Description

This was First and Second Light for the Starizona "Night Owl", 0.4X SCT Reducer_corrector, using 38.1mm spacing on a C5.

"Original" un-cropped, first light

"B" : Same as original, cropped

"C": Second Light, where I performed a better collimation and also loosened the clamp collar, which may have been pinching the optics (?). No flat frames or dark frames, so the vignetting is evident but could have been easily corrected.

"D" Same as "C" cropped

E: Same as C, with dark, flats and dark-flats applied

F: Same as E, cropped
