Due to weather and the season I could only collect a limited
number of images. Fortunately the object is bright (which
requires less stretching) and the weather was cold so my camera
could run fairly cool.

That is only part of the story. As described in the NB4Stars page, the raw images have to be combined to form an RGB image. I used the following expressions in PixInsight PixelMath.
RED = "NIR_600x8*.33+sYel_600x12*.2";GREEN = "sYel_600x12";BLUE = "sV_600x20+sYel_600x12*.25";
From that point it was just normal processing. Since these were just stars I chose to not aggressively stretch the final image.
