HELP - Black (no data) in FITS Images taken by sequence (others OK)

Odd problem - Camera QHY183M - set correctly and “Take One” and Plate Solve images appears fine BUT images taken via the sequence all have now data! - The FITS header is populated and the files size is correct but the data inside is all black even when stretched - image taken by Focus/Framing for the same duration are fine as are those taken during the plate solve process - This has me completely bamboozled - any help greatly appreciated

Note: using ASCOM driver which appears to set correctly - using same camera with NATIVE driver in other SW is no issue - so somewhere between ASCOM and the download the image appears to be turned a uniform black/nothing

Maybe check that you’re not overriding the gains in your events and setting them to 0? Can you post your SGP log.
