You may find, as I did, that many compact cameras with manual control functions are not fully manual. Most of the lower end models will only allow you to use longer shutter speeds with lower iso values. This reduces the light gathering capabilities of the sensor thus making them unsuitable for wide field astrophotography. The manufacturer's logic in doing this is to reduce the effects of noise and make the images look better.
