hello ,
just so as not to lose control, in a milky sky and rotten by the tracks of the plane which do not dissipate pô, with helioscope, always impossible in continuum therefore filter Ha 12nm.

Re: very pale sun of January 7
thank you for your messages
the video is made with a stack of barlow X3 + X2 in continuum 540nm
the images are made with a single X3 barlow and a 12nm Ha filter which calms the seeing down a bit.
it was to show that you shouldn't hesitate to change the filter towards red, you lose resolution but you win in the end to take a few images.
