ASI533, exposure 30 seconds, Gain 350, cooler on at zero C, Target C/2022 E3, Linux OS, EKOS/INDI Each high gain image shows a moderately faint red grid from corner to corner, what did I do wrong and how do I eliminate it from 180 images ?
please send pic to me “Walf.Wu@zwoptical.com” to check,thank you
Walf@ZWO Thanks for responding. The grid was eliminated when Darks and Flats were added to the stacking software. The grid only appeared with gain = 350 exposure 30 seconds used for imaging the C/2022 E3 comet otherwise No grid on other imaging sessions. Thanks for responding. Bill in California
