Exploding arch prom from 9/19

I was messing around with a different optical train to try to get smaller pixel scale per Valery's recommendation, and figured I would grab some sequences of that nice arch prom that Marty put up when I noticed it changing, literally as I was trying to get focus! At first I thought it was my eyes or some funny effect of seeing, but then I could clearly see that the top of the arch was brightening and thinning out, noticeable even over just a period of seconds! So I hurriedly put focus where it seemed best and set up a repeating capture loop in FireCapture; somehow FC misinterpreted my wait settings so I ended up with only a 2 sec delay between 10 sec grabs, instead of the 20 sec delay I had intended. I was hoping to have time to tweak focus in in between frame grabs, but oh well. And then I ran out of disk space, but I was able to grab 60 frames over a period of about 17 minutes. This is batch processed with common settings for stacking, deconvolution, sharpening, and so forth so some frames are a little over done and others a little under but hopefully most are OK. At some point I may go back and try to improve specific frames.

Here's what the arch looked like just before I started the sequence. You can see the brightening of the inside part of the top of the arch that caught my eye.

Thanks for looking! In other news, the relatively cheapo 0.5x High Point FR seems to actually work OK, once I actually found the specs for the spacing.

That is a really cool sequence! The arch opens up and the tongue of plasma flicks through. Nice.

The arch/loop proms are always incredible, but you have captured an awesome event with this sequence.

Well done
