The practical detection limit for a 0.4m scope and CCD is around R magnitude 22. You will find that many 0.35m scopes + CCD's have been regularly able to detect moving targets at R Mag 21 in the UK, US and Australia. Of course this will vary with sky brightness (and I am not talking about darks sky limits here)
