Description

This time-lapse animation is made up from 120 recordings using an ASI ZWO 174MM through an ExploreScientific 152AR with a DayStar Quark Chromosphere giving a focallength of 4150mm and a samling of 0.29" per pixel. Each recording was 20 seconds @140fps resulting in 2800 frames and 6.3GB of data for a total of 730GB of data. With a 10 second delay between each recording the animation is covering 60 minutes in real time starting 13:41UT

The telescope was mounted on an SkyWatcher AZ EQ6 Pro in EQ-mode and guided with a Hinode SolarGuider. 

The best (sharpest) 400 frames from each recording was then stacked in AutoStakkert!3 before they were aligned, sharpened and contrast-stretched in ImPPG. The animation was created in PIPP at 12 fps effectively compressing the 60 minutes down to 10 seconds.
