Re: Solar Granulation 31st May '20

nice work :) Excellent details. I read somewhere that the life span of a convection cell is around 20 minutes. Would it be interesting to make a time lapse ? Professionals can do it.

Re: solar animation halpha of May 26th

thanks to you :) Lovely animation with your SM40, I am interested in why you use an ADC. John I use ADC for two things: - To remove the newton rings (like a tilt ring). - and I'm using it as the body of a barlow to get an F/D of 14... Absolutely wonderful!! and to carry on where Paul left off is tre...

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.

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

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...
