For my flats i have been using a EL panel behind frosted perspex all seemed fine until lately and after processing seemed to have lines running across screen a bit of playing around i found the issue was the flats and more so the EL panel ,now i dont know if the EL panel has a fault or the power supply causing the issue maybe some sort of refresh rate issue ,has anyone had issues with using EL panels , i use a Nikon D5300 and image in APT ,now using AV mode using the 5300 is not as simple as a canon when no lens attached so measure exposure in AV mode in APT then manually set a flat plan a bit long winded but simple once you know the exposure for your light source ,i would like to measure the ADU of my flats can anyone tell me how if can be done using Siril ?attatched files show I/40 sec using an EL panel showing red as i have used a sheet of pink paper and two sheets of tracing between El panel and perspex , 1/500 sec from a tablet screen and a previous shot of m52 showing the lines i proceess in siril and Dither so i only use lights bias and flats when imaging ,So could someone take a look at my flats and tell me if they are any good is the EL panel flat any good compared to the tablet Flat .
