The 8SE tracks, but only in alt-az, not equatorial. So although it will stay centred on your target, everything around it will rotate like a clock (called 'field rotation') because it is tracking along two axes (altitude and azimuth) instead of one (RA). So you can only take short (20-30 sec) exposures before this becomes bothersome.
This is absolutely fine for visual - just an issue for longer-exposure AP.
The Dobsonion also moves in alt-az only.
