Description

Time-lapse animation of AR3038 created from 557 recordings between 11:28UT and 16:13 on June 24th 2022. Each recording was 20 seconds long with a forced framerate of ~50fps (1000 frames) and a 10 seconds delay between each recording. The recordings where made using an ASI ZWO 174MM together with a DayStar Quark Chromosphere through an Explore Scientific 152AR masked down to 140mm f/7. This setup gave a focallength of 4250mm f/30.4 and a sampling of 0.28" per pixel. The telescope was mounted on an SkyWatcher AZ EQ6 Pro in EQ-mode and guided with a Hinode SolarGuider. 

The best (sharpest) 100 frames from each recording was stacked in AutoStakkert!3 before they were aligned, sharpened and contrast-stretched in ImPPG. Another tweak of contrast was done in PS before the files were deflickered using GbDeflicker.  

The images was then downsized to 80% (to save some bandwith) in PIPP before creating the time-lapse at 12 fps - effectively compressing the 4 hours 45 minutes of duration down to a mere 46 seconds.
