We present the blind Westerbork Coma Survey probing HI content of galaxy cluster with Synthesis Radio Telescope. The survey covers inner $\sim$ 1 Mpc around centre, extending out to 1.5 towards south-western NGC 4839 group. probes atomic gas in entire volume down a sensitivity 10$^{19}$ cm$^{-2}$ and 10$^8$ M$_{\odot}$. Combining automated source finding extraction at optical redshifts visual v...
