Description

Though not without flaws, this timelapse was still fun to put together despite hours of processing each video, stacking, sharpening, manually registering, and false-colorizing.  It's my first attempt at an eclipse timelapse through my double-stacked Lunt H-alpha scope.  It was a memorable weekend with @Bruce Larsen and lots of other family members in Escalante, UT, the best way to view an eclipse!

Individual shots (i.e. short video sequences, each 200 frames at ~7 fps, best 10% stacked in Autostakkert and sharpened in Registax) were taken 5 minutes apart, with the exception of the annularity phase when they were taken only 37.5 seconds apart (i.e. 8 sequences per 5-minute period), for greater coverage of annularity.  To create the timelapse, each 5-minute frame was duplicated 8 times, to keep the timing consistent with the 37.5-sec. frames.  Then everything was stitched together in Photoshop and played back at 24 fps.  In retrospect, it would've been nice to acquire data over 37.5-sec. intervals through the entire event, although I would've gone mad processing that much data, so this will have to suffice.

Looking forward to Apr. 8, 2024!
