These are the typical CCD Inspector results with the SBIG ST2000XM camera used on the TMB130 SS OTA. These examples were taken
from an imaging session of NGC 6946 in Cygnus through the luminance filter so there are plenty of stars used for these measurements.
The results show a very flat field and no flattener is needed.
The sensor size is 8.9mm X 11.8mm with a effective FOV of 33.5 X 44.7
arc minutes using 7.4 X7.4 micron pixels.
