Dithering with Sky Adventurer Mini

I think Fred's formula is exactly the same as yours, just simplified.
(206.3 * 10) * pixel size / focal len = arcsec
(206.3 * 10 / 60) * pixel size / focal len = arcmin
34.383 * pixel size / focal len = arcmin
So I guess 35 give you approximately 10 pixel dither, and if you want 15 pixel just multiply by 1.5.
Nice post guys!
