This is my Pacman Nebula image from last night. It was taken with QHY10 with WO GT71 scope and STC duo narrow band. Total exposure time was 150 mins (600sec*15 subs). Lights frames were debayered in APP (Ha and Oiii) and processed to RGB with combine RGB image tool.

Looks like some great data, but is it just me or do you have a checkerboard pattern on the image?

Yes, it looks much better with BPM and LNC calibrating  BPM and LNC should always  be applied for OSC and Multi narrowband images
