solar animation halpha of May 26th

good morning, everyone, like paul's magnificent animation: https://solarchatforum.com/viewtopic.php?f=4&t=28247 that he made of the beautiful prominence present that day; I also split my version. Coincidentally, Paul's version ends (he did it from 4:28 to 15:03 UT ) at the same time as mine begins! ...

solar animation halpha of the 19th of May

good morning, everyone, here is a surface + prominences animation always so laborious to do: the drift being always important in DEC, I have to refocus (literally) every 3 minutes ... and sometimes it goes a little too far. So, instead of cropping to the strictest, I also left the few images that ni...

Re: 2 animations for the price of one of the prominence on May 17th.

thanks to you :) I redid my animation to have a more red color but also a better alignment. Even pregister2 of iris had difficulty on the protuberance because of its shape. And as it seems to be linked to the active area, I made the alignment with respect to the active area : you lose the sun rotati...

2 animations for the price of one of the prominence on May 17th.

good morning, everyone, animation of yesterday's prominence with very average turbulence conditions (especially at the beginning) and a huge DEC drift of the staradventurer who asked me to refocus every 5 minutes (it's laborious) and so I had to do a drastic refocusing! At the fs60 with its sm40 dou...

Re: halpha sun of the 17th of May

thanks to you :) Stephane, I always like your work. Of all the imagers here your work often comes closest to the visual appearance I see at home with my own scopes, minus the yellow color. Visual is red, of course. James I make two full discs for this: the first one is a version increasing the contr...

I chose the brightest protrusion (but, unfortunately, not very evolutionary) for that. And as it was drifting dry in DEC with the staradventurer, the catching castin...
