Very nice!!
The? Rayleigh limit for a 105mm aperture is 1.31 arcsec so you won't really see the difference in RMS guiding unless it is spikes being eliminated.? Even unguided, if you're running a smooth +/-2 by the time you factor in atmospherics, your pretty much there, as your photo shows.?
Nice to hear success stories posted!
Of course there is a solution to this Non-Problem
...in this case buy a bigger telescope ?

Clear skies!
