Laboratorium Solaris: total addiction
19.02.2015, around 11:00 GMT+4
Evolution of the prominences along the eastern limb of the Sun in comparison with yesterday's image.
I have pushed the brightness of proms to get the fine things out and... See supplementary material in "comments" section :)
Acquisition: Coronado PST, 1/2 of Meade 2x Barlow lens and TIS DMK23U274, alltogether on tabletop Celestron CG-4 with motor.
Processing: Autostakkert!2, AstraImage PRO 3.0 and Photoshop.
Technical note: if the size of a frame is something like 1080x960, Autostakkert!2 opens the movie but scrambles the contents. I have used ImageJ to open the film and resave it as a sequence of tiffs. Strange, but it comes out flipped in comparison with the image in capturing software.
