In 2017 I used a Takahashi FSQ 106N to capture 8 RAW images of this nebula at ISO 800 for 240 seconds. No flats or bias frames were taken but I did take 11 dark frames at the same ISO and duration. I tracked with a 60mm guide scope and a SBIG STV. I recently had time to restack these images with DSS and use Photoshop to do the post processing. No filters were used on my Canon 6D MKII camera and I did not dither.
