First time imaging without the moon in the way in a long time. I had the collimation all set a couple of sessions ago and now it seems to be off for this image. Tracking was excellent and yet I have elongation of stars a bit. Regardless, I am still happy with this and to be imaging again.
Collected the RGB data and this the first LRGB processing attempt
