Inspired by Jeff's recording of Sycorax (a moon of Uranus), I managed to record down to Mag 21.86 with a Celestron C9.25 at F6.3 with an SBIG ST7E CCD camera using 30 minute sub frames, shot from suburban Brisbane (7kms from CBD).

Using my Vixen 4” f9 refractor and SBIG ST7E CCD camera, with 15 minute sub frames, I have recorded stars down to mag 19.18.
