Complete telescopic analysis of a remarkable region of the moon using all the techniques available to an amateur: high definition imaging (HD), natural color imaging, spectral imaging (ratio of narrow bandwidth filters: 450, 750 and 900 nm – Equivalent to those used by the american probe Clementine)
Analyse téléscopique complète d’une région remarquable de la lune en utilisant toutes les techniques disponibles pour un amateur : imagerie haute définition (HD), imagerie couleur naturelle, imagerie spectrale (ratio de filtres à bande passante étroite : 450, 750 et 900 nm – Equivalents à ceux utilisés par la sonde américaine Clementine)
Takahashi Mewlon 250 CRS 250 f/2500 mm – ZWO ASI 290MM – ZWO ASI 178MC – 0.14”/pixel image scale – (300/9000 frames) – Mosaic 2 tiles – Image processing: Autostakkert V3 & PixInsight V1.8
Moon color-ratio mineral map using 3 spectral filters
RED: 750/415 nm. Low in titanium or high in glass content. Also red in the false-color image are pyroclastic deposits because of their high-glass content.
GREEN: 750/900 nm. Sensitive to the amount of iron on lunar surface. The yellow-green area in the mare is the combined effect of concentration of mafic mineral (green) and the glass in the soil produced by maturation (red).
BLUE: 415/750 nm. Surface with high titanium or bright slopes or albedo that are not compensated by using the image ratio.The blue unit in the mare is relatively higher in titanium compared to the mare unit to its immediate north.
