Victor,
Sounds pretty normal.
The coloured pixels are due to various issues - hot pixels which show a signal even when there's none, different sensitivities of the pixels etc etc
These can usually be suppressed by taking a series of DARK exposures (cover on) at the same exposure length (ie 10 sec etc) at the same temperature and then subtracting this DARK from the image.
HTH
