Bonjour.
\nAyant r\u00e9cup\u00e9r\u00e9 le Solar Spectrum que je partage avec Alex, nous avons tent\u00e9 un double stack ce matin avec l’\u00e9talon de mon PST.
\nCa fonctionne plut\u00f4t bien.
\nPour les connaisseurs vous remarquerez que le bord du soleil est plus touffu, on voit moins la limite photosph\u00e8re – chromosph\u00e8re, signe que la filtration est plus fine sur le H-alpha.
\nC’est beaucoup plus cotonneux.
\nImages r\u00e9alis\u00e9es avec la lunette 155 + TZ 4 soit focale 4960.
\nCam\u00e9ra ASI 174,
\nFilms de 20 sec,
\nTemps de pose 15 milli-sec,
\nGain 141,
\nEchantillonage 0.24 sec d’arc\/pix
\nStack de 10 % des images.
\nTraitement ondelettes R\u00e9gistax puis Photoshop renforcement, tons clairs tons fonc\u00e9s, colorisation.<\/p>\n
