this now is extra good seeing, by the ersatz-obsi's measure, btw -- my obsi's location sux 

I inspected videos more closely today, visually scrolling through AS4, with an anchor point dropped onto a thin spectral line, looking for vertical wobble. I saw nothing obvious.

It happens at -72 also. Here I was trying to dig out He I details, 447.15 nm  Let me upload the video and script. Visually, scrolling through the ser...

Present on the tilt image, so at the moment I have three hypotheses - some camera readout issue - pixel level vibrations shifting the spectrum red-blue - some jsolex artefact...

at 300% there is maybe some wobble in the spectral line's position, in this particular video. If the clouds are nice, I'll see how it fares with the screws, an...

Everything trivial is accounted for: - camera and RA-mount-motor fans stop on scan start (and restart on scan finish) - there is ramping to minimize vibrations - cables are arranged...

It's just a shame that the otherwise decent seeing didn't yield the nice pictures I was hoping for. I have a suitcase full of SSDs, so for now I kind...

that's a He I 447.15 filament btw 

I did the following: 1. spacially trimmed the ser video in PIPP to exclude the dark spectral line at the bottom 2. I let JSolex video debugger to crunch the...

I agree with you about cropping to a ROI. However, what a far away line should do is deviate and go off band, not oscillate.
