halpha sun of April 18

Post by stef41 »

Good morning, everyone,

a sunny sky at home but with a lot of cirrus clouds and wind and a lot of turbulence...and as, during the week, I can only make the sun late enough; a rather low target.
In short, not easy, but fortunately, a little activity on our star today.

At fs60 with sm40 double stack, glasspath x1.25, BF10 and zwo178mm around 16h UT

and an attempt at animation despite the conditions (because I missed it) of the little eruptive protuberance with powermate x2.5
36 films of 9s (at 110fps) every minute between 16h16 and 17h UT

gif reduced to 35%

Image

xvid at 5fps reduced to 75%

thanks for your comments :)
the animation would have been better without these cirrus...

I hope I can start again tomorrow with a better sky ;)

cordially,
Stéphane
