Integral field unit spectrographs allow the 2D exploration of the kinematicsand stellar populations of galaxies, although they are generally restricted tosmall fields-of-view. Using the large field-of-view of the DEIMOS multislitspectrograph on Keck and our Stellar Kinematics using Multiple Slits (SKiMS)technique, we are able to extract sky-subtracted stellar light spectra to largegalactocentric radii. Here we present a new DEIMOS mask design named SuperSKiMSthat explores large spatial scales without sacrificing high spatial sampling.We simulate a set of observations with such a mask design on the nearby galaxyNGC 1023, showing that the kinematic and metallicity measurements can reachradii where the galaxy surface brightness is several orders of magnitudefainter than the sky. Such a technique is also able to reproduce the kinematicand metallicity 2D distributions obtained from literature integral fieldspectroscopy in the innermost galaxy regions. In particular, we use thesimulated NGC 1023 kinematics to model its total mass distribution to largeradii, obtaining comparable results with those from published integral fieldunit observation. Finally, from new spectra of NGC 1023 we obtain stellar 2Dkinematics and metallicity distributions that show good agreement with integralfield spectroscopy results in the overlapping regions. In particular, we do notfind a significant offset between our SKiMS and the ATLAS$^\rm{3D}$ stellarvelocity dispersion at the same spatial locations.
