20′ × 20′ field of the red DSS image of NGC 7129. The 150 arcmin² area surveyed with the WFGS and the region imaged with LRIS are outlined. The KPNO T2KA imaging data encompasses the entire field of view. Filled red circles mark the positions of Hα emission sources, green crosses represent X-ray detected sources from the Chandra ACIS observation, and open red squares show the positions of Class 0/I/II sources that were not detected in X-rays by Stelzer & Scholz (2009) or by the Hα emission survey presented in this work.
