Stacked in DSS with Darks,Flats, and Bias/offset frames all at the same sensor temperature.
I have added a couple of arrows to show the location of the SN and adjacent star. I noticed that in mine I am seeing an orange tinge to the SN, perhaps the nature of my camera spectrum range. As usual with RCs the diffraction of bright stars can get in the way of small details like the gap, still it looks ok and has not been overly stretched, just auto leveled in Photoshop and a crop to keep the size down.

The red/orange colour is because the supernova is embedded in the dust of the galaxy,which is called extinction,just like the sun is red in the evening sky low down on the horizon, small dust particles darken the light toward the red.
Nice pic BTW.
