding requests in your ASCOM mount setup.

SynScan app does respond to ASCOM's PulseGuide command in both RA and Dec direction. It's just that SynScan app applies some filtering: when app receives PulseGuide command on an axis AND that axis is already moving, app ensures that PulseGuide will not reverse the original direction. App will only speed up, slow down, or stop the axis.
