Unguided in this sense means he didn't have computerised guiding (using a guidescope+webcam+software) to correct tracking errors introduced by the LX200's tracking mechanism.
The LX200 would've still been tracking across the sky using his wedge.
Very nice shots Paul, apart from the bright core of M83 that's exactly how it looked in teh eyepiece the other night.
Is it possible to take any more exposures and stack them, or go for longer? Is your mount not exactly polar aligned? Will you be able to longer exposures eventually?
