AR 3038 in WL + granulation time lapse

Post by GreatAttractor »

The seeing on Thursday was mediocre, but my 3-hour session yielded a few good stacks. All taken with Intes M715, Baader ND 3.8 solar film + Solar Continuum filter, Blackfly S (IMX 273), processed with AS!3 and ImPPG.

High-cadence granulation time lapse (my first; the old ones from 2012 used 1-4 minute intervals, here it's just 15 s, 9 minutes total):

Finally, a fast-forward animation spanning the whole session (3:11 h total); note the twist of the lower sunspots and the dis/appearing pores:

That Intes seems to be working very well, the animation is fascinating to watch!

The Sun's photosphere behaves as if it's a liquid though it's actually a very hot plasma. Filip, your animations show this so clearly in a way no still image can.

Has a feeling of 3-dimensionality as the sunspots appear to show depth!

Thank you, everyone.

Indeed! For now (at 540 nm) it's on par with my old SW Mak 180, but since it's a Rutten-MC, I'm hoping for equally good results - and higher resolution - at near UV (judging by this analysis by Christian). I've already got a few broadband filters (CWL between 450-395 nm, bandwidth 8.5-40 nm) to try out, just waiting for exceptional seeing (...might take a while).
