Description

Image taken during a trip to La Palma Island last week. Very very good seeing for this imaging session, I've been lucky to shot Rho Ophiuchi Region near 40° above horizon. Setup worked perfectly as well :-)

Image réalisée durant un voyage sur l'île de La Palma la semaine dernière. Excellente condition de prise de vue, je suis chanceux d'avoir pu imager cette région du ciel à presque 40° au-dessus de l'horizon. Le setup a également fonctionné parfaitement :-)

Description: Add script "DarkStructureEnhance", redo "CurveTransformation" with mask for colors enhancement in the nebulas only.

Description: I tried this time to work on star field and details enhancement with more accurate masks in Pix. Looks not bad to me. Feedback, comment and criticism are welcome ;-)

Description: As the weather isn't still cooperating with me, I enjoy working on old image, trying to improve my skills in PI. Redo a new stretching process using a mix of MaskedStretch and HistoTransformation to better preserve colors and star shape. Was useful to apply HSV repair just before stretching the image. Final touch-up in PS. Hope you'll like this new version!
