With the C9.25 at F6.3 and the SBIG ST7 (30 min sub frames) I think that I once got down to around mag 21.8 from our back garden in suburban Brisbane when looking for Sycorax, one of the moons of Uranus.

Thanks Dennis, is great fun to push the equipment to the limit isnt' it.
Mag 21.8 thats impressive! Makes sense also given that my webcam has only around 1/3 the QE of the ST7 (from memory) and you also take longer subs. I must get an SBIG... hopefully next year.
