We present a methodology, based onthe correctionfor the limb darkening and the use of a directionally sensitive operator the “MadMax”, for the image processing of observations obtained near the solar limb. Our image processing method substantially enhances near-limb observations and permits an insight into the studies of the very fine chromospheric structures, over higher-resolution images. Space/time images produced from filtergrams processed with our method indicate that polar surges and spicules are probably related to different physical mechanisms.
