Hello ,
the sky is not very usable with these trails that never end, I tried again without the Pst stallion but with the Bf 5mm in front of the camera and the erf in front of the lens.
for the prom it works well, for the surface obviously it is not selective enough.
the Bf coronado must be a few Ä (if Christian Villadrich passes by there he will inform us, I believe 6Ä) wide enough for a coronograph.
in the animation without febry-parot we see shiny dots at the bottom, are they Ellerman's bombs ????
Paul
the 2 animations take a long time to load
my sky to start
the assembly of the Bf5
the comparative result unfortunately not at the same time so not necessarily significant raw images out of AS3! with the same number of AP
animation on the surface, no filament but interesting in the spot - long to load
finally comparison of the surface with the Pst standard - very long to load
some images in Ha with the Mod PST

Re: Ha without Fabry – Pérot for the prom
Absolutely amazing Paul I didn't realise you could do that! They are most probably Ellerman bombs as these are seen in the wings of H-alpha and they also come and go in the timelapse. However, they are also in a similar position to the 'Bright ring' as found in CaK too, very interesting indeed!
