Dear All
Despite the crappy moon I had a look through my new toy tonight. I got in about 30 mins of viewing before the clouds won.

I set up the scope this afternoon and had a look at some distant trees. There is a tiny amount of blue fringe using an 8mm teleview plossl but nothing at all through the supplied 10mm eyepiece. (that looks like a Meade wide angle series 4000)
Tonight I aligned first on centaurus A through the clouds. The double is perfectly clean split with a 24.5mm eyepiece and also with the 10mm. I wasn't able to make out any diffraction rings as the clouds were getting thicker.
I then aimed at spica. It was in the clouds but also showed no false colour.
By now the entire sky to the west was clouded so I aimed a Jupiter in the east. Using the 10mm eyepiece it was lovely and clear with no false colour.
I wasn't able to assess whether the field is flat photographically because of the cloud but the stars seemed to have the same focus at the edge of my 24.5mm eyepiece to the centre.
I 'm looking forward to trying the scope out some more but will need the clouds to go.
