We have carried out deep imaging observation near the invariable plane using Subaru telescope with its prime focus camera ""Suprime-Cam"". We have integrated single field of 0.2 sq. deg. deeply on 5 6 October 2002 and followed up detected objects on 3 December 2002. SDSS r'-band filter was used for this observation to maximize the number of detection. The limiting magnitude is r' = 28.0 for signal-to-noise ratio of 5. Assuming typical color of TNO it roughly corresponds to R = 27.7 mag. The aim of this observation is (1) to investigate existence or non-existence of distant TNO beyond 50 AU from the Sun and (2) to explore the faint-end of the luminosity function. All the detected TNOs have heliocentric distances ranging 38 < RH < 45 AU. We will report preliminary results of our deep survey.
