Description 
Add an optional manual dither control to the Color Series form. Marco Lorenzi says the auto amount is too small. Or should I just increase the auto amount?

  Completing the change to always use main imager pixels for dithering values.

  Added Preferences Dialog, Imaging tab. Guider Plate Scale field, and Prefs.Autoguiding.SensorPlateScale property. Rebuild interop assembly for Scheduler.

Bite the bullet! Provide a place to config the guider's plate scale, then do all dithering in main imager pixels. This is the right way!!

Add to this Jack Harvey and SSRO's experiences in this Comm Center thread. This needs doing, I have accepted it.






It may be that few people are explicitly dithering, and switching to main imager pixels for guided dithering will have a minimal impact. That would be the right thing to do. GIven the variety of guiding setups (guidescope, OAG, internal) having the observatory operator put in the guider plate scale seems like the best option.

Allow specifying in arcseconds (Patrick Lau in the IdeaScale discussion)? This is not what you want in my opinion, since you don't knwo the plate scale. You want to dither in main imager pixels. Really, one should provide a conversion between guider and main imager pixels and allow the user to dither by main imager pixels. The problem is that ACP plan language now uses guider pixels for guided images. More thought needed.
