I had to go and do some work (I know, shocking!), so I left my little Lunt50 to it.
Unfortunately, I ran into some trouble. This is the first time I have screwed the camera directly to the diagonal. I ended up with a bright center ring in the image, which I can only presume is from being too close to the tiny 4mm hole? Never had this problem before. Flats might have fixed it, but that was problem number 2. It failed 😔
So I have not spent much time processing this! 😀 I just ran it through my Photoshop scripts, and made the animation. Done!
