Yr Wyddfa is the highest mountain in Wales at 1085M. I live locally and so its one of my 'go-to' alignment subjects (as can be seen from my youtube channel) :-) Here is a quick timelapse edit from a beautiful late summer evening a few weeks ago.

Nice secenery!
At 0:14 I see a change in Vignetting due to the adjustment of the aperture (see my answer from today here about the issues with aperture ramping: https://forum.lrtimelapse.com/Thread-how...9#pid56959 )
Also there is quite some camera shake. You could try to remove it by stabilizing in the video editor. Next time use a sturdier trypod and try not to touch the camera to avoid such bumps ;-)

Thanks for the comments

re camera shake I tripped over the tripod whilst chatting to a walker who was asking about the setup. The 800mm lens as you know is very susceptible to any slight movement. I also shot in Electronic shutter mode to reduce camera shake. Both my tripods are sturdy Benro Mach3 TMA38 models. I'll investigate the vignetting thread you mention. Thanks.
