ASI 533MC-Pro - should my stacked lights look like this?

ngwillym

First light for my ASI 533MC pro. But I don't think my stacked lights should look like this - with a much lighter X across the frame.

Lights taken using ASI533 +ZWO UV/IR cut filter, 127mm Apo. Sub (8 seconds each) captured with Sharpcap using 'Live Stacking'

This X appears both in the saved integrated stack from Sharpcap and also when the subs are stacked using Astro Pixel Processor - all that has been applied is a standard 'stretch'. File reduced to 2000 pixels per side by Photoshop - just so the files aren't so big

Do I need Darks, Flats and/or Bias for this camera?

Thanks in advance

Neil
