  In this work we present combined optical and X-ray cluster detection methods
in an area near the North Galactic Pole area, previously covered by the SDSS
and 2dF optical surveys. The same area has been covered by shallow ($\sim 1.8$
deg$^{2}$) XMM-{\em Newton} observations. The optical cluster detection
procedure is based on merging two independent selection methods - a
smoothing+percolation technique, and a Matched Filter Algorithm. The X-ray
cluster detection is based on a wavelet-based algorithm, incorporated in the
SAS v.5.2 package. The final optical sample counts 9 candidate clusters with
richness of more than 20 galaxies, corresponding roughly to APM richness class.
Three, of our optically detected clusters are also detected in our X-ray
survey.
