The main goals of this experiment were two:
1) verify if RGB imaging under a light polluted sky (Average SQM 18.5) is possible or not.
2) test the new procedure of gradient removal by Vicent Peris described here
Well
1) it is clearly possible if the target is bright; harder a fainter one.
2) it is a great technique much more superior than other gradient removal routines.
