Ha without Fabry – Pérot for the prom

Post by banjo »

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 ????

the 2 animations take a long time to load

the comparative result unfortunately not at the same time so not necessarily significant raw images out of AS3! with the same number of AP

Absolutely amazing Paul :bow :bow :bow 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!
