Dither without PHD2

[Former user]

Be able to dither after a set amount of images are shot by a set amount in a random or spiral. I could have a 300x30s sequence going and have it set to dither 30 pixels on the cam every 20 shots.

NINA already supports dithering every x number of frames, it is a setting in the imaging plan.

The dither aggressiveness can be set in the settings window, under equipment tab.

Dither without PHD2 requires moving the mount by a small amount, this is not super trivial to implement.

My apologies if this is extraneous information - SGP accomplishes this (dither without PHD2) by sending guide pulses (so at whatever the guiding rate of the mount is set at) for a set amount of user-configurable time - so it knows nothing about how much the mount moves. As far as I can tell, it gets the total pulse length from what the user set, and then applies it to one of the PulseGuide directions - and sends the pulses to the mount - overall, it seems to me similar to the old PHD guiding logic with its three levels of strength.
