Dithering settings

[Chefgage]

Morning all. Is there any 'rule of thumb' when it comes to dithering settings based on the equipment you use. It's the next step I am going to use to improve my images. The equipment being used is a canon DSLR with pixel size 3.72um. The dithering will be done via an asiair pro connected to a heq5 pro mount. The scopes focal length is 420mm. The guide scope focal length is 128mm.

Any thoughts??

An often quoted Dither is 12 DSLR pixels.

If the selected Dither is Random i.e. each Dither is in a random direction, and a random amount up to 12, then maybe a larger setting, to give an average of about 12 ?
