Having nothing better to do at the moment, I decided to take a look at combining images done over different years.
Not all the image overlapped, but a fair bit did, but I took a CROP anyway to get in closer to the detail.  Also used some more recently acquired processing tecniques.  Always a good idea to go back and reprocess images as you learn more.
Both being Newtonian's and the spikes going in different directions, I think I got away with it.

Combination of image taken in 2016 with a SW 150P and Atik314L(4 hours)
Plus image taken in 2019 with a 130PDS and Atik460EX (3hours 5mins)

Total 7h 5mins

I nice close up there, some lovely detail and contrast. You handled the spikes well. It's a good reminder to back up my data for future years and the fact that my 150 and 250 newts have very different spike orientation. Was merging and handling the spikes with different scales tricky in photoshop?

To be honest, I didn't do anything to them, they just seemed to blend in.
