Description

First attempt to animate a set of 680 frames created at 2min intervals with 10 manual exposures each, that were subsequently stacked and sharpened (deconvoluted) to create 68 TIF-Files. These were motion-interpolated for a smoother video using FFMPEG, then converted from MP4  to animated GIF (which increased file size by a factor of 6, but required by Astrobin's policies). There's obviously quite some loss of quality during conversion to GIF , so a processed still image is marked as "Final Revision" to demonstrate the quality that could actually be achieved with the little Lunt (35mm Aperture) when there's a moment of good seeing , as well as a link to the orginal MP4 version (if you view it online, it may be helpful to set the option  "zoom only text" in your browser and resolution to HD).

The animation is probably best viewed at "Full resolution", as there seem to be some strange artefacts (apart from minor ones from motion interpolation) created in some browsers otherwise...

As an aside, I made about all errors one could make during capture, two most significant being:
1. Fiddling with focus and Etalon settings between each set ... just don't do it!
2. Giving little attention to balance ( and then not daring to correct) resulting in continuous, but sporadic rotation of field  ...  feeble excuse is I was a little late in setup and eclipse started 5 min earlier than anticipated, so there was no time for correct balance after first set of pics ...

1. and 2. (together with haze and even a plane) resulted in the wavering of surface details and rotation.

Well ...it appears next opportunity here from Vienna/Austria will be 2026 ... hope to do better then (if still alive) ;-)
